In a bash shell script today I noticed the below command at the end of the script. I know what is cd but I am unaware of the significance of a dash after it.
cd -
What does this mean? Google naively truncates the - so I am unable to find its answer.
If a single dash is specified as the argument, it will be replaced by the value of
OLDPWD.The
OLDPWDis set bycdcommand and it is the previous working directory.
