Update - now fixed.

There's probably a more efficient way to do this rather than the relatively long perl program, but perl is my hammer, so text processing looks like a nail.

This is of course a lot to type all at once. You can make it better by putting this somewhere:

Then, to look up any command, you can do this:

This is similar to http://www.colivre.coop.br/Aurium/CLFUSearch except that it's just one line, so more in the spirit of CLF, in my opinion.

this command searches for a keyword or an expression in a path and avoids versionned files

By putting the "-not \( -name .svn -prune \)" in the very front of the "find" command, you eliminate the .svn directories in your find command itself. No need to grep them out.

You can even create an alias for this command:

Now you can do things like

What happens if there is more than a single space between words, or spaces and tabs? This command will remove duplicate spaces and tabs.

The "-r" switch allows for extended regular expressions. No additional piping necessary.

shortest alternative without the speed-o-meter"xclip large.xml"

"xclip -o" to get the clipboard content, alternatively [shift key] + insert or middle button of your mouse.

OK, not the most useful but a good way to impress friends. Requires the "display" command from ImageMagick.

avoid mouse abuse and the constant struggle of balancing scroll velocity ... not to mention that burning sensation in your upper right shoulder ....

this is useful to highlight only some code without losing other lines (eg. software, logs, scripts)

In turn you can get the contents of your clipboard by typing xsel by itself with no arguments:

This command requires you to install the xsel utility which is free

Built-in function in linux, should work on any distro

Bulit-in function in linux, so should work on any linux distribution.

You could start this one with

BUT using the find with "-type f" ensures you only get files not any dirs you might have

It'll also create backups of the files it's overwriting

Of course, this assumes that you don't have any files with duplicated filenames in your target structure

Inspired by http://www.commandlinefu.com/commands/view/2573/remove-all-files-previously-extracted-from-a-tar.gz-file. .... yet for zip files

Generates a frequency sweep from $x to $y, with $d numbers inbetween each step, and with each tone lasting $l milliseconds.

Found in comments section works on most Linux flavors.

Shows a list of running virtual machines on a vmware host (workstation/server/esx/etc.)

Again, this command is vmware-specific.

There are also other things you can do with `vmrun`. Just simply type vmrun by itself (no arguments) to get a readout of other things you can do with it.

There is no output from this command. The command boots a virtual machine and you will have to wait for the boot sequence to complete before you can ping or connect to the virtual machine via ssh/rdp/vnc/nx/etc.

To check if the table-of-content in a LaTeX document is up-to-date, copy it to a backup before running LaTeX and compare the new .toc to the backup. If they are identical, it is updated. If not, you need to run LaTeX again.

LaTeX is not a smart compiler - You need to run it several times to make it back-patch all the missing refs. The message if to do so or not is buried in its endless output and the log file. This grep lines helps to find it.
