a few approaches: IPFORW=`cat /proc/sys/net/ipv4/ip_forward` # ^^^ no spaces I assume * if [ $IPFORW == 0 ] ; then echo "off"; fi # ^^^ the $ sign * if (test $IPFORW = 0); then echo "off"; fi # You might also come along without a variable: * if [ `cat /proc/sys/net/ipv4/ip_forward` == 0 ] ; then echo "off"; fi or totally different: * if (/bin/grep 0 /proc/sys/net/ipv4/ip_forward -q) ; then echo "off"; fi - -- Weasel http://www.cosy.sbg.ac.at/~ppalfrad/ PGP encrypted messages prefered.
