One Day One GNU/Linux Command
=============================
cd -- Change the Current Directory
Summary:
cd is bash shell's built-in command. It is used to change the present
working Dir to specific Dir.
Examples:
$ cd -- Change the current Dir to $HOME ($HOME is the default).
$ cd ~ -- Same as above.
$ cd ~bharathi -- Goto the Home Dir of bharathi.
$ cd myprj -- Change the current Dir to myprj.
$ cd .. -- Goto the parent Dir.
$ cd - -- Goto the last visited Dir.
TIP:
CDPATH - Easy access to frequently used Dirs. For example, I use
/usr/a/dir1, /usr/b/dir2/ and /usr/c/dir3 folders very frequently.
So I added the above dirs in CDPATH like this
$ export CDPATH=/usr/a/dir1/:/usr/b/dir2/:/usr/c/dir3/
Now there is no need for me to type exact path to cd. Just cd dir1
will cd to /usr/a/dir1. Actually cd will looks into CDPATH before
doing the action.
Note:
1) Before changing to new path, cd will save the old path in the
$OLDPWD evn variable.
2) After changing to new path, cd will save the new path in the $PWD
env variable.
