But I just dont like how Im getting there ... if this aint spaghetti code, I dont know what is ..




#! /bin/ksh
cat seedfile | awk '{print $4}' | while read x
do

snmpwalk -c xxxxxxx $x .1.3.6.1.2.1.47.1.1.1.1.2.1 | sed 's/.*STRING: "//' |
sed -e 's/Cisco Systems Catalyst"//' -e 's/Cisco Catalyst //' |
sed -e 's/Cisco Systems Catalyst //' -e 's/Chassis//' -e 's/System//' |
sed -e 's/ uplinks fixed config.*//' -e 's/, Hw Serial.*//' -e 's/\"//g' -e 's/c
hassis//' -e 's/baseT ports//'
done

Thanks again ...

This really looks like a case for a perl script. perl has a bit of a steep learnign curve but once you've got the basics it dows bits and pieces like this easy-peasy.

I think sed is appropriate for this, although there is no reason to break it into multiple scripts like that. I also removed the "useless use of cat":

[tt]#! /bin/ksh
awk '{print $4} seedfile ' | while read x
do

snmpwalk -c xxxxxxx $x .1.3.6.1.2.1.47.1.1.1.1.2.1 | sed 's/.*STRING: "//
s/Cisco .*Catalyst //
s/ Chassis.*//i
s/ uplinks fixed config.*//
s/, Hw Serial.*//
s/\"//g
s/ baseT ports//'

done[/tt]

I have also removed some redundant searches by using .* in the regex and the /i option at the end of the search to ignore case.
