There have been a number of excellent suggestions from other people, but it's worth pointing out that sometimes low tech is all you need. I frequently use sed to do things such as replace one domain name with another when a website changes their URL. Short for Stream EDitor, sed is a core part of POSIX and should be available pretty on much every UNIX-like platform imaginable. For non-trivial files it works faster than disk access (i.e. works as fast as a naive file copy). Full regexp support is available. sed 's/www.example.net/example.com/gI' < IN_FILE > OUT_FILE Will stream IN_FILE to OUT_FILE replacing all instances of "www.example.net" with "example.com" cheers stuart -- Stuart Yeates Library Technology Services http://www.victoria.ac.nz/library/
