 how to substutue string in a text file by using "gerp" or "find"?

I have a text file, lof of "abdfggg" in that text file, i need to change
it to "opsmsdd", is there a simple way to do that?

sed is your friend.

sed 's/abdfggg/opsmsdd/g' <infile> > <outfile>

That will replace ALL instances of abdfggg with opmsmdd in file infile, and write it to outfile.

Be sure that the redirect goes to a new file. If you try to redirect it back into the original file, you'll be hosed after the first line.

Cheers!
