Pgm for finding too long path/filenames.

I am wanting a program or utility or method of checking a large hierarchy of
folders and files and flagging somehow any that exceed the 255 character
path/filename
limit.
Hoping someone can help
TIA

find /path | awk 'length($0)>255{print $0}'

If you're such a smartarse, you'd check his headers:
Microsoft Outlook Express 6.00.2900.2670

and see your little linux command would do jack.

.... or in Windows-speak:

dir c:\/s/b | gawk "length($0)>255{print $0}"

Get gawk here:
http://unxutils.sourceforge.net/

(I note that gawk sometimes doesn't pipe ('|') well on Windows 2000,
so you may have to use this instead:

dir c:/s/b > dir.out
gawk "length($0)>255{print $0}" dir.out

Here's a C++ cmd line prog I've hastily modified to do it. It builds a
list then dumps it to the screen. It could write the list to a file if
you prefer. Send me an email if you want the .exe or some slight
changes. It doesn't recurse further when it hits a directory that
already exceeds max length. Builds with GCC. It has some stuff in it
you don't need that I've partly commented out. It might need a
plus/minus one correction somewhere for the length check - or maybe not.

Hi Brian,
This bash script should do the trick:

=========================
#!/bin/sh

MAX_LEN=255

ls -1R | while read f ; do
length=`expr length "$f"`
if [ $length -gt $MAX_LEN ]; then
echo "$f = $length"
fi
done
=========================

set MAX_LEN to the maximum length you want file names to be, includind their
directory path from the current directory.

Hope this helps,
Allistar.

If you're such a smartarse then you'd know that gawk is available for
Windows.

If you're such a smartarse then you'd know that Windows filesystems can
be viewed on Linux via Samba.

If you're such a smartarse then you'd know you can boot up Linux and
read Windows filesystems directly.

If you're such a smartarse you'd understand that whatever mail client
somebody uses doesn't mean much. I use OE quite often. But I also
run X with Windows as window manager.

You are so thick! Read Mark C's post.

I suggest you use a tool that shall help you with this problem especially when you tried different techniques yet still having the same problem all over again. Look for "Long Path Tool", then eventually you'll be able to manage you're folders well. Goodluck, Thanks
