Tutorial :How can I find the location of the tcsh shell script I'm executing?


Say I put an executable tcsh file in /path/to/my_script.csh

and my current directory is anywhere, for example I'm in /path

So I type to/my_script.csh

I want to have a line in my_script.csh that will return "/path/to/my_script.csh" - like ruby's



If you want to ensure the same result (full path and script name) try something like this:

...  rootdir=`/bin/dirname $0`       # may be relative path  rootdir=`cd $rootdir && pwd`    # ensure absolute path  zero=$rootdir/`/bin/basename $0`  echo $zero  ...  

Then you can call it as foo.sh, ./foo.sh, some/lower/dir/foo.sh and still get the same result no matter how it is called.


In c shell, try like this:

set rootdir = `dirname $0`  set abs_rootdir = `cd $rootdir && pwd`  echo $abs_rootdir  


#!/bin/tcsh  echo "I am $0."  


If you want an absolute path then this should help you out:

#!/bin/tcsh -f   set called=($_)    if ( "$called" != "" ) then  ### called by source      echo "branch 1"     set script_fn=`readlink -f $called[2]`  else                         ### called by direct excution of the script     echo "branch 2"     set script_fn=`readlink -f $0`  endif    echo "A:$0"  echo "B:$called"  set script_dir=`dirname $script_fn`    echo "script file name=$script_fn"  echo "script dir=$script_dir"
