KDE4 is great, but still a bit buggy, and sometimes plasma requires to be restarted. Instead of quitting it with "killall plasma", which might loose your preferences (widgets, etc.), kquitapp will cleanly quit it. Tip: you can type this in the "Alt+F2" window, and then type "plasma" in Alt+F2 again to restart plasma (be patient though...).

The sample command searches for PHP files replacing tabs with spaces.

Instead of

one may pass

for instance.

Here's the other way of doing it in vim: setting a recursive macro. 'gg' brings you to the top of the buffer, 'qqq' clears the 'q' macro, 'qq' starts recording a macro called 'q', '/^$' moves the cursor to the next empty line, 'dd' deletes the line that the cursor is on, '@q' calls the 'q' macro (currently empty because of 'qqq'), and 'q' stops recording the macro. '@q' calls the macro.

It will run until it cannot find another blank line, at which point it will throw up an error and cease.

While this is longer than the regex, you can use it without having to move your thoughts from 'vim-mode' to 'regex-mode'.

You can use this command to delete CVS/svn folders on given project.

#Sample Usage:

# git commit -m"Jira #404 - `whatthecommit`"

#

If you have a directory with many working copies of various subversion projects and you want to update them all at once, this one may be for you.

This awk command prints a histogram of the number of times 'emergency' is the first word in a line, per day, in an irssi (IRC client) log file.

You should install qpdf.

That way, you can have a copy without any password required.

cn stands for "Cat Null"

.

The idea is that sometimes you run across something on maybe a webpage - like commandlinefu - that you want to try out on your terminal. You could put a '#' in and then paste it, but what if it is several lines?

.

This command will echo the pasted characters to the screen and divert them to the bit bucket.

Put this simple alias in your .bashrc, hit cn, paste away, and hit a ctrl+c or a ctrl+d when you are done to get your prompt back.

This should work on any unix platform running bash. Just type the program into cat and give it a ^D when you're done, at which time it will compile, run, and remove the program. Obviously, you can run it without the "rm a.out" if you'd like to keep the binary. If you want to keep the source, well, you might as well just write it in vi or emacs first then.

Finds the line number matching the regex, then passes that to BC for some math, passes that to head, and uses tail to trim off the unwanted section at the top. The whole thing is spit out to a script that can then be shared or run. Comes in handy for reading select sections from error logs.

I often run some command that takes a while to finish. By putting the say command afterward, I get an audio notification.

Please note that this command (say) only works on Mac OS X and not Linux.

Compresses each file individually, creating a $fileneame.tar.gz and removes the uncompressed version, usefull if you have lots of files and don't want 1 huge archive containing them all. you could replace ls with ls *.pdf to just perform the action on pdfs for example.

In order to create a new encrypted filing system managed by cryptmount,

you can use the supplied 'cryptmount-setup' program, which can be used

by the superuser to interactively configure a basic setup.

Alternatively, suppose that we wish to setup a new encrypted filing

system, that will have a target-name of "opaque". If we have a free

disk partition available, say /dev/hdb63, then we can use this directly

to store the encrypted filing system. Alternatively, if we want to

store the encrypted filing system within an ordinary file, we need to

create space using a recipe such as:
