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.
