How to get your IP-address:
ifconfig "eth0"|grep 'inet addr'|cut -d' ' -f12|cut -c6-20
and if you want to use IP-address at your own scripts just use:
INTIP=`ifconfig eth0|grep 'inet addr'|cut -d' ' -f12|cut -c6-20` echo "$INTIP"
and now you have your IP-address on $INTIP enviroment and you can use that at your scripts.
If you want easy to change which interface IP-address you want to get just example do:
#!/bin/sh INT="eth0"; INTIP=`ifconfig $INT|grep 'inet addr'|cut -d' ' -f12|cut -c6-20` echo "$INTIP";
