Hi All,

I want to change a string say "old_fieldname" to "new_fieldname" in all the files where old_fieldname is present.

do I have to use find command ??

1. yes, if your files are spread around the file system
2. no, if your files are located in the same directory

which case - 1 or 2?

I think a better forum for questions like this might be UNIX Scripting Forum.

But... you'll have to investigate: find, sed, ex [and maybe awk].

It also might be helpful to see your sample text file.

Good luck.
