aslo how to open a file in shell scripting that has been input as an argument ? (not using cat or vi)

What do you mean "process"? If you mean you want to edit the lines of file, you CAN'T (AFAIK). Not the way you think, unless you want to use the "e" command (or something similar) to do line editing. Otherwise, it is best to use a for loop over a cat command and read the lines, writing to a new file, then replacing the old file with the new file.

hi,

use a for loop over a cat command and read the lines

no! that's UUOC (at least).

while read -r line; do echo "$line"; done <file >newFile
mv newFile file
