I launch script.sh and inside it i want to know what is his name

Is there a standard procedure to know the scripts name ? the idea is to be able to extract the name from teh full path + name contained in $0

Thanks

    So are you just looking for basename? Commented May 10, 2010 at 18:07
  • Or are you asking about dereferencing symlinks (perhaps with readlink)? Commented May 10, 2010 at 18:07
  • there are many ways to extract the file name from the full path like using basename,cut,awk etc. Commented May 11, 2010 at 12:36
  • see also: stackoverflow.com/questions/192319/… and note that $0 will pull the parent name if you exec the script with source Commented Nov 16, 2016 at 19:12

Yes, $0 will always contain the name of the script. Use basename to extract the name.

basename /some/really/long/dir/path/myscripts/coolscript.sh will print coolscript.sh

So in your script, you could do this:

my_scriptname="$(basename $0)"

This my_scriptname=$(basename "$0") would be better.

script="${0##*/}"

Edit:

This does the same thing as basename $0. It strips off the last slash and everything before it from $0 using Bash's brace expansion.

basename $0 will give you the script name

basename doesn't strip extensions unless you ask it to.
