splits a postscript file into multiple postscript files. for each page of the input file one output file will be generated. The files will be numbered for example 1_orig.ps 2_orig.ps ...

The psselect commad is part of the psutils package

Convert all jpegs in the current directory into ~1024*768 pixels and ~ 150 KBytes jpegs

Renames files in a directory to incremental numbers, following alphabetic order. The command does not maintain extensions.

This heavy one liner gets all the files in the "/music/dir/" directory and filters for non 44.1 mp3 files. After doing this it passes the names to sox in-order to re-sample those files. The original files are left just in case.

This command will download $file via server. I've used this when FTP was broken at the office and I needed to download some software packages.

This takes quite a while on my system. You may want to test it out with /bin first, or background it and keep working.

If you want to get rid of the "No manual entry for [whatever]" and just have the [whatever], use the following sed command after this one finishes.

A shortcut to generate documentation with phpdoc. Defaults to HTML; optionally to PDF if third argument is given. Stores documentation in cwd under ./docs/. I forget the syntax to the output, -o, option, so this is easier.

count the times a domain appears on a file which lines are URLs in the form http://domain/resource.

-r to use extended regex

^ begin line

| alternative

get 100 or 0-9 one or two times

This will search all directories and ignore the CVS ones. Then it will search all files in the resulting directories and act on them.

Grab a list of MP3s (with full path) out of Firefox's cache

Ever gone to a site that has an MP3 embedded into a pesky flash player, but no download link? Well, this one-liner will yank the *full path* of those tunes straight out of FF's cache in a clean list.

Shorter and Intuitive version of the command submitted by (TuxOtaku)

Ever gone to a site that has an MP3 embedded into a pesky flash player, but no download link? Well, this one-liner will yank the names of those tunes straight out of FF's cache in a nice, easy to read list. What you do with them after that is *ahem* no concern of mine. ;)

Finds all (not just adjacent) repeated lines in a file.

make sure that flac and lame are installed

sudo apt-get install lame flac

file displays a files type

the -L flag means follow sym-links (as libraries are often sym-linked to another this behavior is likely preferred)

more complex behavior (*two* grep commands!) could be used to determine if the file is or is not a shared library.

lists the files found by find, waits for user input then uses xdg-open to open the selected file with the appropriate program.

usage: findopen path expression [command]

With the third optional input you can specify a command to use other than xdg-open, for example you could echo the filename to stdout then pipe it to another command.

To get it to work for files with spaces it gets a bit messier...

You can replace the @ with any character that probably wont be in a file name.

This is a dirty raw way to simply list ELF objects in a folder.

The output is ready to be parsed i.e to the stripper or what else needs a path to an ELF object.

You set the file/dirname transfer variable, in the end point you set the path destination, this command uses pipe view to show progress, compress the file outut and takes account to change the ssh cipher. Support dirnames with spaces.
