History.dat052903
History.dat053003

History.dat060203 ]

Delete Files
History.dat060903
..

My requirement is , on every monday i need to delete the input files those i received week before last week.
i.e in the above case , on 06/09/03 i need to delete files received from 05/26/03 thru 05/30/03.

Hope i'm making myself clear.

Thanks in Advance.

If I understand the question correctly, a find command should do the trick:

find /directory -type f -name History.dat* -mtime +5 -exec rm {} \;

You can do this with "mtime" option of find command:

# find /dir_name -name History.dat* -type f -xdev -mtime +7 -exec rm {} \;

This will delete all files which was not modified for the last 7 days. If you want to include last accessed option too, then add -atime with find command. If you want to print a list of files which were deleted, then inlcude -exec ll {} \; with find command.

Hi!!

Try the following:

find /dirname -name History.dat* -type f -mtime +5 -exec rm {} \;

You can add this line to a cleanup/housekeeping script or create a script that contains this line and add the script to the user's crontab.

$ find /home/dmeload/CMI -name History.dat* -type f -xdev -mtime +7 exec rm {} \;

when i give the above it gives me error saying,
"find: missing conjunction"

For the last question:

Put the file name - History.dat* in quotes:

# find ..options ..-name 'History.dat*' ..options

That will solve the issue.

you need to enclose the 'History.dat*' in single quotes so that the shell does not expand the '*'.

Re: Delete Files

Pete Randall — Mon, 02 Jun 2003 16:50:42 GMT

Sorry about that, Raj. I always forget the quotes until it errors on me. And I should have made the mtime 7 instead of 5. But you got the idea.

Hi:

Using an 'find' expression with a wildcard should be quoted to prevent the shell from expanding it:

# find /home/dmeload/CMI -name "History.dat*" -type f -xdev -mtime +7 exec rm {} \;

$ find /home/dmeload/CMI -name 'History.dat*' -type f -xdev -mtime +7 exec rm {} \;

$ find /home/dmeload/CMI -name "History.dat*" -type f -xdev -mtime +7 exec rm {} \;

Both throws same error.

Again, are you using exec or -exec ? From your posts, it looks like you are using exec with minus (-) sign.

Re: Delete Files

Prabhu_7 — Mon, 02 Jun 2003 17:02:37 GMT

FYI...

$ uname -a
HP-UX dmeserv B.11.00 U 9000/899 1459612391 unlimited-user license

Is anything to do with this ?

Re: Delete Files

Pete Randall — Mon, 02 Jun 2003 17:04:11 GMT

Raj,

You need a minus sign in front of "exec":

-exec rm {} \;

Pete

Re: Delete Files

Helen French — Mon, 02 Jun 2003 17:04:34 GMT

Oops.! Correction on my last post. "It look like you are using exec WITHOUT minus (-) sign." You should use - sign woth exec option.

Also, the uname output doesn't have ny impact on your find command. What type of shell are you in?

Re: Delete Files

Prabhu_7 — Mon, 02 Jun 2003 17:04:49 GMT

Nopes...

I'm not using -exec

This is how i'm giving,

$ find /home/dmeload/CMI -name 'History.dat*' -type f -xdev -mtime +7 exec rm {} \;

$ find /home/dmeload/CMI -name "History.dat*" -type f -xdev -mtime +7 exec rm {} \;

Re: Delete Files

A. Clay Stephenson — Mon, 02 Jun 2003 17:06:02 GMT

in addition to the quotes, you need -exec rather than just exec.

A man find would tell you all of this.

Re: Delete Files

Pete Randall — Mon, 02 Jun 2003 17:06:12 GMT

You need -exec.

Pete

Re: Delete Files

Dario_1 — Mon, 02 Jun 2003 17:06:26 GMT

Raj:

Just add the minus (-) sign before the exec.

Hi Raj:

With regard to "manuals", whether or not you're new to Unix or old friends with it, the man pages are one of the greatest sources of information at your disposal. Don't ever *not* take a minute to look.
