I wanted to play a song from the shell and get the shell back, I also dont want to store the file if it is not needed.

edit, not sure if I need to mention it... killall vlc to stop it

compare to alternative :

- directly tests the -STOP of the process to continue or stop loop,

- background operator should be set (or not) at the call of the function

For extension i suggest a slowPID() based on kill like above and a slowCMD based on killall.

PLAYLIST=$(ls -1) ; mpg123 -C $PLAYLIST
2009-03-19 17:20:28
Functions: ls mpg123

On my music directory, I create variable that contains all mp3s files, then I play them with mpg123. -C options enable terminal control key, s for stop, p for pause, f for forward to next song.

User: dinomite
Functions: cut grep host

Get just the IP address for a given hostname. For best results, make this a function in your shell rc file so that it can be used for things like traceroute:

Titus:~$ traceroute `getip foo.com`

traceroute to (, 64 hops max, 52 byte packets

Have wc work on each file then add up the total with awk; get a 43% speed increase on RHEL over using "-exec cat|wc -l" and a 67% increase on my Ubuntu laptop (this is with 10MB of data in 767 files).

By default, slot 1 is used for OTP purposes and validates against the Yubikey servers. Running the command above will replace that. If you have a Yubikey 2 or above, you can change -1 to -2 and program the second slot with a strong static key.

Functions: awk cut sed

This is an easy way to quickly get a status for a device in multipath on SLES systems, as long as the server is configured based on Novell's standards, where multipathed disks are referred to by /dev/disk/by-... tree. Make sure to replace name_of_vg with your Volume Group name.

In MySQL client, \P less -S
2011-01-19 09:44:43
User: maxmanders
Functions: less

Instead of dumping the entire query to the screen, it will use 'less -S' to handle pagination. This means you can move back and forward through the result set, and instead of wrapping rows at screen boundaries, the table will extend off the screen, and can be scrolled left and right with arrow keys.

alias viaco='task="$(basename "$(pwd)")"; if [ -f "$task.c" ]; then vi -c "set mouse=n" -c "set autoread" -c "vsplit $task.out" -c "split $task.in" -c "wincmd l" -c "wincmd H" $task.c; fi'

1. Get name of task by task=$(basename "$(pwd)")

2. Check whether "$task.c" exists as a file

3. open "$task.c", "$task.in", "task.out" in vim with such layout.

Functions: echo fdisk

This is a bit hacky, but if you're setting up a bunch of new LUNs, it can save a bunch of time. Also check out sfdisk. The fdisk will fail if, for example, a partition table already exists.

dhclient wlan0 && sbnt=$(ifconfig wlan0 |grep "inet addr" |cut -d ":" -f 2 | cut -d "." -f 1-3) && nmap $sbnt.0/24 -sP

User: wltj
Functions: cut grep ifconfig

This is helpful if you connect to several networks with different subnets such as 192 networks, 10 networks, etc. Cuts first three octets of ip from ifconfig command and runs nmap ping scan on that subnet.

Replace wlan0 with your interface. Assumes class c network, if class b use: cut -d "." -f 1-2 and change nmap command accordingly.
