Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Replace "[email protected]" with the target e-mail address. Thanks to alediaz for "$HOSTNAME" which is very useful when running the command with Apple Remote Desktop to multiple machines simultaneously.

Shows all those processes; useful when building some massively forking script that could lead to zombies when you don't have your waitpid()'s done just right.

Run the function phpinfo() on the shell

echo "<?php phpinfo(); ?>" >> /srv/www/htdocs/test.php

Simple command to convert a large number of images into jpeg-format. Will delete originals after conversion.

OSX's BSD version of the du command uses the -d argument instead of --max-depth.

Use `zless` to read the content of your *rss.gz file:

jhead is a very nice tool to do all sorts of things with photographs, in a batch-oriented way. It has a specific function to rename files based on dates, and the format I used above was just an example.

ls -1 *.jpg | while read fn; do export pa=`exiv2 "$fn" | grep timestamp | awk '{ print $4 " " $5 ".jpg"}' | tr ":" "-"`; mv "$fn" "$pa"; done

Renames all the jpg files as their timestamps with ".jpg" extension.

In Bash, when defining an alias, one usually loses the completion related to the function used in that alias (that completion is usually defined in /etc/bash_completion using the complete builtin).

It's easy to reuse the work done for that completion in order to have smart completion for our alias.

That's what is done by this command line (that's only an example but it may be very easy to reuse).

Note 1 : You can use given command line in a loop "for old in apt-get apt-cache" if you want to define aliases like that for many commands.

Note 2 : You can put the output of the command directly in your .bashrc file (after the ". /etc/bash_completion") to always have the alias and its completion

for f in *.eps;do ps2pdf -dEPSCrop $f `basename $f .eps`.pdf; done

since fuse mounts do not appear in /etc/mtab (fuse can't write there, dunno if it would if it could) this is propably a better way.
