Solaris, HPUX11.11:
find . -type f -mtime +45 -exec tar cf ../file.tar {} +
If none of the above works, and file names do not have spaces:
find . -type f -mtime +45 -print | xargs tar cf ../file.tar

The foolproof way requires first creating a tarfile ("c" option) with a single
file , then using one of the above find commands, with the 'u' option,
_instead_ of 'c'. if that single file is small, nothing is really hurt
if it also gets included in the stuff done by the 'find' command.
Some versions of tar * and moan if you specify 'u' or 'r', and the
tarfile _does_not_ exist.

But as Jim points out elsethread, the find -exec and xargs versions are
dangerous and should not be used.
Probably the best portable answer is to use a two-step process:
first, use find to create either an include or an exclude list, then,
second, call tar with the include or exclude list. Alternatively, use
cpio (which does read stdin) rather than tar.

If you really do want the creation date, and the files
may have been modified since creation, then you need
to store the creation date yourself, perhaps by including
it in the filename (eg file.2005-08-13).

1. "find"ing directories older than 7 days old.
Hi,
Find is creating me yet more puzzles.
What I am trying to do is, remove all directories that are older than
7 days. I have set up a daily cron job and the script looks something
like this.
ARCHDIR=/home/nigel/archive
for i in 'find ?????what should I pt here???????'
do
rm -r $i
done
Every night a new directory is created and some files are backup up
there, every day someone has to find last weeks archive directorys sub
directory of that day last week and delete it.
This can be automated can't it?
Cheers,
