This bash alias will take a directory name or path as an argument.
alias goto='cd $1'
This is an example of how this alias works.
[email protected]:~$ goto /usr/share jason@jason-desktop:/usr/share$
This is a very neat bash trick. This might not work if the directory name uses spaces though.
Generate a very complex password with the Linux command line.
echo; head -5 /dev/urandom | tr -d -c '[:alnum:]' ; echo
Just read from /dev/urandom an filter out anything that is not a letter or number. This still creates a very secure password.
