I got the terminiology all wrong but find on my system does not allow -L

Here what works:

    # '-follow' is supposed to be deprecated, but the replacement
    # '-L' specified in 'man' and 'info' pages does not appear to
    # exist in Cygwin 'find' version 4.5.4
    find "$PWD" -maxdepth 1 -type f -follow -executable | gawk '

If I replace '-follow' with '-L' it tells me :

find: unknown predicate `-L'

Nope. The line is from a larger script and I need rooted paths.

No, I want to find all files whether normal or links that are executable.

Thanks for your help, and sorry about my prior confusion.

The larger script, 'rwhich', finds all commands that match an extended
regular expression.

E.g.:

  $ rwhich '^e_[bm]?s$'
  /local/Scripts/e_bs
  /local/Scripts/e_ms
  /local/Scripts/e_s

It works, now, and I've needed this for a long time. Glad it finally works.


Now, if I can only figure out how not to be bitten by Comcast's
motherlovin' bandwidth throttleing while I'm updating Cygwin. Sigh!
