'cd' option to change to the previous directory

I remember there was a way to execute the cd command, automatically returning to the previous directory (without an explicit cd ...). Is it possibl开发者_如何学Pythone?

If you just want to go back to the last directory, you can use cd -.

If you need more places to go back to, try pushd <dir> (instead of cd <dir>) and then you can go back with popd.

Found! I can execute it as a sub-shell.

A command list embedded between parentheses runs as a subshell.

Also, pushd and popd can come in very handy - they represent operations on a stack of directory locations - allowing you to "travel back in time".

You can also try the cdargs package. There is a tutorial.

Summary:

yum -y install compat-libstdc++-296
wget http://www.skamphausen.de/downloads/cdargs/cdargs-1.31-1.i386.rpm
rpm -ivh cdargs-1.31-1.i386.rpm
updatedb
source `locate cdargs-bash.sh`
# You can use any method you like for locating this file and running it
# Also, you need to put it in the ~/.bash_profile file to run it every time you log in
echo source `locate cdargs-bash.sh` >> ~/.bash_profile
cdb

Mark a directory and move around:

cd /etc/conf/httpd/ext/
mark apaconf
cd /usr/local/src/
cdb apaconf
