case statement in a case statement

thijs lankhorst_1 — Wed, 05 Apr 2006 04:32:03 GMT

Hi there. Can anybody tell me if i can use a case statement in a case statement?

For example in the following script i get a syntax error but i am pretty sure its caused due to the fact that it doesnt like the case into case statement: (see attachment)

Any comments are much appreciated.

You have to ;; in second case statements.

#!/bin/ksh

echo "What LAN card would you like to adjust: "
read card

case "$card" in

[Ee][Tt][Hh]0)
lc=eth0
;;
[Ee][Tt][Hh]1)
lc=eth1
;;
[Ee][Tt][Hh]2)
lc=eth2
;;
[Ee][Tt][Hh]3)
lc=eth3
;;
[Ee][Tt][Hh]4)
lc=eth4
;;
[Ee][Tt][Hh]5)
lc=eth5
;;
[Ee][Tt][Hh]6)
lc=eth6
;;
*)
echo "Wrong LAN card, exiting"
exit 1
;;
esac

spe=`ethtool $lc | grep -i speed | awk '{print $2}'`
dup=`ethtool $lc | grep -i duplex | awk '{print $2}'`
neg=`ethtool $lc | grep Auto | grep -v autog| awk '{print $2}'`

echo "Current settings are:"
echo
echo "Card speed(S) is: $spe"
echo "Mode(M) is: $dup"
echo "Speed Negotiation(SN) is: $neg"

echo
echo "What would you like to change (S/M/SN): "
read choice

case "$choice" in
[Ss])
echo "What card speed(10/100/1000) would you like?: "

case "$cs" in

ethtool -s $lc speed 10 duplex $dup autoneg $neg

ethtool -s $lc speed 100 duplex $dup autoneg $neg

ethtool -s $lc speed 1000 duplex $dup autoneg $neg
;;

echo "Incorrect speed, exiting"
exit 1

ethtool -s $lc speed $spe duplex full autoneg $neg

case "$an" in

esac

exit 0

## END ###

# ADDED gives new lines added.

Your greetings are more valuable than points ;)

A tip to you: Use sh -x <script> to get debugging informations always.

Keep posting.
