I have 2 files: nand and spare. I need to combine them like this: first 512b from nand + first 16b from spare + second 512b from nand + second 16b from spare + and so on I'm on Kali.

If you all look at the enclosed image above, you can see that I've merged four hard drives into one volume group called MQ. I did this in order to try to have my system hard drive (KINGSTON SUV400S) merged with the volume group MQ so that it would show up as one big system drive. The reason why I want to do this is so I can install all the additional graphics drivers I need for Ollama to run my AI model on my GPU and not just my CPU, as it is now. The reason for why I'm asking this question is because the system drive ran out of storage space when I installed the graphics drivers which made the computer unbootable for a while. Can someone give me directions on how to do this, or is this impossible?

I'm using git. I did a normal merge, but it keeps asking this: # Please enter a commit message to explain why this merge is necessary, # especially if it merges an updated upstream into a topic branch. And even if I write something, I can't exit from here. I can't find docs explaining this. How should I do?

I have folder with files named like 0001.mp4, 0002.mp4, ... I want to merge all these files to a combined.mp4, and I want it to have an internal chapter marks. It is convenient when playing for example in vlc, as you can see the chapter names in timeline. How can I make such combined.mp4? Preferably, command line script using ffmpeg, and no additional dependencies. There is similar question, but asker wants to use handbrake.

I have around 500+ files and I know how to merge them. But the problem is I would like to merge them in such a way that every file starts with the file neme in its first page. For example I have 3 files (fila1,file2,file3) and each file has 10,20 and 30 pages. I need the merged file in such a way first page would be FILENAME that is file1 then the complete first file , then name of second file in one page followed by the file and so on.... How could I do so?

This is clearly one of those "I've missed the basic principle" type issues. Luckily since everything is now "on the web" I can be very specific and not need to say "for example" (but it's the principle I want to understand). [FYI: This got moved from "stackoverflow" because it's not about programming ... strictly true I guess ... but mostly for programmers ] [AFYI: It seems some folks go around searching keyword matches on questions , then posting links to any that match ... so I've already found many links were people did a merge from another repo ... and it worked ...if that was the answer I'd not have posted this question] I developing some code to drive an e-ink display. The code is at: https://github.com/waveshareteam/e-Paper I came across a bug and went to open an "issue" , while there I spotted there were quite a lot of "issues" and a lot of waiting "pull requests". Reading though these I realised I'd quite like some (one for now) in my version. The one I wanted was : https://github.com/rohoog/e-Paper (lots of fixes to avoid busy waits) ...Now I didn't do this is the methodical fashion implied here but:

git clone             https://github.com/waveshareteam/e-Paper 
git remote add rohoog https://github.com/rohoog/e-Paper 
git fetch  rohoog  --tags

I then did:

$ git branch -r
WARNING: terminal is not fully functional
Press RETURN to continue

  origin/master

$ git checkout master
$ find RaspberryPi_JetsonNano > /tmp/origin-master-RaspberryPi_JetsonNano
$ diff /tmp/origin-master-RaspberryPi_JetsonNano  /tmp/rohoog-master-RaspberryPi_JetsonNano

The diff returned many differences. So next, I did:

$ git diff origin/master rohoog/master  > /tmp/diffs

$ wc /tmp/diffs
  561055  1374852 25309866 /tmp/diffs

(so maybe , I'll regret trying to do this ...but let's see ..I only care about a few files)

$ git branch

$ git merge rohoog/master
Already up to date.

OK...what? How? I can see many people have had similar "blind spots" but it feels like I've followed the guidelines. What am I doing wrong? Well there are many thousands of lines different, I'd expect something to get changed? OK, taking comments from @Terdon: I think the mistake I made was: Whereas I had thought the situation I was in was : So there were no new patches to add.. However when I did the "diff(1)" what I was seeing there the 99+ patches (deltas) that had happened in the original repo. As you can see what I was expecting to pick up were patches P1-P7 (made up numbers here) because I thought the rohoog fork had rolled up all the changes into his master. I fact they are all separate, so since I want the "wait-pin" work I need patches P3-P5 , so I should merge from the tip of "wait-pin" branch. Have I got this about right? Any suggestions as to a simple check I should have done to ensure I spotted the "problem" (my misperception) . (e.g. I was mostly guessing , working back from github pull request to the [wrong] git branch)

I am looking to merge two different JSON files into one file - file 1 [ { "namespace": "lerjr-rb26-sandbox-keycloak", "name": "keycloak", "url": "REMOVED" }, { "namespace": "prometheus-brr1-sandbox", "name": "abacus", "url": "REMOVED" }, { "namespace": "prometheus-brr1-sandbox", "name": "keycloak", "url": "REMOVED" }, { "namespace": "prometheus-nginxredirect-sandbox", "name": "riskpoynt-redirect444", "url": "REMOVED" }, { "namespace": "prometheus-nginxredirect-sandbox", "name": "riskpoynt-redirect447", "url": "REMOVED" }, { "namespace": "prometheus-x105-sandbox", "name": "epas", "url": "REMOVED" }, { "namespace": "prometheus-x105-sandbox", "name": "epas-oidc", "url": "REMOVED" }, { "namespace": "prometheus-x105-sandbox", "name": "keycloak", "url": "REMOVED" } ] file 2 [ { "namespace": "ler-rb26-sandbox", "labels": { "pg.customerName": "prometheus", "pg.customerCode": "rb26", "pg.product": "keycloak", "pg.environment": null } }, { "namespace": "lerjr-rb26-sandbox-keycloak", "labels": { "pg.customerName": "lerjr", "pg.customerCode": "rb26", "pg.product": "keycloak", "pg.environment": null } }, { "namespace": "prometheus-brr1-sandbox", "labels": { "pg.customerName": "prometheus", "pg.customerCode": null, "pg.product": null, "pg.environment": null } } ] EXPECTED OUTPUT [ { "namespace": "lerjr-rb26-sandbox-keycloak", "labels": { "pg.customerName": "lerjr", "pg.customerCode": "rb26", "pg.product": "keycloak", "pg.environment": null }, "ingresses": [ { "name": "keycloak", "url": "REMOVED" } ] }, { "namespace": "prometheus-brr1-sandbox", "labels": { "pg.customerName": "prometheus", "pg.customerCode": null, "pg.product": null, "pg.environment": null }, "ingresses": [ { "name": "abacus", "url": "REMOVED" }, { "name": "keycloak", "url": "REMOVED" } ] }, { "namespace": "prometheus-nginxredirect-sandbox", "labels": { "pg.customerName": "null", "pg.customerCode": null, "pg.product": null, "pg.environment": null }, "ingresses": [ { "name": "riskpoynt-redirect444", "url": "REMOVED" }, { "name": "riskpoynt-redirect447", "url": "REMOVED" } ] }, { "namespace": "prometheus-x105-sandbox", "labels": { "pg.customerName": "null", "pg.customerCode": null, "pg.product": null, "pg.environment": null }, "ingresses": [ { "name": "epas", "url": "REMOVED" }, { "name": "epas-oidc", "url": "REMOVED" }, { "name": "keycloak", "url": "REMOVED" } ] } ] NOTE that the final product has labels (null if not present) and if there are no ingresses the namespace entry is removed. the namespace key/value pair is the link between the two files - file 1 is the primary file I suppose, I do not want the namespace entry from file 2 if there is no namespace entry in file 1.

I have to send an email from my development server, the mail body is having some 20 lines. But Few lines are getting merged. I have tried no of scenarios (used mailx,mail & sendmail also) to avoid this, but still the lines in body mail are getting merged. $ cat check.txt Company*+ ! 1000000001!: Global Operations Last Name* ! 1000000018!: Global Operations First Name* ! 1000000019!:Generic **command used to send this mail:** mailx -s "FAILURE" < check.txt "abc@gmail.com" **Received Output in mail:** Company*+ ! 1000000001!: Global Operations Last Name* ! 1000000018!: Global Operations First Name* ! 1000000019!:Generic Let me know if I am doing any wrong in the code.

In the example below,

is a directory containing many subdirectories. The contents of each subdirectory, which are directories themselves, should be merged with

/su/destdir

, which already contain directories of the same names. The end result, for example, should be a filesystem where

/su/destdir/a

contains the files and directories already in

/su/destdir/a

, and additionally the files and directories in

/home/user/exdir/412/a

,

/home/user/exdir/754/a

, and finally

/home/user/exdir/612/a

. Any changes made in

/home/user/exdir/*

would thus effect any executable that reads the directory

/su/destdir

when this union is active. If not active, the

/su/destdir

directory should appear unchanged.

I have 96 *fastqc.gz raw read files from 24 samples. Each sample was sequenced on two lanees for each pair. I would like to merge reads for each pair from both lanes into one output file with same name identifier from sample file name (2271_merged_R1_001.fastq.gz). File names are in this order: 22[71-94]*R[1-2]_001.fastq.gz; **2271**_ID890_1_S1_L001_**R1_001.fastq.gz** **2271**_ID890_1_S1_L002_**R1_001.fastq.gz** **2271**_ID890_1_S1_L001_**R2_001.fastq.gz** **2271**_ID890_1_S1_L002_**R2_001.fastq.gz** I tried the following short script but only two output files are being generated (first and the last). FOR R1 files for rf in 22[71-94]*R1_001.fastq.gz; do zcat $rf > 22"${71-94}"_merged_R1_001.fastq.gz ; done FOR R2 files for rf in 22[71-94]*R2_001.fastq.gz; do zcat $rf > 22"${71-94}"_merged_R2_001.fastq.gz ; done My Questions are: 1. Why only two output files are generated? 2. The number of reads in the out put files are not the sum of the merged files from both lanes. 3. Is there a nice way, I could do the merging of reads from both lanes for both (R1 and R2) in single step instead of running it two times for each read type. What went wrong in the code? and how could I verify that the output files are completely merged? Thanks

I am searching for a nice method of merging two or more files line by line using the zipper method (also called late merge). Assuming we have three files, the result should look like this: line1 file1 line1 file2 line1 file3 line2 file1 line2 file2 line2 file3 ... **EDIT** I wrote a little python script capable of doing this: #!/usr/bin/python import sys, itertools fileList = [] for file in sys.argv[1:]: f = open(file, "r") fileList.append(f.read().split("\n")) for z in itertools.izip_longest(*fileList): print "\n".join([i for i in z if i is not None]) I still wonder if there is any standard tool or a clever combination of them doing the same thing.

So we all have the diff command installed by default. I certainly don't know how to use it *well*. But I would expect some reasonable default usage. Yet when I type diff file1 file2 I get ... a text ... which I have to parse in my head ... which is not helped by the fact that this is a weird combination of two texts, which are in turn very complex themselves. So I looked for a graphical solution, e.g. meld. That works much much better out of the box. Yet I would prefer to have the luxury of staying on the command line all the time. Is there a fairly standard command which: - uses colour by default and can adopt syntax highlighting - presents side-by-side diffs and does 3-way merges by default - works on the command line, e.g. via libncurses - depends on neither vim, emacs nor an IDE - can modify edited files in place? If not, why not? I looked into colordiff but it doesn't quite cut it.

Ok so the situation is that I have an unknown number of sub-directories that all follow the same naming profile folder0, folder1, folder2, folder3 etc Now each folder will have 3 text files and these text files will have the same 3 file names in all folders file1 file2 file3 I would like to find an easy way to concatenate all the text files in all the folders into one text file, starting in folder0 with file1, then file2, then file3 and the same order in all folders. Now for a small number of folders I could use cat cat folder0/file1 folder0/file2 folder0/file3 folder1/file1 folder1/file2 folder1/file3 folder2/file1 folder2/file2 folder2/file3 folder3/file1 folder3/file2 folder3/file3 > textfile but the number of folders is unknown and could range into the 100's or 1000's anybody have any indea of a script that would acomplish this.

I have folders arranged as such:

Directory
-Subdirectory A 1
--Subdirectory B 1
--Subdirectory B 2
-Subdirectory A 2
--Subdirectory B 3
--Subdirectory B 4

How do I merge all the Subdirectory As into one folder without also merging the Subdirectory Bs?

I need to merge a few dozed pdfs, and i want all of the input pdfs to start on an odd page in the output pdf. Example: A.pdf has 3 pages, B.pdf has 4 pages. I _don't want_ my output to have 7 pages. What I want is an 8-page pdf in which pages 1-3 are from A.pdf, page 4 is empty, and pages 5-8 are from B.pdf. How can I do this? I know about pdftk, but I didn't find such an option in the man page.

I have multiple folders with a lot of files, Each folder has txt files of the same name, I want to merge files with the same name into one txt file. Example:

folder/
     -sub1
     -sub2
     -sub3
      .
      .
      .
     -sub28

In each subfolder has a multiple files:

EAF001.ID001.txt  EAF001.ID002.txt  EAF001.ID003.txt  EAF001.ID004.txt
EAF001.ID005.txt  EAF001.ID006.txt  EAF001.ID007.txt  EAF001.ID008.txt
EAF001.ID009.txt  EAF001.ID010.txt  EAF001.ID011.txt  EAF001.ID012.txt
EAF001.ID013.txt  EAF001.ID014.txt  EAF001.ID015.txt  EAF001.ID016.txt

I want merge files with the same name.

EAF001.ID001.merge.txt  EAF001.ID002.merge.txt  EAF001.ID003.merge.txt  EAF001.ID004.merge.txt
EAF001.ID005.merge.txt  EAF001.ID006.merge.txt  EAF001.ID007.merge.txt  EAF001.ID008.merge.txt
EAF001.ID009.merge.txt  EAF001.ID010.merge.txt  EAF001.ID011.merge.txt  EAF001.ID012.merge.txt
EAF001.ID013.merge.txt  EAF001.ID014.merge.txt  EAF001.ID015.merge.txt  EAF001.ID016.merge.txt

Any help would be much appreciated.

I have 2 JSON files with arrays (extracted from restAPI using curl in bash). Both files are arrays with a .result object at the top which needs to remain. The first has a .name field and many (over 100) other fields including .ip_address which is blank. The second has additional information like interface and ip address and the name (key) in a different field name. The key in the first file is not the same as the key in the second but should be related (I could change the key field name of course before and the key's data is often mixed case) I want to merge them so that the first JSON's ip_address is overwritten where the .name fields are the same and the additional data added: I get that it's either multiplying the arrays or reducing and adding but I can't get it right based on the examples already found. For a solution, I would be most grateful. **Servers:** { "result": [ { "os": "Microsoft Windows Server 2019 Standard", "name": "SERVER1", "ip_address": "" }, { "os": "Microsoft Windows Server 2019 Standard", "name": "SERVER2", "ip_address": "" }, { "os": "Microsoft Windows Server 2019 Standard", "name": "server3", "ip_address": "" }, { "os": "Microsoft Windows Server 2016 Standard", "name": "server4", "ip_address": "" } ] } **ips.txt** { "result": [ { "interface": "Intel Wireless-AC 9560 160MHz", "cmdb.name": "server1", "ip_address": "10.0.0.10" }, { "interface": "Wi-Fi", "cmdb.name": "server2", "ip_address": "10.0.0.10" }, { "interface": "Intel Dual Band Wireless-AC 8265", "cmdb.name": "server4", "ip_address": "10.0.0.10" } ] } **Desired output of Server data is:** { "result": [ { "os": "Microsoft Windows Server 2019 Standard", "name": "SERVER1", "interface": "Intel Wireless-AC 9560 160MHz", "ip_address": "10.0.0.10" }, { "os": "Microsoft Windows Server 2019 Standard", "name": "SERVER2", "interface": "Wi-Fi", "ip_address": "10.0.0.10" }, { "os": "Microsoft Windows Server 2019 Standard", "name": "server3", "ip_address": "" }, { "os": "Microsoft Windows Server 2016 Standard", "name": "server4", "interface": "Intel Dual Band Wireless-AC 8265", "ip_address": "10.0.0.10" } ] }

I have two text files 1.txt and 2.txt that contain two tab separated columns. The first column of both files consists of tokenized text. In both files, the first column is the same. The word order matters. The second column consists of tags. In the first file, the tokenization is complete but imprecise. In the second file, it is incomplete but precise. 1.txt:

I          3
was        5
there      6
yesterday  6
.          0

2.txt:

I          3
was        
there      12
yesterday  
.          0

I want to merge these two files (while maintaining the order of the lines) so that there is a tag on each line and so the more precise (i.e. the tags from file 2.txt) are preferred as follows:

I          3
was        5
there      12
yesterday  6
.          0

---------- I've tried using join, but it can display only both of the tags or just the tags from one file:

$ join 1.txt 2.txt 
I          3 3
was        5 
there      6 12
yesterday  6 
.          0 0
$ join -1 1 -2 1 -o 1.1,2.2 1.txt 2.txt
I          3
was        
there      12
yesterday  
.          0

[This answer](https://unix.stackexchange.com/a/612064/526245) using awk seems close but doesn't deliver the desired result. I'd also prefer using coreutils.
