bashrc

• Extend the functionality of a bash shell by adding a few extra lines to the .bashrc:

  cdl() { clear -x ; cd "$1" ; pushd . > /dev/null ; tput setaf 1; pwd ; tput sgr 0 ; ls ; }

  cdp() { clear -x ; cd .. "$1" ; dirs -c ;tput setaf 1; pwd ; ls ;}

  Function cdl and cdp are extending the cd and cd .., respectively, with: (1) clearing the screen, (2) listing the content of the folder and (3) printing the current working directory as the first line.

  The cdl is extended with pushd as well, just in case you accidentally hit 'enter' after cd. When that happens type popd and you are back where you were instead of the '/home' directory.

  Example:

  • 

• Default auto completion in bash uses the tabulator key to match up until the next ambiguous character. In case you want to circulate between all possibilities (similaly to zsh default) use bind. Adding the following bind commands to the .bashrc will asign the key combination of LEFT-SHIFT + the UP arrow to bind and will execute the autocomplete by iteration through all complete possibilities, not just up untill the next common character.

  bind '"\e[1;2A":menu-complete-backward

  bind '"\e[1;2B":menu-complete'

  To list out all available sockets to bind see bind -ls. The LEFT-SHIFT+Up arrow has the ^[[1;2A metacharacter, while the LEFT-SHIFT+Down arrow has the ^[[1;2B.

• To further customize the shell use different colors for various extensions. Evaluate the .dircolors by: eval "$(dircolors -b .dircolors)"
