"non recursive find" or "how to get the age of a file"

Alexandre W. Agostini — Tue, 01 Jul 2003 19:34:00 GMT

Hi people!

Does anyone knows how to convince a find command not to descend the filesystem hierarchy and search only the current directory?

The reason for that are: I need to remove a certain file just if it's more than 7 days old. The problem is that it sits on top of a very large directory structure and I can't afford to wait the find traverse the whole place before finally look around and see the file. :)

Thanks already!

cd to that directory then

find . -name "yourfile"

or

find /yourdir -name "your file"

-USA..

find . -maxdepth 0
will operate only on the current directory.

Try-

find . -path "./*" -prune -mtime +7 -print

The "-path" can limit the file path and "-prune" will prevent find from descending subfolders.

If you wanted to do one level down of directories-

find . -path "./*/*" -prune -mtime +7 -print

That was my first attempt, but when the directory where I am have several others sub-directories each one having a lot of files the find will search those sub-directories also and the search takes much more time. How could I tell find to skip all sub-directories and search just the current one?

That's what "prune" does. It prunes the branches of the tree.

Bingo!

That's perfect!

I was really messing up with the -prune syntax.

Thanks!

Regarding "...remove a certain file just if it's more than 7 days old..."

I believe find uses a zero based counter where 0 = 24 hours. So for seven days use 6.

-ctime +6

GNU find is superior and uses 'maxdepth'.

find /dir/sub_dir -maxdepth 0 -ctime +6 -exec rm {} \;

-atime - read or view but don't write to. (* access *)
-mtime - write to. (* modify *)
-command line level only

So toy around with atime and ctime.

Here's GNU find:

by combining ls & find you can run:
#!/bin/ksh
for i in `ls *fname*`
do
if [ -f $i ]
then
find $i -atime +7
fi
done
