Commands using apt (48)

  • That command installs "most" and make this command as the default man reader. The "most" works like "less" (the current man reader), but it render colors for manpages and may do more things. Read "man most". You can see a preview here:

    apt-get install most && update-alternatives --set pager /usr/bin/most

  • Shows all configurations to apt and dpkg, rarely changed, you probably still have the default configuration. Go ahead and explore your configuration if you dare, perhaps change your apt-cache directory, Dir::Cache "var/cache/apt/"; or the names of the log files. Show Sample Output

  • This will take the packages matching a given `apt-cache search` query (a collection of AND'd words or regexps) and tell you how popular they are. This is particularly nice for those times you have to figure out which solution to use for e.g. a PDF reader or a VNC client. Substitute "" for "" if you want this to use Ubuntu's data instead. Everything else will work perfectly. Show Sample Output

    apt-popcon() { (echo \#rank; apt-cache search "$@" |awk '$1 !~ /^lib/ {print " "$1" "}') |grep -Ff- <(wget -qqO- |gunzip); }

  • if you don't want to show string "version?, then use awk or cut filter it: apt-cache show pkgname | grep -i "version:" | awk '{ print $2 }' we can also use regex to search many packages and show their versions: apt-cache search pkgregex | grep -i "version:" Show Sample Output

    apt-cache show pkgname | grep -i "version:"

  • This let's you find out the total packages that have available upgrades. Usefull if you want to check or show the total available upgrades on your system. Show Sample Output

  • After, check if working by executing this command locally : git clone git@ Tutorial :

    apt-get -y install git-core gitosis; adduser --home /home/git --gecos "git user" git; su git -c "ssh-keygen -t rsa -f /home/git/.ssh/id_rsa; gitosis-init < ~/.ssh/id_rsa"

  • An apt-get wrapper function which will run the command via sudo, but will run it normally if you're only downloading source files. This was a bit of an excuse to show off the framework of cmd && echo true || echo false ...but as you can see, you must be careful about what is in the "true" block to make sure it executes without error, otherwise the "false" block will be executed. To allow the apt-get return code to pass through, you need to use a more normal if/else block: apt-get () { if [ "$1" = source ]; then command apt-get "$@"; else sudo apt-get "$@"; fi }

    apt-get () { [ "$1" = source ] && (command apt-get "$@";true) || sudo apt-get "$@" }

  • Taken from apticron and modified. Show Sample Output

  • Usefull if you only want to see the package names, or if you want to use them in a script.

    apt-get -s upgrade | awk '/Inst.+/ {print $2}'

  • In this case, linux- is the prefix; simply running apt-cache pkgnames would list every package APT knows about. The default APT config assumes -g, --generate; to use the cache as/is, you could similarly run: apt-cache --no-generate pkgnames [prefix] Adding --all-names, like so: apt-cache --no-generate --all-names pkgnames [prefix] would print all the packages APT knows about, using the cache as/is, including virtual packages and missing dependencies. This command was shamelessly stolen from the apt-cache(8) man-page. Show Sample Output

    apt-cache pkgnames linux-

  • An alternative without aptitude.

  • If, for example, you want to remove all kernels and headers but the last three versions, you can't use one of that magic all-in-one "remove old stuff" commands. With this simple but elegant command you can remove a range of versions, or a list of versions with e.g. {14,16,20}. Show Sample Output

    apt purge linux*{14..18}*

What's this? is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

easily find megabyte eating files or directories
This is easy to type if you are looking for a few (hundred) "missing" megabytes (and don't mind the occasional K slipping in)... A variation without false positives and also finding gigabytes (but - depending on your keyboard setup - more painful to type): $du -hs *|grep -P '^(\d|,)+(M|G)'|sort -n (NOTE: you might want to replace the ',' according to your locale!) Don't forget that you can modify the globbing as needed! (e.g. '.[^\.]* *' to include hidden files and directories (w/ bash)) in its core similar to:

Create more threads with less stack space
default stack size is 10M. This makes your multithread app filling rapidly your memory. on my PC I was able to create only 300thread with default stack size. Lower the default stack size to the one effectively used by your threads, let you create more. ex. putting 64k I was able to create more than 10.000threads. Obviously ...your thread shouldn't need more than 64k ram!!!

Multi-segment file downloading with lftp
This is for files only, for directories 'mirror' has to be used.

Substitute audio track of video file using mencoder
Creates a new video file with video stream copied from input file and a different audio stream

Cut/Copy everything arround brackets or parentheses on vim (in normal mode)
Put the cursor on either curly braces ( {, } ). Then press d% The d is delete command, and % is movement command that move the cursor to another matching parentheses (or curly braces in this case). This action will delete every character that was on the way of the movement (from the first curly braces to the second).

List programs with open ports and connections
I prefer to use this and not the -n variety, so I get DNS-resolved hostnames. Nice when I'm trying to figure out who's got that port open.

show git logging
shows some logging for the git repo.

Set laptop display brightness
Run as root. Path may vary depending on laptop model and video card (this was tested on an Acer laptop with ATI HD3200 video). $ cat /proc/acpi/video/VGA/LCD/brightness to discover the possible values for your display.

Detect illegal access to kernel space, potentially useful for Meltdown detection
Based on capsule8 agent examples, not rigorously tested

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
