Check These Out
Works on asterisk 1.8.
When using reverse-i-search you have to type some part of the command that you want to retrieve. However, if the command is very complex it might be difficult to recall the parts that will uniquely identify this command. Using the above trick it's possible to label your commands and access them easily by pressing ^R and typing the label (should be short and descriptive).
UPDATE:
One might suggest using aliases. But in that case it would be difficult to change some parts of the command (such as options, file/directory names, etc).
Only shows files with actual changes to text (excluding whitespace). Useful if you've messed up permissions or transferred in files from windows or something like that, so that you can get a list of changed files, and clean up the rest.
In this example, file contains five columns where first column is text. Variance is calculated for columns 2 - 5 by using perl module Statistics::Descriptive. There are many more statistical functions available in the module.
you can also run "xmms2 pause & at now +5min
Searches for dates on lines by themselves. Uses that date to prepend all rows that contain SEARCHSTRING with the date, until it reaches another line with a date by itself. This fixed an issue with a specific log export where there would be a date, followed by all of the entries for that date.
Branch name may be substituted, of course.
Do you have an entire album in a unique file and want to split it in individual tracks? If you also have the cue file you can do it!
Packages for Debian-based systems users:
* cuetools shntool
* FLAC (.flac): flac
* WavPack (.wv): wavpack
* Monkey's Audio (.ape): libmac2 monkeys-audio (deb http://www.debian-multimedia.org sid main)
NOTE: "sid" packages are unstable, but I didn't have problems with them. If you prefer, use the "stable" version repository.
To transfer the tags, you can use this (works with .flac, .ogg and .mp3):
$ cuetag sample.cue split-track*.flac
List the files a process is using.
You can return to defaults with "setxkbmap". More here: http://dailycli.blogspot.com/2009/12/xmodmap-replace-caps-lock-with-left.html
