Just create a function in your .bashrc like this

shorturl() {

curl -s -d URL="$1" http://is.gd/create.php | sed '/Your new shortened/!d;s/.*value="\([^"]*\)".*/\1/'

}

Assuming that $script contains the filename of a script you'd like to post as part of a comment on this site, this will prefix each line with '$' and pipe it into the X selection. From there just put the cursor in the right place in the comments box and middle-click.

Should work pretty much anywhere with xclip installed. On debian-ish systems this is installed as part of the package "xclip".

search argument in PATH

accept grep expressions

without args, list all binaries found in PATH

With this simple sed command we can easily comment and entire file.

Connect to a machine running ssh using mac address by using the "arp" command

Checks the Gmail ATOM feed for your account, parses it and outputs a list of unread messages.

For some reason sed gets stuck on OS X, so here's a Perl version for the Mac:

If you want to see the name of the last person, who added a message to the conversation, change the greediness of the operators like this:

From there, just pkg install the package you need.

If you still connect to your wireless access point manually and need to use wpa_supplicant, the above fu will grep all of the known SSID from your wpa_supplicant.conf file, present it in a Zenity list and return the SSID name you choose. I've wrapped this command in to a bash script that then up's the interface, associates and autenticates. Saves me from using NetworkManager ;)

With this one liner you can easily output a standard help message using the following convention:

Usage: is the start marker

Stop at the last #

Manages everything through one sed script instead of pipes of greps and awks. Quoting of shell variables is generally easier within a sed script.

Based on the MrMerry one, just add some visuals to differentiate files and directories

Based on the MrMerry one, just add some visuals and sort directory and files

free swap

grab the weather, with a little expletive fun. replace the 48104 with a US zipcode, or the name of your city (such as ZIP="oslo"), unless you want to know what the weather is like for me (and that's fine too)

Copy the link to an HD movie trailer in to this command. It's more eleganant if it's put in a to a script, taking the URL as input.

another method :

awk '{gsub(/:/, "\n");print}'

"&&" runs sed if and only if the backup completed and /bin/cp exited cleanly. Works for multiple files; just specify multiple filenames (or glob). Use -v switch for cp to play it safe.
