Sometimes you have to browse your way through a lot of sub-directories. This command cd to the next sub-directory in alphabetical order. For example, if you have the directories "lectures/01-intro", "lectures/02-basic", "lectures/03-advanced" and so on, and your PWD is "02-basic", it jumps to "03-advanced".

This is meant for the bash shell. Put this function in your .profile and you'll be able to use tab-completion for sshing any host which is in your known_hosts file. This assumes that your known_hosts file is located at ~/.ssh/known_hosts. The "complete" command should go on a separate line as such:

function autoCompleteHostname() {

local hosts=($(awk '{print $1}' ~/.ssh/known_hosts | cut -d, -f1));

local cur=${COMP_WORDS[COMP_CWORD]};

COMPREPLY=($(compgen -W '${hosts[@]}' -- $cur ))

}

complete -F autoCompleteHostname ssh

This is useful for displaying a portion of a FILE that contains an error at line NUMBER
