I'm a complete newbie to bash scripting.
I remember there was a way to execute the cd
command, automatically returning to the previous directory (without an explicit cd ...
).
Any idea?
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. You can find a tutorial here: http://www.csrdu.org/nauman/2011/01/16/helpful-tips-for-newbie-system-admins/
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 to run it every time you login
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
See the link for other commands or search the net.
