Replace all tabs with spaces in an application

Note that this assumes the application is an SVN checkout and so we have to throw away all the .svn files before making the substitution.

Random numbers with Ruby

There's been a few times I've needed to create random numbers. Although I've done so in PERL, I've found Ruby is actually faster. This script generates 20 random "10" digit number NOT A RANDOM NUMBER. Replace 20 (1..20) with the amount of random numbers you need generated

change ownership en masse of files owned by a specific user, including files and directories with spaces

In the example, uid 0 is root. foo:foo are the user:group you want to make owner and group. '.' is the "current directory and below." -print0 and -0 indicate that filenames and directories "are terminated by a null character instead of by whitespace."

Compress archive(s) or directory(ies) and split the output file

a - archive

m5 - compression level, 0= lowest compression...1...2...3...4...5= max compression

-v5M split the output file in 5 megabytes archives, change to 700 for a CD, or 4200 for a DVD

R recursive for directories, do not use it for files

It's better to have the output of a compression already split than use the 'split' command after compression, would consume the double amount of disk space. Found at http://www.ubuntu-unleashed.com/2008/05/howto-create-split-rar-files-in-ubuntu.html

Organize a TV-Series season

It happened to me that I got a season of a tv-show which had all files under the same folder like /home/blah/tv_show/season1/file{1,2,3,4,5,...}.avi

But I like to have them like this:

/home/blah/tv_show/season1/e{1,2,3,4,5,...}/file{1,2,3,4,5,...}.avi

So I can have both the srt and the avi on one folder without cluttering much. This command organizes everything assuming that the filename contains Exx where xx is the number of the episode.

You may need to set:

IFS=$'\n'

if your filenames have spaces.
