Get status of LXC

This short snippet outputs the state of all containers available on your system. It is quite helpful to see which ones are running and which are stopped. Please notice that the "sort -u" is needed, otherwise running containers will be reported twice (see output of "lxc-ls" on its own for why) Show Sample Output

Unmount all mounted SAMBA/Windows shares

This is a handy command to put into ~/.bash_logout to automatically un-mount windows shares whenever the user logs out. If you use this on as a non-root account then you'll need to append sudo before umount and the user will need to have the appropriate sudoer rights to run the /bin/umount command.

Across an entire subtree, list not-empty directories that have no child-directories, globally sorted by their respective mtime

This let me find some a set of modifications that were made to a rather large tree of files, where the file-names themselves were not unique (actually: insanely redundant and useless. "1.dat 2.dat ..."). Pruning down to last-branch brough things back to the "project-name" scope, and it's then easy to see which branches of the tree have recently changed, or any other similar search. Ideally, it should sort the directories by the mtime of the most recent *file* *inside* the directory, but that's probably outside the scope of a (sane...) command line.

What's this?

commandlinefu.com 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.

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"

Avoiding history file to be overwritten

If histappend options is set in bash, the file .bash_history will not be overwrite and history list is append to it.

Print every Nth line

Sometimes commands give you too much feedback. Perhaps 1/100th might be enough. If so, every() is for you. $ my_verbose_command | every 100 will print every 100th line of output. Specifically, it will print lines 100, 200, 300, etc If you use a negative argument it will print the *first* of a block, $ my_verbose_command | every -100 It will print lines 1, 101, 201, 301, etc The function wraps up this useful sed snippet: $ ... | sed -n '0~100p' don't print anything by default $ sed -n starting at line 0, then every hundred lines ( ~100 ) print. $ '0~100p' There's also some bash magic to test if the number is negative: we want character 0, length 1, of variable N. $ ${N:0:1} If it *is* negative, strip off the first character ${N:1} is character 1 onwards (second actual character).

Command to logout all the users in one command

This command logs out all users - which is way more secure to use ps -ef and "grep" to kill processes. Never ever use ps -ef piped to grep to kill something. If you ever need to ps-something use the UNIX95-directive, which makes sure you will never need "grep" together with "ps".

Add "prefix" on a buch of files

Tweak system files without invoking a root shell

only for sudo-style systems. Use this construct instead of I/O re-directors ``>'' or ``>>'' because sudo only elevates the commands and *not* the re-directors. ***warning: remember that the `tee` command will clobber file contents unless it is given the ``-a'' argument Also, for extra security, the "left" command is still run unprivileged.

Grep colorized
