Hi,

I'm trying to sort through some Squid log files that have been rotated with logrotate. These files are named

access.log
access.log.1.gz
access.log.2.gz
.
.
.
access.log.28.gz


The oldest file is #28 and the newest file is access.log. The individual files are from oldest on the top to newest.

If I'd like to sort through all of these files, I would do something like:

zgrep 'pattern' access.log*

but the order isn't too useful. I've tried

zgrep 'pattern' access.log.[1-2][0-9].gz access.log.[1-9].gz access.log

but the pattern is 10-28,1-9,access.log instead of 28-1,access.log. I've tried writing the order backwards (i.e., [2-1][9-0]) but that doesn't work.

How can I get this to ouput correctly? Do I need to use the 'find' statement or create a shell script of some sort? I've played with

for file in $(ls access.log.[1-9].gz access.log.[1-3][0-9].gz); do echo $file; done

but that doesn't seem to help either.

Thanks,

If you haven't messed with the file's timestamps, there's always
ls -t access*| grep <whatever>

Thanks for the reply. However, that doesn't seem to do it. The sort doesn't sort it in reverse numeric form. The command

ls access* | sort -n

results in:

access.log
access.log.10.gz
access.log.11.gz
access.log.12.gz
access.log.13.gz
access.log.14.gz
access.log.15.gz
access.log.16.gz
access.log.17.gz
access.log.18.gz
access.log.19.gz
access.log.1.gz
access.log.20.gz
access.log.21.gz
access.log.22.gz
access.log.23.gz
access.log.24.gz
access.log.25.gz
access.log.26.gz
access.log.27.gz
access.log.28.gz
access.log.2.gz
access.log.3.gz
access.log.4.gz
access.log.5.gz
access.log.6.gz
access.log.7.gz
access.log.8.gz
access.log.9.gz


Using 'sort -rn' just reverses this list but doesn't group it from highest number to lowest.

Thanks.

Ah, that's true. Thanks.

If you think of another solution, I'd appreciate that as well.

Thanks again,

Sorry. A little more complicated than I thought. Try this:

Thanks. With a minor change: it worked.
