find all email addresses in a file, printing each match. Addresses do not have to be alone on a line etc. For example you can grab them from HTML-formatted emails or CSV files, etc. Use a combination of
...|sort|uniq$
to filter them.

Search for the string "search" and replace it with the string "replace", on all files with the extension php in the curret folder. Do also a backup of each file with the extension "bkp".
Good for summing the numbers embedded in text - a food journal entry for example with calories listed per food where you want the total calories. Use this to monitor and keep a total on anything that ouputs numbers. Show Sample Output
This command will open up the two files in FileMerge on OS X. You can also compare two directories.
opendiff directory1 directory2
NOTE: FileMerge is a part of the OS X Developer Tools, available on the install disc.
Tells sort to ignore all characters before the Xth position in the first field per line. If you have a list of items one per line and want to ignore the first two characters for sorting purposes, you would type "sort -k1.3". Change the "1" to change the field being sorted. The decimal value is the offset in the specified field to sort by.
If you're users have ever asked your script to email their reports in separate attachments instead of tar'ring them into one file, then you can use this. You'll need the mailx package of course. In Unix you'd want to add an additional parameter "-m" (uuencode foo.txt foo.txt; uuencode /etc/passwd passwd.txt)|mailx -m -s "Hooosa!" someone@cmdfu.com
Uses process signal to play next selection
Pressing ESC then * will insert in the command line the results of the autocompletion.
It's hard to explain but if you look the sample output or do
echo ESC *
you will understand quickly.
By the way, few reminders about ESC :
- Hold ESC does the same thing as tab tab
- 'ESC .' inserts the last argument of last command (can be done many times in order to get the last argument of all previous commands)

curl doesn't provide url-encoding for 'GET' data, it have an option '--data-urlencode', but its only for 'POST' data. Thats why I need to write down this commandline. With 'perl', 'php' and 'python', this is one liner, but just I wrote it for fun. Works in Ubuntu, will work in all linux varients(I hope it will work in unix varients also). Show Sample Output
This will extract all of the urls from a firefox session (including urls in a tab's history). The sessionstore.js file is in ~/.mozilla/firefox/{firefox profile}

Simple way to achieve a colored SVN diff
Obviously, you can replace 'man' command with any command in this command line to do useful things. I just want to mention that there is a way to list all the commands which you can execute directly without giving fullpath. Normally all important commands will be placed in your PATH directories. This commandline uses that variable to get commands. Works in Ubuntu, will work in all 'manpage' configured *nix systems. Show Sample Output
You can convert any UNIX man page to .txt
It's also possible to delay the extraction (echo "unrar e ... fi" |at now+20 minutes) wich is really convenient!
Yes, it's useless.
Chronic Bash function:
chronic 3600 time # Print the time in your shell every hour
chronic 60 updatedb > /dev/null # update slocate every minute
Note: use 'jobs' to list background tasks and fg/bg to take control of them.
You can flexibly change file pattern(*.tar.gz) and uncompress command to other job! Example, remove all files : for i in *.tar.gz; do rm $i; done (Just for example, because if you really want to remove file, simply use wildcard like this rm *.tar.gz)

Performs a mysqldump and gzip-compresses the output file with a timestamp in the resulting dump file. Inspect the file for integrity or fun with this command afterward, if you desire:
zcat mysqldump-2009-06-12-07.41.01.tgz | less

I've been auto-generating some complex GnuPlots; with multiplots the first plot of each group needs to be a 'plot' whereas the others need to be 'replots' to allow overplotting/autoscaling/etc to work properly. This is used to replace only the first instance of 'replot'. Show Sample Output
command | my_irc
Pipe whatever you want to this function, it will, if everything goes well, be redirected to a channel or a user on an IRC server.
Please note that :
- I am not responsible of flood excesses you might provoke.
- that function does not reply to PINGs from the server. That's the reason why I first write in a temporary file. Indeed, I don't want to wait for inputs while being connected to the server. However, according to the configuration of the server and the length of your file, you may timeout before finishing.
- Concerning the server, the variable content must be on the form "irc.server.org 6667" (or any other port). If you want to make some tests, you can also create a fake IRC server on "localhost 55555" by using
netcat -l -p 55555
- Concerning the target, you can choose a channel (beginning with a '#' like "#chan") or a user (like "user")
- The other variables have obvious names.

Nice reading in the morning on the way to work, but sadly the .tar.gz for the whole issue 66 is not on phrack's website yet. So use wget to download.
