in Debian-based systems apt-get could be limited to the specified bandwidth in kilobytes using the apt configuration options(man 5 apt.conf, man apt-get). I'd quote man 5 apt.conf: "The used bandwidth can be limited with Acquire::http::Dl-Limit which accepts integer values in kilobyte. The default value is 0 which deactivates the limit and tries uses as much as possible of the bandwidth..." "HTTPS URIs. Cache-control, Timeout, AllowRedirect, Dl-Limit and proxy options are the same as for http..."
2sudo apt-get -o Acquire::http::Dl-Limit=20 -o Acquire::https::Dl-Limit=20 upgrade -y -
After, check if working by executing this command locally : git clone git@192.168.0.18:repositories/gitosis-admin.git Tutorial : http://blog.hemca.com/?p=560

A little aptitude magic. Note: this will remove images AND headers. If you just want to remove images: aptitude remove ?and(~i~nlinux-im ?not(~n`uname -r`)) I used this in zsh without any problems. I'm not sure how other shells will interpret some of the special characters used in the aptitude search terms. Use -s to simulate.
2aptitude remove ?and(~i~nlinux-(im|he) ?not(~n`uname -r`)) -
In my case it was actually like this... Show Sample Output
2cat /proc/acpi/ac_adapter/AC0/state -
Change the APP variable's value to whatever you want to install. Depending on how fast your machine is, you'll want to adjust the value 50 to something else. You might also want to play a different game than Gnometris - just make sure it's a GUI game.
2APP=wine; if [ $(sudo apt-get --print-uris -y install $APP | sed -ne 's/^After this operation, \([0-9]\{1,\}\).*MB.*/\1/p') -gt 50 ]; then gnometris 2>/dev/null & sudo apt-get install $APP; else sudo apt-get install $APP; fi -
2sudo deborphan | xargs sudo apt-get -y remove --purge

2aptitude search '~i!~E' | grep -v "i A" | cut -d " " -f 4

Debian: Mark all dependent packages as manually installed. So they are not automatically removed if you remove some meta package - like gnome-desktop-environment for example.
2sudo aptitude unmarkauto $(apt-cache depends some-deb-meta-package-name | grep Depends | cut -d: -f2) -
when we add a new package to a aptitude (the debian package manager) we need to add the gpg, otherwise it will show warning / error for missing key Show Sample Output
2wget -q http://xyz.gpg -O- | sudo apt-key add - -
This is useful if you add sid, install some packages, then remove sid and want to work out which packages you installed from sid that should be removed (e.g. before an upgrade to the new stable). Alternatively you can think of this as "find installed packages that can no longer be installed."
1aptitude search -F '%p %v %V %O' '?narrow(?not(?archive("^[^n][^o].*$")),?version(CURRENT))' | while IFS=' ' read -r pkg ver candidate origin; do if [[ $ver == "$candidate" ]] && [[ $origin == '(installed locally)' ]]; then echo "$pkg"; fi; done -
Sometimes we install programs, we forget about them, and they stay there wasting RAM. This one-liner try to find them. Show Sample Output
1ps -eo cmd | awk '{print $1}'| sort -u | grep "^/" | xargs dpkg -S 2>/dev/null | awk -F: '{print $1}' | sort -u | xargs apt-mark showmanual -
This will also work with bash instead of sh shell sudo bash -c 'apt update -y && apt upgrade -y'

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
1apt purge linux*{14..18}* -
it's nice to be able to use the command `ls program.{h,c,cpp}`. This expands to `ls program.h program.c program.cpp`. Note: This is a text expansion, not a shell wildcard type expansion that looks at matching file names to calculate the expansion. More details at http://www.linuxjournal.com/content/bash-brace-expansion I often run multiple commands (like apt-get) one after the other with different subcommands. Just for fun this wraps the whole thing into a single line that uses brace expansion.
1echo apt-get\ {update,-y\ upgrade}\ \&\& true | sudo bash -
1sudo apt-get remove --purge $(dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d')

Cleans apt-get and gpg cache and keys
1sudo gpg --refresh-keys; sudo apt-key update; sudo rm -rf /var/lib/apt/{lists,lists.old}; sudo mkdir -p /var/lib/apt/lists/partial; sudo apt-get clean all; sudo apt-get update -
Could be dangerous, if you have many packages all beginning with 'foo' or 'bar'. This will easily remove them all from your system.
1aptitude --purge remove ~i^foo ~i^bar -
In this case, linux- is the prefix; simply running
apt-cache pkgnameswould 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 Output1apt-cache pkgnames linux- -
1wget -r -P ./dl/ -A jpg,jpeg http://captivates.com

Sort netflow packet capture by unique connections excluding source port. Show Sample Output

Replace KEY with GPG key. This command will load GPG key and add it to your system so you can use software from third party repos etc. Show Sample Output
1x=KEY; gpg --keyserver subkeys.pgp.net --recv $x; gpg --export --armor $x | sudo apt-key add - - < 1 2 3 4 5 > Last ›
