Author: Darrell May Contributor: jason (jblakey@frogboy.net) Problem: You want to perform a search and replace on a text file. Solution: Here is a perl command I received from a post on the Experienced User Forum. Thanks Jason :-> |

In the example shown below I want to open
the file named /root/test.txt, search for the word e-smith
and replace it with the word mitel. In addition, the
command creates a backup of the original file with the extension .bkup.
In this case it creates /root/test.txt.bkup.
perl -n -i.bkup -e 's/e-smith/mitel/i; print;' /root/test.txt |
