pushd, popd & dirs命令¶

start up with the following directories:

$ pwd
~/somedir
$ ls
dir1  dir2  dir3

pushd to dir1:

$ pushd dir1
~/somedir/dir1 ~/somedir
$ dirs
~/somedir/dir1 ~/somedir

pushd to ../dir3 (because we’re inside dir1 now):

$ pushd ../dir3
~/somedir/dir3 ~/somedir/dir1 ~/somedir
$ dirs
~/somedir/dir3 ~/somedir/dir1 ~/somedir
$ pwd
~/somedir/dir3

manually change directories to ../dir2:

$ cd ../dir2
$ pwd
~/somedir/dir2
$ dirs
~/somedir/dir2 ~/somedir/dir1 ~/somedir

Now start popping directories:

$ popd
~/somedir/dir1 ~/somedir
$ pwd
~/somedir/dir1

Pop again…:

$ popd
~/somedir
$ pwd
~/somedir
