[NTLUG:Discuss] sysV script help

[m m]

Chris:

Thanks for the information. I think I want to know the information about 
write the script.
or some one give me a piece of example code?

the code I need can do:

find current ip (i am using dhcp, it changes sometimes)
change the new ip on all text files in a directory
change text on the 3rd line on all files in a directory

thanks in advance.
