This bash alias will take a directory name or path as an argument.
alias goto='cd $1' |
This is an example of how this alias works.
jason@jason-desktop:~$ 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.
