List all commands present on system

a function to create a box of '=' characters around a given string.
First argument: string to put a box around. Second argument: character to use for box (default is '=') Same as command #4948, but shorter, and without the utility function.

a function to find the fastest free DNS server
Evoke from the command like as: $ timeDNS commandlinefu.com . This isn't too terribly practical, but it is a good code example of using subshells to run the queries in parallel and the use of an "anonymous function" (a/k/a "inline group") to group i/o. . I'm assuming you have already defined your local DNS cache as ${local_DNS}, (here, it's 192.168.0.1). . You do need to install `moreutils` to get `sponge`. . If you're willing to wait, a slower version w/o sponge, (and w/o sorting), is this: . DNS () { for x in "192.168.0.1" "208.67.222.222" "208.67.220.220" "198.153.192.1" "198.153.194.1" "156.154.70.1" "156.154.71.1" "8.8.8.8" "8.8.4.4"; do (echo -n "$x "; dig @"$x" "$*"|grep Query) ; done ; }

quickly backup or copy a file with bash
This inserts timestamp instead of .bak extension.

Find all files under a certain directory /home that have a certain suffix at the end of the file name. Show the file and rename them to remove the suffix.

Sort files in folders alphabetically
Creates one letter folders in the current directory and moves files with corresponding initial in the folder.

dd with progress bar and statistics
Will automatically take the size of the file but longer, usefull only if in an function.

Kill multiple instances of a running process

Bash alias for creating screen session containing IRSSI, named irssi, while checking if existing session is created
Bash alias for easy irssi within screen, attempts to attach to existing irssi session, if one exists, otherwise creates one - Including wipe for when system reboots and leaves "dead" session.
