Hi, I'm very new to scripting.
grep $s $filename | awk '{print $2}' | cut -c 1-8
How can I optimize this using a single awk?
I tried:
awk '/$s/ {print $2}' $filename | cut -c 1-8
However didn't work, I think the awk is not recognizing $s and the verbal is something else. (6 Replies)

This may just be a lack of experience talking, but I always assumed that when possible it was better to use a commands built in abilities rather than to pipe to a bunch of commands. I wrote a (very simple) script a while back that was meant to pull out a certain error code, and report back what... (4 Replies)
Hello,
I trying to extract text that is surrounded by xml-tags. I tried this
cat tst.xml | egrep "<SERVER>.*</SERVER>" |sed -e "s/<SERVER>\(.*\)<\/SERVER>/\1/"|tr "|" " "
which works perfect, if the start-tag and the end-tag are in the same line, e.g.:

tgt-setup-lun
tgt-setup-lun(8) System Manager's Manual tgt-setup-lun(8)NAME
tgt-setup-lun - creates a target, adds a device to the target and defines initiators that can connect to the target
SYNOPSIS
tgt-setup-lun -d device -n target_name [initiator_IP1 initiator_IP2 ...] [-h]
DESCRIPTION
Starts tgtd if necessary and creates a target according to the supplied target_name. The format of the target name is as follows:
iqn.2001-04.com.<hostname>-<target_name> The target name must be unique.
The script then adds the requested device to the target. If specific IP addresses are defined, it adds them to the list of allowed initia-
tors for that target. If no IP addresses is defined, it defines that the target accepts any initiator.
EXAMPLES
Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81:
tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81
Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81 and 192.168.10.82:
tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 192.168.10.82
Create a target that uses /dev/sdb1 and allows connections from any initiator:
tgt-setup-lun -d /dev/sdb1 -n my_target

tgt-setup-lun -h
