18. If fime permits (or if you are waiting for otler students to finish this practice), use and understand pushd and popd. Use the man page of bash to find information about these commands.

man bash * opens the manual /puehd * searehes for pushd n # next (do t,hi.s trro/t.hree times)

The Bash shell has two built-in commands called pushd and popd. Both commands work with a common stack ofprevious directories. Pushd adds a directory to the stack and changes to a new current directory, popd removes a directory from the stack and sets the current directory. paulodebianl : / et cS cd,/bia paul@debian7: /bi-ng purbd ,/l.J.b /Llb /biyr paul@debian7 : /1ibg l,ucbd /proc /proc /ltb lbtrr paul@debian? : /procg popd /Lib /bLn pauledebi.an? : /libg popd /bLn
