changing and restore working directory in bash

curr_dir=`pwd`
cd $dir

##  Do some processing
##
cd $curr_dir


Is this inefficient way of restoring directory in bash script or is there some other standard way?

The variable OLDPWD is filled automatically, so no need for "curr_dir=`pwd`"

cd $dir
##
##  Do some processing

cd $OLDPWD

"cd -" will do exactly the same as "cd $OLDPWD && pwd", i.e. it return to the previous working directory and if successful print out its name.

If your shell is "bash" please see also the "pushd", "popd" and "dirs" builtin commands (consult the manpage for "bashbuiltins").
