14.7 Nice Aliases for pushd

The pushd command ( 14.6 ) is nice for jumping around the filesystem. But some of the commands you might type a lot, like pushd +4 , are sort of a pain to type. I saw these aliases ( 10.2 ) in Daniel Gilly's setup file. They looked so handy that I decided to steal them for this book. There are C shell versions in the first column and bash in the second:

alias pd pushd                 alias pd=pushd
alias pd2 'pushd +2'           alias pd2='pushd +2'
alias pd3 'pushd +3'           alias pd3='pushd +3'
alias pd4 'pushd +4'           alias pd4='pushd +4'

So, for example, to swap the fourth directory on the stack, just type pd4 .
