Added -P to CD handle symbolic links in PWD
The use of plain "cd" with a symbolic link to a directory maintains the
logical name (i.e., includes the link's name), hence in a script, when a path
is set using "pwd", that path includes the link instead of the full physical
path. This is a problem when the path is used (e.g in "cd .." -- which ends in
the wrong place !!)
Adding the "-P" option makes "cd" follow the physical name. For example:
[mapr@mfs91 ~]$ ls -l ~/drill/bin
lrwxrwxrwx 1 mapr mapr 79 Oct 18 16:55 /home/mapr/drill/bin ->
distribution/target/apache-drill-1.9.0-SNAPSHOT/apache-drill-1.9.0-SNAPSHOT/bin
[mapr@mfs91 ~]$ cd ~/drill/bin ; pwd
/home/mapr/drill/bin
[mapr@mfs91 bin]$ cd -P ~/drill/bin ; pwd
/home/mapr/drill/distribution/target/apache-drill-1.9.0-SNAPSHOT/apache-drill-1.9.0-SNAPSHOT/bin
