file <filename>
2011-11-19 23:39:29
User: lordtoran
Functions: file

Some shell newbies don't know this very handy file management related command so I decided to include it here.

You need to have the "file" package installed.

ls | xargs -I{} du -sh {}
<CTRL+Z>; fg
2014-04-06 14:21:08
User: kbrotheridge

Saves opening another console terminal (eg. CTRL+ALT+F[n]) or opening another remote terminal.

Ctrl+Z pauses the current task and pushed it to the background, leaving you with a command prompt for those "Oh crap I forgot to change xyz before I ran that and it'll take forever if I Ctrl+C and start again..." situations. Typing 'fg' (shorthand for foreground, that's how I remember it) will resume the paused task.

Bash scrip to test if a server is up, you can use this before wget'ing a file to make sure a blank one isn't downloaded.

for i in *.wma; do mplayer -vo null -vc dummy -af resample=44100 -ao pcm:waveheader:file="${i%.wma}.wav" "$i" ; done

I wanted to play a song from the shell and get the shell back, I also dont want to store the file if it is not needed.

edit, not sure if I need to mention it... killall vlc to stop it

slow () { [ -n $1 ] && while kill -STOP $1; do sleep 1; kill -CONT $1; sleep 1; done }

User: makidoko
Functions: kill sleep
Tags: io

compare to alternative :

- directly tests the -STOP of the process to continue or stop loop,

- background operator should be set (or not) at the call of the function

For extension i suggest a slowPID() based on kill like above and a slowCMD based on killall.

PLAYLIST=$(ls -1) ; mpg123 -C $PLAYLIST
2009-03-19 17:20:28
Functions: ls mpg123

On my music directory, I create variable that contains all mp3s files, then I play them with mpg123. -C options enable terminal control key, s for stop, p for pause, f for forward to next song.

Functions: find rmdir tac xargs

Remove all empty directories below the current directory. If directories become empty as the results of this, remove those too.

host foo.com|grep " has address "|cut -d" " -f4
2010-10-29 17:01:37
User: dinomite
Functions: cut grep host

Get just the IP address for a given hostname. For best results, make this a function in your shell rc file so that it can be used for things like traceroute:

Titus:~$ traceroute `getip foo.com`

traceroute to (, 64 hops max, 52 byte packets

Functions: awk find wc
Tags: awk find wc

Have wc work on each file then add up the total with awk; get a 43% speed increase on RHEL over using "-exec cat|wc -l" and a 67% increase on my Ubuntu laptop (this is with 10MB of data in 767 files).

By default, slot 1 is used for OTP purposes and validates against the Yubikey servers. Running the command above will replace that. If you have a Yubikey 2 or above, you can change -1 to -2 and program the second slot with a strong static key.

When you press "cmd+n" in TextMate, you can have "HTML" language as default document format... You can also define other languages too. You need to know the UUID of your language bundle.

2010-05-18 14:49:44

Functions: grep sort tr

1.) my profile ends with $USER not with .default

2.) only grep for the first occurrence because some extensions have the translated name also inside the install.rdf

Functions: awk cut sed

This is an easy way to quickly get a status for a device in multipath on SLES systems, as long as the server is configured based on Novell's standards, where multipathed disks are referred to by /dev/disk/by-... tree. Make sure to replace name_of_vg with your Volume Group name.

In MySQL client, \P less -S
2011-01-19 09:44:43
User: maxmanders
Functions: less

Instead of dumping the entire query to the screen, it will use 'less -S' to handle pagination. This means you can move back and forward through the result set, and instead of wrapping rows at screen boundaries, the table will extend off the screen, and can be scrolled left and right with arrow keys.

1. Get name of task by task=$(basename "$(pwd)")

2. Check whether "$task.c" exists as a file

3. open "$task.c", "$task.in", "task.out" in vim with such layout.
