  • Tested with bash v4.1.5 on ubuntu 10.10 Limitations: as written above, only works for programs with no file extention (i.e 'proggy', but not 'proggy.sh') because \eb maps to readine function backward-word rather then shell-backward-word (which is unbinded by default on ubuntu), and correspondingly for \ef. if you're willing to have Ctrl-f and Ctrl-g taken up too , you can insert the following lines into ~/.inputrc, in which case invoking Ctrl-e will do the right thing both for "proggy" and "proggy.sh". -- cut here -- \C-f:shell-backward-word \C-g:shell-forward-word "\C-e":"\C-f`which \C-g`\e\C-e" -- cut here -- Show Sample Output

    bind '"\C-e":"\eb `which \ef`\e\C-e"'

Save the list of all available commands in your box to a file
When you press TAB twice in your prompt, bash tells you something like "Display all 4567 possibilities? (y or n)" But when you press "y" you only get the list in the terminal output and, if you want to save it to a file, you have to copy it by hand from the vterm screen. With this utility you save the list to a file or pipe it to another command at will You can use the file saved list to grep for a particular pattern, useful if you are searching for a command but you only remember a few letters

Find out how much data is waiting to be written to disk
Ever ask yourself "How much data would be lost if I pressed the reset button?" Scary, isn't it?

Convert Youtube videos to MP3
youtube-dl has this functionality built in. If you're running an older version of youtube-dl, you can update it using `youtube-dl -U` (although if you have an older version, it probably doesn't download youtube videos anyway.) youtube-dl --help will show you other options that may come in useful.

Use a var with more text only if it exists
See "Parameter Expansion" in the bash manpage. They refer to this as "Use Alternate Value", but we're including the var in the at alternative.
