 |
|
What's a good way to do a locate for a file and exclude all the matches for /usr/portage/
I was hoping that the code below would do the trick:
| Code: | | locate qmail | grep --exclude='/usr/portage' |
but that doesn't work.
Cheers,

Since locate just scans a database rather than you entire system in realtime, you just have to make the database not scan that directory
There is a file in /etc called "updatedb.conf" if you configure it such (see below" when you run "undatedb" (this is run daily in a CRON job) it will make a new slocate database and then it now omits all those directoried
| Code: |
root@Fluid etc # cat updatedb.conf
# Copyright 1999-2004 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: /var/cvsroot/gentoo-x86/sys-apps/slocate/files/updatedb.conf,v 1.13 2004/10/04 04:33:31 vapier Exp $
# This file sets environment variables which are used by updatedb
# filesystems which are pruned from updatedb database
PRUNEFS="NFS nfs afs proc smbfs autofs auto iso9660 devfs tmpfs ramfs ncpfs sysfs supermount devpts usbfs cifs nnpfs subfs udf ntfs"
export PRUNEFS
# paths which are pruned from updatedb database
PRUNEPATHS="/tmp /var/tmp /usr/portage /usr/src /var/db /mnt /var/tmp /proc /sys"
export PRUNEPATHS
# netpaths which are added
NETPATHS=""
export NETPATHS

I imagine there's a million ways to do this, but here are a couple simple ones,
| Code: | locate qmail | grep -v '/usr/portage'
locate qmail | sed -e 's/.*usr\/portage.*//' | cat -s |
I'm sure there's a nice way of making sed strip empty lines, but I don't know it ... I only use sed for simple things.

cool-
| Code: | | locate qmail | grep -v '/usr/portage' |
did the trick. I should have combed the man file a fourth time as it clearly says:
| Quote: | -v, --invert-match
Invert the sense of matching, to select non-matching lines.
|
The /etc/updatedb.conf link is also helpful. I'll add portage to it after the grep -v param etched into my brain.
Thanks again, |
