lexec

Purpose

Locate executables

Syntax

Unix

Syntax: lexec [--verbose] pattern ...

Note that the pattern is a Python-style regular expression, not bash:

• The regular expressions are not anchored unless you use the ^ or $ metacharacters
• The asterisk metacharacter repeats the expression that precedes the asterisk
• etc.

Windoze only

Syntax: lexec [--verbose] [-s] pattern ...

See the note for a definition of system directories and explanation. | Do not search in system directories | | -v | Enable verbose debugging | Debugging is not enabled |

Example

Here’s an example that uses my flow tool on Linux:

[mrbruno@bruno-meerkat ~]$ lexec git | flow
/usr/bin/git-shell                 /usr/bin/sgitopnm                  /usr/bin/git-receive-pack          /usr/bin/git
/usr/bin/git-upload-archive        /usr/bin/git-upload-pack           /home/mrbruno/bin/git-log          /home/mrbruno/bin/gitpush.sh
/home/mrbruno/bin/gitstatus.py     /home/mrbruno/bin/old-git          /home/mrbruno/bin/gitrepos         /home/mrbruno/bin/gitstatus

[mrbruno@bruno-meerkat ~]$

Yes, I have a lot of files with “git” in the name and not all of them are even in this repo. I might not even use some of them anymore. I’m a packrat!

Notes

• The tool looks for executable files in directories that make up the shell’s $PATH environment variable
• No, Windoze is not a misspelling. It is the way I spell the operating system and if you don’t like it, tough.
• Windoze system directories are:
  • /c/Windows
  • /c/Program Files

  I found when using the tool on Cygwin and not ignoring these directories took an extraordinary amount of time and I was rarely interested in those files anyway. So by default they are ignored.
