List PHP-FPM pools by total CPU usage

Show all configured ipv4
Short list of all ip. Shows even the newly supported multiple ip address on the same interface (see eth1). For ipv6 use -6

Start another instance of X via SSH

find and delete empty dirs, start in current working dir

move a lot of files over ssh
Useful to move many files (thousands or millions files) over ssh. Faster than scp because this way you save a lot of tcp connection establishments (syn/ack packets). If using a fast lan (I have just tested gigabyte ethernet) it is faster to not compress the data so the command would be: tar -cf - /home/user/test | ssh user@sshServer 'cd /tmp; tar xf -'

Rename files in batch

convert mp3 into mb4 (audiobook format)
to convert a whole directory, put all mp3 files in a for loop $ for i in $(ls *mp3); do mpg123 -s $i | faac -b 80 -P -X -w -o ${i%mp3}m4b -; done

Update zone file Serial numbers
Will edit *.db files in the same directory with todays date. Useful for doing a mass update to domains on a nameserver, adding spf records, etc. Looks for a string starting with 200 or 201 followed by 7 numbers, and replaces with todays date. This won't overwrite Ip's but i would still do some double checking after running this. Make sure your server's date is correct, otherwise insert your own serial number. $rndc reload should usually follow this command.

See entire packet payload using tcpdump.
This command will show you the entire payload of a packet. The final "s" increases the snaplength, grabbing the whole packet.

Watch active calls on an Asterisk PBX
Works on asterisk 1.8.
