Say I do the following:

cd /some/path
ln -s /target/path symbolic_name

If then do:

cd /some/path
cd symbolic_name
pwd

I get:

/some/path/symblic_name

and not:

/target/path

Is there a way to have the shell "fully resolve" a symbolic link (i.e. updating CWD, etc.), as if I had directly done:

cd /target/path

?

I need to run some programs that seem to be "aware" or "sensitive" about how I get to my target path, and I would like them to think that I arrived to the target path as if had done cd /target/path directly.

    Related to this question. You can do pwd -P or alias pwd='pwd -P' also cd -P to go to the physical path instead of the symlink. – Martín Canaval Feb 3 '13 at 22:25

Your shell has a builtin pwd, which tries to be "smart". After you did a cd to a symlink the internal pwd fakes the output as if you moved to a real directory.

Pass the -P option to pwd, i.e. run pwd -P. The -P option (for “physical”) tells pwd not to do any symbolic link tracking and display the “real” path to the directory.

Alternatively, there should also be a real binary pwd, which does not do (and is even not able to do) this kind of magic. Just use that binary explicity:

$ type -a pwd
pwd is a shell builtin
pwd is /bin/pwd
$ mkdir a
$ ln -s a b
$ cd b
$ pwd
/home/michas/b
$ /bin/pwd
/home/michas/a

Try cd -P <symlink_dirname>.

tim@ls:~$ mkdir a
tim@ls:~$ ln -s a b

tim@ls:~$ cd b
tim@ls:~/b$ pwd
/home/tim/b

tim@ls:~/b$ cd ..
tim@ls:~$ cd -P b
tim@ls:~/a$ pwd
/home/tim/a

You can also use set -o physical to make this behavior persist through the lifetime of the running shell.
