Determining directory path
Hello,

I have a script where I get the full directory path of the script being executed:

BASE=$0
echo "BASE:" $BASE

The output looks like this:
BASE: /webapps/appsdev/ACURA/rlz/oses3.sh

I'd like to truncate the shell name, leaving just the directory path. The directory path can be any number of levels deep. I think I need to truncate everything right of the last slash in the string.

Any ideas? I'm new at this.

-Thanks

GIT-MERGETOOL--LIB(1)						    Git Manual						     GIT-MERGETOOL--LIB(1)

NAME

       git-mergetool--lib - Common git merge tool shell scriptlets

SYNOPSIS

       TOOL_MODE=(diff|merge) . "$(git --exec-path)/git-mergetool--lib"

DESCRIPTION

       This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish
       scripts and/or are writing new ones.

       The git-mergetool--lib scriptlet is designed to be sourced (using .) by other shell scripts to set up functions for working with git merge
       tools.

       Before sourcing git-mergetool--lib, your script must set TOOL_MODE to define the operation mode for the functions listed below. diff and
       merge are valid values.

FUNCTIONS

       get_merge_tool
	   returns a merge tool.

       get_merge_tool_cmd
	   returns the custom command for a merge tool.

       get_merge_tool_path
	   returns the custom path for a merge tool.

       run_merge_tool
	   launches a merge tool given the tool name and a true/false flag to indicate whether a merge base is present.  $MERGED, $LOCAL, $REMOTE,
	   and $BASE must be defined for use by the merge tool.
