I have a file in the form of: XXX XXXX XXX-6VwvOkZvzuI.description How can I get just the file name XXX XXXX XXX? I've tried: for file in $(ls .d*) do fname="${file%*-}" ext="${filename%.*}" done

When I apply [dir](https://www.gnu.org/software/make/manual/make.html#index-dir) to a list of files, it adds additional directories. For example, with the following file/directory structure:

.
├── a
│   └── foo.c
├── b
│   └── foo.c
├── c
│   └── foo.c
├── d
├── Makefile
└── readme.md

and this Makefile:

FILES=*/foo.c
DIRS=$(dir */foo.c)

all:
    @echo $(FILES)
    @echo $(dir $(FILES))
    @echo $(DIRS)

running make results in the following output:

a/foo.c b/foo.c c/foo.c
a/ b/ c/ d/
a/ b/ c/ d/

Why is the directory d added to the list? The [definition](https://www.gnu.org/software/make/manual/make.html#index-dir) of $(dir names) says > Extracts the directory-part of each file name in names. Thus, I expect $(dir $(FILES)) or $(dir */foo.c) to be only a/ b/ c/, that is, the directories where the foo.c files reside in. I am using GNU Make 4.4.1.

Epson has a printer driver that is open source called [ESCPR](https://support.epson.net/linux/Printer/LSB_distribution_pages/en/escpr.php) . This driver only supports printers up to a certain year. Newer printers are not supported by this driver. They've since ditched that one and created another driver called [ESCPR2](https://support.epson.net/linux/Printer/LSB_distribution_pages/en/escpr2.php) but this only contains partial source code, some files are pre-compiled static libraries (.a). [Here is the direct driver download link to the ESCPR2 "source".](https://download3.ebz.epson.net/dsc/f/03/00/17/28/09/4e8dc40219d4b52e414b608de92552af4fd46eca/epson-inkjet-printer-escpr2-1.2.35-1.tar.gz) There's an AUTHORS file with the email: > Seiko Epson Corporation What's the best way to ask for the source code of their newer ESCPR2 driver?

I'm trying to install Linux 10.04 so I can use an old piece of hardware (an audio interface) but I'm getting an error. I added the log file to the following paste bin: https://pastebin.com/33dp5AuG Does it have something to do with the squashfs file not being found?

I have installed Kali in VirtualBox and now trying to install Guest Additions to get full screen view. I updated and installed my packages and installed dkms. When I try to install linux-headers I get the following: # apt-get install linux-headers-$(uname -r) Reading package lists... Done Building dependency tree Reading state information... Done linux-headers-4.14.0-kali1-amd64 is already the newest version (4.14.2-1kali1). 0 upgraded, 0 newly installed, 0 to remove and 86 not upgraded. The headers installed are as follows: # dpkg --get-selections | grep linux-headers linux-headers-4.14.0-kali1-amd64 install linux-headers-4.14.0-kali1-common install linux-headers-amd64 install When I try to run the Guest Additions CD I get the following: Verifying archive integrity...

I defined a new samba mount in an ubuntu VM via /etc/fstab

//x.x.x.x/share  /share  cifs  credentials=/.smbcreds,uid=1000,gid=1000,vers=3.0  0  0

With this I get the following output from df -h

filesystem       Size   Used  Avail  Use%  Mounted On
//x.x.x.x/share  5.0G   79M   5.0G   2%    /share
...

This is a ZFS share on the host and I am using samba to expose it here. I would expect to see about 12TB of free space, which is what I see if I run df -u on the samba host. Running du -f --max-depth=1 in the ubuntu VM reports this:

2.2T   /share
...

Which is the correct usage for the mount. Ultimately I am having issues where services are trying to write files to the mount that are larger than the total reported filesystem space and they fail since they do a check on available space before writing.

Virt Manager configuration: Guest memory usage right after booting (nothing is running): I'm running virt-manager on a standard Ubuntu 17.10 system. In Proxmox, the same general configuration (with ballooning enabled) would allocate 8GB of the host but the guest would have roughly 1-2GB used out of 16GB instead of this. I'm pretty sure I have all the guest drivers installed. (qemu guest, virtio stuff, balloon driver & service) This is not my first QEMU VM, but the only one outside of Proxmox (which I'm assuming does some extra stuff that virt-manager doesn't). What really exacerbates this issue is if I set the **Current allocation** to 2GB, the guest has about 15.6GB compressed and most software won't launch or run correctly because there's no free system memory... ---------- Host: :~$ free -m total used free shared buff/cache available Mem: 32163 20273 8949 176 2940 11325 Swap: 2047 2 2045 Hardly anything is running on the host. It looks like the entire 16GB is getting claimed but simultaneously most of that memory is inaccessible to the guest.

I'm running Ubuntu 20.04 on my laptop and today it suddenly started freezing up frequently for seconds on end. When I check the running processes it seems that a process called "upowerd" is hogging up the CPU causing lag spikes rendering my system useless. I tried disabling this service and killing the process hoping to fix it but it keeps starting again. Note, I don't have an iPhone, I have a mouse and a keyboard connected through USB and an external monitor connected through HDMI. My laptops battery is pretty much dead so I always use it connected to the power. Any help is appreciated as I'm not able to play any games or even properly use my laptop anymore. Please let me know if there are any extra info I can provide to help debug the issue. Thanks in advance.

For many years, my system's \home partition has always been able to be mounted normally after the system starts. Every time I shut down, I will use the shutdown command to shut down,thereforce,there are almost any issues,but now for unknown reason,the system has entered Emergency Mode|Control-D Error and I can no longer enter the system desktop normally.

So, I set up another FreeBSD server. Everything was ok until I tried to connect to it via my old FreeBSD. On connection it echoes:

Unable to connect to relay host, errno=61
ssh_exchange_identification: Connection closed by remote host

But I just used Putty to connect to it and it works. On top of it, I had connected to my old via SSH with no problem. It still can't connect to new one. **TL;DR:** SSH * Win->Old = ok * Win->New = ok * New->Old = ok * Old->New = *no_go* What am I doing wrong?

Ok, this is driving me crazy. I'm setting up an old Dell Precision M60 notebook, and I can't manage to enable support for its wireless device on debian squeeze. What I tried: lspci | grep -i wireless 02:03.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 02) nice. I found this page on debianwiki: bcm43xx .

Back to the debianwiki page " For 802.11b-only devices (BCM4301) or **802.11b/g devices with the BCM4306 revision 2 chipset, install firmware-b43legacy-installer**" let's try: sudo aptitude install firmware-b43legacy-installer .. firmware-b43legacy-installer E: Sub-process /usr/bin/dpkg returned an error code (1) A package failed to install.

I have a NFS4 share running with krb5p. I have no problems accessing it from CentOS clients, all that is required is: yum install krb5-workstation setup krb5 (edit krb5.conf, setup keytab) systemctl enable nfs-secure.service && systemctl start nfs-secure.service systemctl enable nfs-client.target && systemctl start nfs-client.target mkdir /mnt/x Add the following to fstab: server.example.com:/srv/share/subdir /mnt/x nfs4 defaults,sec=krb5p,noexec,nosuid,_netdev,auto 0 0 This works great on CentOS, I've setup a dozen client hosts so far that way. However on Ubuntu, I get : mount.nfs4: an incorrect mount option was specified I think the Ubuntu error is to do with nfs-secure.service however there seems to be no equivalent on Ubuntu that gets installed with NFS client ? (I am using Ubuntu 16.04.5 LTS). ***UPDATE:*** I have tried: systemctl enable rpc-gssd.service && systemctl start rpc-gssd.service That launches OK: # systemctl status rpc-gssd.service ● rpc-gssd.service - RPC security service for NFS client and server Loaded: loaded (/lib/systemd/system/rpc-gssd.service; static; vendor preset: enabled) Active: active (running) since Thu 2018-10-04 16:49:40 BST; 6min ago Process: 51689 ExecStart=/usr/sbin/rpc.gssd $GSSDARGS (code=exited, status=0/SUCCESS) Main PID: 51691 (rpc.gssd) Tasks: 1 Memory: 516.0K CPU: 13ms CGroup: /system.slice/rpc-gssd.service └─51691 /usr/sbin/rpc.gssd But Ubuntu just hangs when trying to mount ? # mount -v -t nfs4 -o defaults,sec=krb5p,noexec,nosuid,_netdev,auto server.example.com:/srv/dir/example /mnt/example mount.nfs4: timeout set for Thu Oct 4 16:54:40 2018 mount.nfs4: trying text-based options 'sec=krb5p,addr=10.10.10.10,clientaddr=10.10.10.9' # NOTHING ELSE HAPPENS.....

I have a rather weird and repeatable issue. I have 3 pi's, left, right, and base. The left and right have cameras and perform computer vision. They regularly send UDP packets to the base. The program that sends these packets is started by a service. When I reboot everything the base starts receiving packets from left, but not right. The base can ping both of them with low latency. So now I try to ssh into right to see what's happening (left and right are both headless). For some reason as soon as I ssh into right, it immediately starts working. I've done this over and over and it is repeatable. Previously I was unable to ssh into the right because it perpetually said "booting try again later" or something like that. I fixed this by disabling pam_nologin.so. I think a service was failing and holding up the boot. So my best guess is that a service is still hanging and holding up the computer vision service (or maybe that's the one hanging). Then for some reason when I ssh in, it un-hangs, or aborts or something. All pi's are running raspbian buster. What is going on here? What are some steps I can use to narrow it down? **Edit:** As grawity suggested I saved the output of journalctl -b It seems as though the computer vision program doesn't even try to run at boot. I waited about 4 minutes and then SSH'd in, just so there would be a clear break in the logs.

I'm not a linux expert, but it seems like the user under which the service runs is not "started" until I ssh in. I'm not sure how to fix that. I do have linger enabled for user pi. I also noticed that the working raspberry pi has Machine model: Raspberry Pi 4 Model B Rev 1.4, whereas the non-working on has Machine model: Raspberry Pi 4 Model B Rev 1.2

I am using Debian Trixie on a server. I have installed it using ZFSBootMenu [documentation](https://docs.zfsbootmenu.org/en/v3.0.x/guides/debian/uefi.html) , without a desktop environment.

My hostname is configured correctly (I think, I have done systemctl set-hostname servername). /etc/hosts:

I have installed avahi and avahi works (ping servername.local works) but reverse DNS still does not work. I have tried to specify the hostname in /etc/dhcpcd.conf, changed from duid to clientid, delete leases, rebooted, but no improvement. I would like to get dhcpcd to work because it is the default one that came when I installed Debian Trixie. I think the Raspberry pi official Linux also use (used?) dhcpcd and has reverse DNS working, so this should be possible.

I have a Linux/Windows dual boot setup on my notebook, in which I used to keep most of the data on the Windows partition to be able to access it from both systems. Since I almost never use Windows I shrunk the NTFS partition and plan to move the data to the Linux partition which is formatted as btrfs. Beforehand the btrfs partition needs to be expanded at the beginning where the now free space is. fdisk can move the beginning of a partition but leaves the filesystem untouched. parted cannot handle the filesystem, either, since version 3.0. One solution to the problem would be to create a partition in the free space and add it as a backing device to the btrfs, then removing the original btrfs from btrfs (using btrfs device) and the partition table and after that expanding the remaining btrfs+partition to the end of the drive. The problems here are that the new free space must be big enough to hold all the files from the btrfs and that all the data has to be moved. So my question is: Is there some other, preferably more elegant and generally applicable, way to expand a btrfs at the beginning? ***Edit: (Solution)*** Even if GParted might be able to resize at the beginning by automatically moving the filesystem, I tried the way described above since I have the free space. As it took ages (perhaps because of many subvolumes), used many cpu and I/O resources and then aborted with an I/O error, I used btrfs replace instead which worked just fine: It took a few hours during which the computer was perfectly usable.

Consider this one-liner bash example:

$  (function test() { echo "testing a string" | grep "a" | sed 's/i/y/g'; }; set -x; test | grep "test" )
+ grep --color=auto test
+ test
+ grep --color=auto a
+ sed s/i/y/g
+ echo 'testing a string'
testyng a stryng

The "main" command line after the set -x here is test | grep "test"; could I somehow set up bash to only log the "main" command lines? In this case I'd simply want the printout

+ test | grep "test"
testyng a stryng

I tried installing "libgtk2.0-dev" with below command. But it failed with yum install libgtk2.0-dev Error "No package libgtk2.0-dev available" There are many posts related to this issue but none works out as no post covered this issue in entirety example: One Post recommended to follow below steps. I tried it but of no avail yum groupinstall "Development Tools" yum install gtk+-devel gtk2-devel I am using "Red Hat Enterprise Linux Server release 5.3 (Tikanga)". Can someone help with steps to install this library ( in plain english as I have never installed one )

I use xen with a buildroot on the CPU0 and a baremetal written in C on the CPU1. The arch is ARM64. The shared mem works with 1k of pages (an array of 4096 values). I am trying to send data from the linux to the baremetal and the opposite. I have written this code : Linux : #define BUFF_SIZE 4096 #define ITERATIONS 10000 volatile char *memory = (volatile char *)xc_map_foreign_range(xc, domainid, 0x1000, PROT_WRITE | PROT_READ, (unsigned long) 40000000 >>12); uint8_t *local_buf = malloc(BUF_SIZE); memset(local_buf, 0xAB, BUF_SIZE); int i; double start = now(); memory = 0; for (i = 0; i < ITERATIONS; i++) { memcpy(memory+1, local_buf, BUF_SIZE-1); truc = 1; while (memory) __asm__ volatile("yield"); } double end = now(); double elapsed = end - start; double total_bytes = (double)BUF_SIZE * 1 * ITERATIONS; // écriture + lecture double mbps = (total_bytes / elapsed) / (1024.0 * 1024.0); printf("%.2f MB in %.3f sec = %.2f MB/s\n", total_bytes / (1024.0 * 1024.0), elapsed, mbps); Baremetal : uint8_t *local = (uint8_t *) malloc(sizeof(uint8_t) * 0x1000); volatile char *tmp = (uint8_t *) (BUF+0); for (;;) { if (tmp == 1) { memcpy(local, (uint8_t *) tmp+1, 0x10000-4); tmp = 0; } } I know, this is archaic ! My problem is the sync method, but with a baremetal I don't know if an other method is possible. More than 2G/s without sync but 200K/s with. I must have 5M/s at least. I tried to use the event libs from xen but my project is complex and includes a lot of libs from xilinx. What other method exists? --- edit --- I want to send ip packets with latency less than 10 ms because I will have video and audio data. Max size is 4096 bytes per packets but most of time it should be around 1500 bytes because of MTU.
