I have seen several pushd/popd for the shell, lately, but they don't
behave like the Cshell's. This one looks to the user like the 4.1 version
(it doesn't have the '+n' option).
----------
DSTACK=''
pushd(){
SAVE=`pwd`
DSTACK="$SAVE $DSTACK"
if [ "$1" = "" ] ; then
if [ "$DSTACK" = "$SAVE " ] ; then
echo "pushd: No other directory"
DSTACK=""
return 1
fi
set $DSTACK
cd $2
shift
shift
DSTACK="$SAVE $*"
else
if (cd $1) ; then
cd $1 >&-
else
popd > /dev/null
return 1
fi
fi
dirs
return 0
}
popd(){
if [ "$DSTACK" = "" ] ; then
echo "popd: Directory stack empty"
return 1
fi
set $DSTACK
cd $1
shift
DSTACK=$*
dirs
return 0
}
dirs(){
echo "`pwd` $DSTACK"
return 0
}
