UNIX for Dummies Questions & Answers

Hi all,

I am a beginner and I was hoping you can help me out.

I am doing some PDF cleanup and I am looking for a command to search for all PDFs in a certain folder that are older than 2008 for example.

This is what I have so far:

Code:

find ./ -mtime +500 -name '*.pdf' >/test/results.txt

Would the above do it? obviously I would need to change the 500 to the correct number. Is there a way to specify the 2008 in the command?

Thanks,
Zig

Try this:

Code:

touch -m -d "2008-01-01 00:00:01" /tmp/file
find ./ \( ! -newer /tmp/file \) -name "*.pdf" >/test/results.txt

Thanks Xor

I am trying to clean up old/orphaned pdf files. I was wondering, is there a way I can run a grep while the find is running to search if each returned file name is linked from an HTML page?

I think I know how to do them individually but not sure how to do both at the same time.

Code:

find ./ -mtime +1460 -name '*.pdf'

find ./ -name '*.html' -exec grep -l 'filename' | grep :0$ {} \; 2>/dev/null 1>/test/results.txt

Thanks,
Zig

Please post what Operating System and version you are running and what Shell you use. There is some variation in the unix "touch" command and there is a lot of variation in the "find" command.

You might want to read this thread with a short explanation about how to combine various clauses of find. The thread deals with exactly your problem, btw..

I hope this helps.

Thanks for the link bakunin

On second thoughts you can write the output of the first "find" to an intermediate file and then use "grep -f" to read the patterns you search for from this file. Have a look at the man page of "grep" and look for the "-f" option, which is required by POSIX, so it should be there.

I hope this helps.
