I am writing a script that locates a special type of file on my system and i want to check if those files are also present on a remote machine. So to test a single file I use: ssh -T user@host [[ -f /path/to/data/1/2/3/data.type ]] && echo "File exists" || echo "File does not exist"; But since I have to check blocks of 10 to 15 files, that i would like to check in one go, since I do not want to open a new ssh-connection for every file. My idea was to do something like: results=$(ssh "user@host" ' for file in "${@}"; do if [ -e "$file" ]; then echo "$file: exists" else echo "$file: does not exist" fi done ' "${files_list[@]}") Where the file list contains multiple file path. But this does not work, as a result, I would like to have the "echo" string for every file that was in the files_list.

Is there any variable that cron sets when it runs a program ? If the script is run by cron, I would like to skip some parts; otherwise invoke those parts. How can I know if the Bash script is started by cron ?

The goal is to get modbus ascii working with a Wallbox from ABL. So I placed a RS485 to TCP converter in the box, created a pseudo tty for my application and got the wrong frame. The answer starts with > and should start with :. So my approach is the following:

Terminal1: sudo socat -d -d -d pty,link=/dev/ttyVA00,echo=0,perm=0777 pty,link=/dev/ttyVB00,echo=0,perm=0777

Terminal2: sudo socat -d -d -d pty,link=/dev/ttyV0,perm=0777 tcp:10.10.49.249:502

Terminal3: cat /dev/ttyVB00 > /dev/ttyV0

Terminal4: cat /:/g' > /dev/ttyVB00
           
Terminal5: ./modpoll -m ascii /dev/ttyVA00 -b 38400 -d 8 -p even -t4 -c 2 -0

And this works! Could you give advice on how to simplify the socat solution and how to get it to autostart?

I have a shell script which sucessfully redirects all output to a log file and stdout (console) at the same time. However, when it exits it seems to wait for some user input from the keyboard (experimentally, any key seems to work)... So, I run the script, see the output, it exits and I have to hit e.g. the spacebar before the terminal prompt re-appears. Typing echo $? then gives the correct exit code. The basics of the script are: #!/bin/bash LOG="./test.log" rm -f $LOG exec > >(tee $LOG) 2>&1 if [[ "$1" = "T" ]]; then echo "twas true..." exit 0 else echo "twas false..." exit 100 fi Any help appreciated... not only do I not want to hit the spacebar but I would like to understand what is going on? ***Amendment***: it appears that I have to hit **enter** to get the terminal prompt back. From my limited experience using the *ps* command it would seem that my script has terminated and the *bash* shell is in the interruptible sleep state **S**. It would appear that maybe the terminal prompt output has been consumed or incorrectly redirected? I cannot see why...

I am doing the second BASH exercise from TLDP Bash-Scripting Guide , and I have most of it figured out up until the part when it comes time to copy the compressed files to an inserted USB. > Home Directory Listing > > Perform a recursive directory listing on the user's home directory and save the information to a file. Compress the file, have the script > prompt the user to insert a USB flash drive, then press ENTER. > Finally, save the file to the flash drive after making certain the > flash drive has properly mounted by parsing the output of df. Note > that the flash drive must be unmounted before it is removed. As I progress with the script it is becoming less ..elegant, and was wondering if there was a better way to do this. I know creating files is likely not the most efficient way to do the comparisons, but have not got the shell expansions figured yet, and intend to change those once I get it working. The problem specifically is, to ensure that the usb is mounted and that I am writing to the USB and nowhere else. I am comparing the last line of df after the USB is plugged in with the last line of df from the diff between df before USB is plugged in and df after USB is plugged in, and looping until they match. Unfortunately, the diff result starts with a >, but I intend to use sed to get rid of that. The real problem is the path to where my usb is mounted is: > /media/flerb/"Title of USB with spaces" To make this portable for USBs that may have different names is my best bet from here to do something with awk and field separators? And as a follow-up, I know this is pretty inelegant, and wonder if there is a cleaner way to go about this...especially because this is the second exercise and still in EASY. The output from the df tails is: /dev/sdb1 15611904 8120352 7491552 53% /media/flerb/CENTOS 7 X8 > /dev/sdb1 15611904 8120352 7491552 53% /media/flerb/CENTOS 7 X8 The script so far 1 #!/bin/bash 2 3 if [ "$UID" -eq 0 ] ; then 4 echo "Don't run this as root" 5 exit 1 6 fi 7 8 #Create a backup file with the date as title in a backup directory 9 BACKUP_DIR="$HOME/backup" 10 DATE_OF_COPY=$(date --rfc-3339=date) 11 BACKUP_FILE="$BACKUP_DIR/$DATE_OF_COPY" 12 13 [ -d "$BACKUP_DIR" ] || mkdir -m 700 "$BACKUP_DIR" 14 15 #find all files recursively in $HOME directory 16 find -P $HOME >> "$BACKUP_FILE" 17 18 #use lzma to compress 19 xz -zk --format=auto --check=sha256 --threads=0 "$BACKUP_FILE" 20 21 #making files to use in operations 22 BEFORE="$BACKUP_DIR"/before_usb.txt 23 AFTER="$BACKUP_DIR"/after_usb.txt 24 DIFFERENCE="$BACKUP_DIR"/difference.txt 25 26 df > "$BEFORE" 27 read -p 'Enter USB and press any button' ok 28 sleep 2 29 df > "$AFTER" 30 diff "$BEFORE" "$AFTER" > "$DIFFERENCE" 31 sleep 2 32 echo 33 34 TAIL_AFTER=$(tail -n 1 "$AFTER") 35 TAIL_DIFF=$(tail -n 1 "$DIFFERENCE") 36 37 until [ "$TAIL_AFTER" == "$TAIL_DIFF" ] ; 38 do 39 echo "Not yet" 40 df > "$AFTER" 41 TAIL_AFTER=$(tail -n 1 "$AFTER") 42 diff "$BEFORE" "$AFTER" > "$DIFFERENCE" 43 TAIL_DIFF=$(tail -n 1 "$DIFFERENCE") 44 echo "$TAIL_AFTER" 45 echo "$TAIL_DIFF" 46 sleep 1 47 48 done 49 exit $?

I would like to write a script to search through /usr/dict/words to find all words that meet some criteria I specify. For example, finding all palindromic words (like "racecar", "madam", etc.) or finding all words where the first and second halves reversed also form a word (like "german" and "manger"). The framework of the script would be a simple loop to read each word in the dictionary, and I could change the criteria depending on what I want to look for by substituting an expression or something similar. I figure I would need to involve regular expressions somehow (or otherwise find a way to look at individual characters in each word). I would also need a way to compare the characters in my current word to the other words in the dictionary (such as with my second example above). What would be the best tool(s) to use for this task?

I have two similar scripts with different names. One works fine but other throws error. Can anyone please tell me what is the issue? This is my test.sh scripts which works fine

[nnice@myhost Scripts]$ cat test.sh 
#!/bin/bash
function fun {     
        echo "hostname"
}
fun 
[nnice@myhost Scripts]$ ./test.sh 
myhost.fedora

Here is my another script demo.sh but it throws error

[nnice@myhost Scripts]$ cat demo.sh 
#!/bin/bash
function fun { 
	echo "hostname"
}
fun
[nnice@myhost Scripts]$ ./demo.sh 
bash: ./demo.sh: cannot execute: required file not found

Both scripts having the same permissions

[nnice@myhost Scripts]$ ll test.sh 
-rwxr-xr-x. 1 nnice nnice 65 Oct 21 10:47 test.sh
[nnice@myhost Scripts]$ ll demo.sh

In Linux there are some Folders. I want to process each of this Folders with the program myprogramm. I get a list with ls -1 or much better, sure only Folders with: find . -maxdepth 1 -type d -printf '%f\n' | tr -d '.' | sed '/^[[:space:]]*$/d' I Can pipe this to xargs. xargs -I {} -n1 -P1 $(cat $TEMPDIR)/myprogramm -switch1 -switch2 -someoptions {}/ -o {}.info In one line : find . -maxdepth 1 -type d -printf '%f\n' | tr -d '.' | sed '/^[[:space:]]*$/d' | xargs -I {} -n1 -P1 $(cat $TEMPDIR/pwd)/myprogramm -switch1 -switch2 -someoptions {}/ -o {}.info That works so far. But i am looking for a way to bring a little bit info into it. Everytime if myprogramm ends, it would be nice to have an output like: Folder 1 of 22 finished Count how many Folders exist can i do with: find . -maxdepth 1 -type d -printf '%f\n' | tr -d '.' | sed '/^[[:space:]]*$/d' | wc -l But how to bring this into the line they process each Folders? And how to count after every one is finished one up? Next thing, how to bring a random sleep value after every finished myprogramm run and count them down before to work at the next Folder? A random sleep can do with sleep $(shuf -i 30-60 -n 1). But how to bring this into, and how to show and count them down?

I have 3 strings A='apples' B='bananas' C='carrots' I want to see if all of these exist in the fruit.txt file. If I'm missing A then add A, B then add B, and so on. This is what I have now if grep -qF "$A | $B | $C" fruit.txt; then echo 'exist' else echo 'does not exist' echo $A $B $C >> fruit.txt fi

Kinda stuck here, did not find any solution. Check if user exists in /etc/passwd, if they exist, create new one with prefix new_the_existed_one

#!/bin/bash

myuser="/home/yakyak/Desktop/Exercises/newusers.txt"

sed '/^[ \t]*$/d' $myuser | while read -r line
do
        name="$line"
        # adduser --disabled-login --gecos "" $name
        # check if user exist
        isthere=$(cut -d: -f1 /etc/passwd | grep "$name")

        # if user was added then make insert record into log file
        if [[ "$isthere" == "$name" ]]
        then
            echo "User already exist, creating new user.."
            adduser --disabled-login 
            # adduser --disabled-login --gecos " " $name
        fi

I have a third-party service. Its API and credentials let me scrape service data on my local Linux machine. I want to use this API inside a bash script and launch it via cron, but I don't want to store credentials in plain text in the script. What are the best practices for authentication?

This is what I have so far: until python MyApp.py; do echo "App crashed... restarting..." >&2 sleep 1 done This will re-run the program when it crashes, but not when the program finishes on its own.

I tried this grep -rn "application_config_project" . I got many application_config_project_name = f"{app_acronym}-application-config" github_application_config_repo = application_github_organization.get_repository(application_config_project_name) f"Initializing Application Config Project {application_config_project_name}" how to restrict my search just to application_config_project?

In Linux in a directory there are files, ls -1 shows me this output : file1.1-rvr file1.2-rvr file1.3 file1.4-rvr file1.5 file1.6-rvr file2.1 file2.2 file3.1 file3.10 file3.2-rvr file3.3-rvr file3.4 file3.5 file3.6 file3.7 file3.8 file3.9 file4.1 file4.2 file5.1-rvr file5.2 file6.1 file6.2 file6.3 file6.4 file7.1 file7.2-rvr file7.3 file7.4 file7.5 file7.6 file8.1 file8.2 file8.3-rvr file8.4 In this directory are only files with file names that begin with file. There are no other files in there. file1.* is a package file2.* is a (different) package too and so on. Each package should have its own random name. For the randomness i will use. cat /dev/urandom | tr -cd 'a-zA-Z0-9' | head -c $(shuf -i 8-32 -n 1) In each package, the . should be renamed to .part.rar. Files with -rvr should renamed too. For example: file3.1 file3.10 file3.2-rvr file3.3-rvr file3.4 file3.5 file3.6 file3.7 file3.8 file3.9 should be renamed for testing and experimenting to: rfiqDLhZF5XxRcJXkqR1LrwniDi.part01.rar rfiqDLhZF5XxRcJXkqR1LrwniDi.part10.rar rfiqDLhZF5XxRcJXkqR1LrwniDi.part02.rar rfiqDLhZF5XxRcJXkqR1LrwniDi.part03.rar rfiqDLhZF5XxRcJXkqR1LrwniDi.part04.rar rfiqDLhZF5XxRcJXkqR1LrwniDi.part05.rar rfiqDLhZF5XxRcJXkqR1LrwniDi.part06.rar rfiqDLhZF5XxRcJXkqR1LrwniDi.part07.rar rfiqDLhZF5XxRcJXkqR1LrwniDi.part08.rar rfiqDLhZF5XxRcJXkqR1LrwniDi.part09.rar (If there are a *.10, 1 must be rename to 01.) But there must be a way to note (in a file ../renamed) the renaming in order to rename them back to the original filenames later. For renaming all files in random names, i can use this, but i dont know how to work with the .part.rar renaming. for file in file*; do while true; do RANDOM_NAME=$(cat /dev/urandom | tr -cd 'a-zA-Z0-9' | head -c $(shuf -i 8-32 -n 1)); if [ ! -f ${RANDOM_NAME} ]; then echo "${file}" "${RANDOM_NAME}" >> ../renamed mv "${file}" "${RANDOM_NAME}"; break; fi done done For renaming back, i can use this one liner : `while read old new rest ; do mv $new $old ; done .rar and back again. EDIT I am looking for a way to do that in Bash. Here is a complete list with the current file names and the new filename scheme: current name new name ------------ -------------------------------------- file1.1-rvr --> cL5617iQyc8kT5GwNoi.part1.rar file1.2-rvr --> cL5617iQyc8kT5GwNoi.part2.rar file1.3 --> cL5617iQyc8kT5GwNoi.part3.rar file1.4-rvr --> cL5617iQyc8kT5GwNoi.part4.rar file1.5 --> cL5617iQyc8kT5GwNoi.part5.rar file1.6-rvr --> cL5617iQyc8kT5GwNoi.part6.rar file2.1 --> QuMPmQjppRSuG3QL9xy5.part1.rar file2.2 --> QuMPmQjppRSuG3QL9xy5.part2.rar file3.1 --> rfiqDLhZF5XxRcJXkqR1LrwniDi.part01.rar file3.10 --> rfiqDLhZF5XxRcJXkqR1LrwniDi.part02.rar file3.2-rvr --> rfiqDLhZF5XxRcJXkqR1LrwniDi.part03.rar file3.3-rvr --> rfiqDLhZF5XxRcJXkqR1LrwniDi.part04.rar file3.4 --> rfiqDLhZF5XxRcJXkqR1LrwniDi.part05.rar file3.5 --> rfiqDLhZF5XxRcJXkqR1LrwniDi.part06.rar file3.6 --> rfiqDLhZF5XxRcJXkqR1LrwniDi.part07.rar file3.7 --> rfiqDLhZF5XxRcJXkqR1LrwniDi.part08.rar file3.8 --> rfiqDLhZF5XxRcJXkqR1LrwniDi.part09.rar file3.9 --> rfiqDLhZF5XxRcJXkqR1LrwniDi.part10.rar file4.1 --> cLYtCmUW.part1.rar file4.2 --> cLYtCmUW.part2.rar file5.1-rvr --> uXjOgcreTUCC7aHKkXeWPL1SiVdX.part1.rar file5.2 --> uXjOgcreTUCC7aHKkXeWPL1SiVdX.part2.rar file6.1 --> 9CcsiBYcuASF0ECoS.part1.rar file6.2 --> 9CcsiBYcuASF0ECoS.part2.rar file6.3 --> 9CcsiBYcuASF0ECoS.part3.rar file6.4 --> 9CcsiBYcuASF0ECoS.part4.rar file7.1 --> SXKymGb5Z9ImrQ0K51IUAA.part1.rar file7.2-rvr --> SXKymGb5Z9ImrQ0K51IUAA.part2.rar file7.3 --> SXKymGb5Z9ImrQ0K51IUAA.part3.rar file7.4 --> SXKymGb5Z9ImrQ0K51IUAA.part4.rar file7.5 --> SXKymGb5Z9ImrQ0K51IUAA.part5.rar file7.6 --> SXKymGb5Z9ImrQ0K51IUAA.part6.rar file8.1 --> 5poLf4stv6.part1.rar file8.2 --> 5poLf4stv6.part2.rar file8.3-rvr --> 5poLf4stv6.part3.rar file8.4 --> 5poLf4stv6.part4.rar But all before .partX(X).rar should be random and generate with : cat /dev/urandom | tr -cd 'a-zA-Z0-9' | head -c $(shuf -i 8-32 -n 1)

I got this Python script that reads media files from USB stick. It used to run fine, today it keeps giving me OS Error: [Errno 13] Permission denied: media/myName/usbName when the script runs the command os.listdir(). os.listdir() simply checks what folders and files are in the main folder. It doesn't write anything, so why is there a permission error? I can use the USB stick just fine, open, add and delete files in it myself. I'm not very experienced with Linux, what might be the issue? Some kind of permission, etc. setting for the script file or the usb drive that somehow magically changed without me doing anything? Using Lubuntu 14.04.

I have written a script that runs fine when executed locally: ./sysMole -time Aug 18 18 The arguments **"-time"**, **"Aug"**, **"18"**, and **"18"** are successfully passed on to the script. Now, this script is designed to be executed on a remote machine but, from a local directory on the local machine. Example: ssh root@remoteServer "bash -s" < /var/www/html/ops1/sysMole That also works fine. But the problem arises when I try to include those aforementioned arguments **(-time Aug 18 18)**, for example: ssh root@remoteServer "bash -s" < /var/www/html/ops1/sysMole -time Aug 18 18 After running that script I get the following error: bash: cannot set terminal process group (-1): Invalid argument bash: no job control in this shell Please tell me what I'm doing wrong, this greatly frustrating.

Does anyone know of an open source application or perhaps how to integrate an existing find dupes script with some OS tool (emacs, vim, Finder.app, mc, etc...) to open a file before marking that file for deletion? And perhaps know of open source Unix based console based tools that manage and delete duplicate files? I'm using MacOS. I'm asking here because it's Unix related and I'm hoping to leverage some dupes scripts if necessary. I created the following script to find duplicate files and create output with #rm duplicate_filen in groups such that a line can be commented out and the script invoked to delete duplicates. I'm wondering if such scripts could be used with other applications. Hoping to ask here before reinventing this. #!/usr/bin/env ksh FINDOUT=$(mktemp) ( find "${@}" -type f -print0 | xargs -0 shasum ) > $FINDOUT HASHES=$(find "${@}" -type f -print0 | xargs -0 shasum | awk '{ print $1; }' | sort | uniq -d) DUPELIST=$(mktemp) DUPES=$(mktemp) for h in $HASHES; do if grep "^$h " $FINDOUT >> $DUPES; then echo "" >> $DUPELIST cat $DUPES >> $DUPELIST fi rm $DUPES done RMSCRIPT=$(mktemp) cat $DUPELIST | cut -d " " -f 2- > $RMSCRIPT echo "#!/usr/bin/env ksh" echo "# Duplicate files, remove comments and invoke script" while read -r l; do if [ "$l" != "" ]; then echo "#rm \"$l\"" else echo $l fi done < $RMSCRIPT rm $FINDOUT $RMSCRIPT $DUPELIST

I am using Ubuntu Linux and Mageia Linux... I wish to do the following: in a text file (sample.txt), find and delete every line comprising the symbol '#' (or '?') or a specific word (e.g. 'mobile') Any idea how to start ? Thanks a lot Vincent

I created a ClamAV on-access scanning systemd service, to be permanent so that I can enable, start and then leave it, without having to touch it again. I can manually start the service, and it works fine. But it keeps failing to start automatically after login as expected. In both cases, there are no active network connections. I believe the following journal output (found in last ouput section of the post) could be a clue:

rc.local: ERROR: ClamClient: could not connect to remote clam daemon, Couldn't connect to server
rc.local: ERROR: Clamonacc: daemon is local, but a connection could not be established

But I still don't why I'm able to manually start the service, but not have it start automatically. # System info

I have been running inotify-wait on my ftp server in byobu to monitor a folder, move data, and send email notifications for a few months without problems. Since I started this I have added 3 more folders that I monitor and I would like to start running inotify-wait as a daemon instead of in byobu sessions. I modified my script to be easier to only require a single variable to be changed and to run as a daemon. Unfortunately it now does nothing. I was hoping someone with some experience could take a look and tell me where Ive gone wrong. #!/usr/bin/env bash user=testuser dir=/ftp/"$user"/upload/ log=/ftp/"$user"/log/"$user.log" archive=/ftp/"$user"/archive/ target=/ftp/FTPDATA/"$user"/ inotifywait -q\ -d "$dir" \ -o "$log" \ -e close_write --format %f . | while IFS= read -r file; do cp -p "$file" "$target" /scripts/"$user-notify.sh" mv "$file" "$archive""$(date +%F-%T)" done
