Displays time of last system boot

Report memory and swap space utilization statistics e.g. memory free/used, swap free/used

Send signal 0 to the process. The return status ($?) can be used to determine if the process is running. 0 if it is, non-zero otherwise.

Where foodir is the directory you want to zip up.

You only have to fill in your administrative account and password, and the router FQDN!

I recommand to execute this command not over the internet, because there is no encryption (the username and password will be transmitted in plaintext!)

VARNAMES='ID FORENAME LASTNAME ADDRESS CITY PHONE MOBILE MAIL ...'

cat customer.csv | while read LINE ; do

COUNT=1

for VAR in $VARNAMES ; do

eval "${VAR}=`echo $LINE | /usr/bin/awk {'print $'$COUNT''}`"

let COUNT=COUNT+1

done

done

Maybe you have a CSV-File with addresses, where you have to process each contact (one per line, write each value to own variable). Of course you can define every variable, but this way is more simple and faster (to write).

VARNAMES includes the variable names. Pay attention: the number of names in VARNAMES have to be the same than in the CSV-file the fields. If the CSV is not seperated with ";", you can set the seperator after the awk-binary with -F"_" for example.

Deletes empty directories and prints an error if directory is not empty.

Returns tomorrow's date in the format yyyyMMdd

Assumes you have ffmpeg and oggenc.

Similar to other scripts here, but this time outputting to Ogg Vorbis.

I added the variable assignment for a nice output name.

The uuencode utility will encode your file so that it can be sent as an attachment to an email. It is part of the sharutils package in RHEL/CentOS/Fedora.

Note, this works because smtp is running

I used an flv in my example, but it'll work on any file ffmpeg supports. It says it wants an output file, but it tells what you want to know without one.

This converts all m4a files in a dir to flv. You can just swap the m4a bit to anything else ffmpeg supports though, and it'll work.

This is handy for making screenshots of all your videos for referring to in your flv player.

Important to know: a valid date will return 0, otherwise 1!

Suspends all Firefox Threads. Results in Zero CPU load.

Useful when having 100+ Tabs open and you temporarily need the power elsewhere.

Be careful - might produce RACE CONDITIONS or LOCKUPS in other processes or FF itself.

matching is case sensitive.

It prints myvideo.srt subtitle files in myvideo.avi, saving it in myvideo_subtitled.avi

This will record the capture channel of your soundcard, directly encoded in Ogg Vorbis, in stereo at quality 5 (I'm using this to record live jam sessions from my line input). You can choose which device to capture (eg. line input, microphone or PCM output) with

You can do the same thing and live encode in MP3 or FLAC if you wish, just check FLAC and LAME man pages.

Based on linkinpark342 suggestion.

Sometimes you have to browse your way through a lot of sub-directories. This command cd to the previous sub-directory in alphabetical order. For example, if you have the directories "lectures/01-intro", "lectures/02-basic", "lectures/03-advanced" and so on, and your PWD is "02-basic", it jumps to "01-intro".
