Tree view in UNIX

I found this is interesting. If you like to get your directory structure in a tree view with a single command try following.

1. Create a shell script in directory /usr/local/bin/ (You need root permission)
   
2. Give it a name (I call it gr. )
   
3. Edit the script (usr/local/bin/gr)to include following command using a suitable editor (such as vi ;-))
   

   
   #!/bin/bash
   ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'
   

   
   
4. Give excutable rights
   

   % chmod +x /usr/local/bin/gr
   

   
   
5. Now go to any directory, (My preferred is Apache Rampart/C source) and issue
   

   % gr
   

   
   That should give you a tree view as follows.
   

      .
     |-core
     |-data
     |-handlers
     |-omxmlsec
     |---c14n
     |---openssl
     |---saml
     |---tokens
     |-secconv
     |-trust
     |-util
