egrep read file?

type8code0 · 03-19-2011, 11:42 PM

Hi all,

Is it possible for egrep or zcat to read from file?

Example:-

I'm trying to find a few ip addresses in different log files. Problem is the list of ip addresses is quite big. Ip addresses that I use below are just for an example.

Code:

zcat logfile.1.Z logfile.2.Z | egrep 10.10.10.10 10.10.10.11 10.10.10.12 > output

Is it possible to do something like this?

Code:

zcat logfile.1.Z logfile.2.Z | egrep [read from file, let say “iplist”] > output

Code:

zcat logfile.1.Z logfile.2.Z | egrep [iplist] > output

Code:

cat iplist
10.10.10.10
10.10.10.11
10.10.10.12

or

Code:

zcat [read from log files, let say “logs”] | egrep [read from file, let say “iplist”] > output

Code:

zcat [logs] | egrep [iplist] > output

Code:

cat logs
logfile.1.Z 
logfile.2.Z

Have a look at the manpage for grep - while you're at it, check out zgrep.

Thanks syg00, unfortunately, zgrep is not install in the system.

Code:

SunOS{type8code0}: grep
Usage: grep -hblcnsviw pattern file . . .

SunOS{type8code0}: whereis grep
grep: /usr/bin/grep

SunOS{type8code0}: zgrep
bash: zgrep: command not found

SunOS{type8code0}: whereis zgrep
zgrep:

I gave a Linux answer as you posted in a Linux(sub-)forum.
A quick check shows my (old) OpenSolaris guest is broken, so I can't check the commands. Best maybe to request this thread be moved to Solaris (click on the "Report" button on your original post).

Moved: This thread is more suitable in Solaris/OpenSolaris and has been moved accordingly to help your thread/question get the exposure it deserves.

According to this, Solaris' grep also has the -f "read patterns from file" option.

Indeed.
I managed to find a boot environment for my OpenSolaris that works. Being aimed at Linux users it has egrep that I am familiar with, but the xpg4 version does also work the same.
