i've got a little script to connect my pc to the internet. due to I'm using ip-masquerading, I have to run a script for the ipchains-rules. my problem: when I run this script which sets the rules for ipchains just after I gave the command to connect to my isp, I have no IP-adress. so i have to run this script for a second time, after about 3 seconds (I'm using ISDN). now I wanna ask, if there is a bash "delay"-command. It have not to be exactly. about 3 or 5 seconds on a pentium 100.
