Hi, I made a script to control some ip rules with iproute2, but in the execution of the script sometimes I get the "Segmentation Fault" error message. In the script I use other busybox-builtin-tools like sed and awk to read and modify a configuration file, then the script executes the ip command.
I use a few variables in the script. I read in the Internet that this error is because of someone is trying to touch invalid memory possitions, eihter ash, awk, sed or ip.
Could anyone help me?

please post the script.
