Find and Replace

[webdev17]

I'm trying to find a specific phone number in a group of files and replace it with a new phone number. Is there a way to do this with a unix command?

Thanks!

man sed, specifically something like:

/old_tel_no/c\
new_tel_number

Put this in a file (for example sedscr). Then use

sed -f sedscr filename > new_filename

to write the new details into new_filename. You can rename new_filename to the original later if preferred. I think gnu sed has an option to edit in-place (Feherke make be able to confirm).

Regards.
