Shell Programming and Scripting

I think it should be '-maxdepth 0' then it will work,

how ever man pages definetly say that -purne option will not allow find to search in subdirectories of current directory...

cheers,

maxdepth 0 has maximum of one line of output -- TITS. (Try It To See)

maxdepth -1 outputs the contents of one directories, without recursing into subdirs.

At least, seems that way to me

A use that I have found for the prune option is to find everything in a directory but skip version controlling dirs and their contents, eg folders named .csv or .svn.

find . -type d -name .svn -prune -false -o -type f

Most recent HP-UX find man page: HP-UX find(1)
Most recent Solaris find man page: Solaris find(1)
The official Posix standard for find: IEEE Std 1003.1, 2004 Edition find

Please notice what these documents have to say regarding the -maxdepth option: not one word. Solutions involving -maxdepth are not portable at all.

Well, I can find only two flavors of -maxdepth and neither supports the view that output is limited to a single line. When I tried it...

Code:

$ touch one two three
$ find one two three -maxdepth 0 -type f
one
two
three
$ find .
.
./one
./two
./three
$

Thanks for pointing that out.

I hadn't really thought about portability, but I am going to try be more "portably" correct.

In terms of portability, I am assuming that the posix definition should be fairly portable, so I will pay the most attention to that.

Try this :

#!/bin/sh

i="/pat/to/dir/you/wanna/check/"
msg () {
for i
do echo "clearing: $i" >&2
done
}

fatal () { msg "$@"; exit 1; }

if [ ! -d "$i" ]
then msg "no directory: $i"
elif [ ! -r "$i" -o ! -w "$i" ]
then msg "access denied (no rw- access): $i"
else
# search & destroy
find "$i" ! -type d -mtime +30d -print | xargs rm -f > /dev/null 2>&1

[ -d "$i" ] || continue
(cd $i || continue
for d in *
do
[ -d "$d" ] || continue
find . -depth -type d -mtime +30d -print |
xargs rmdir > /dev/null 2>&1
done
)
fi
exit 0

This works for me to delete files 30 days old from directory $i in depth
