Just a quicky question. How would I change one line in a file? I have a comment feature on this journal script I run, and I want to make it possible for editing of comments. I store the messages in a file for that journal entry, and have each comment on a new line, and the various info such as name, date, etc. being split by pipestems (|). So that being said, how would I be able to keep the rest of the file, but reprint the new info for that one line. I know how to splice, but I can't figure out how to reprint that new line if it is in the middle of a file.

open FILE,"+>/path/to/file"; @myfile = ; $myfile[$linenumber_you_want_to_change - 1] = "what you want that line to be"; foreach $line(@myfile) { print FILE "$line"; } close (FILE);
Q for Mark: can you skip the foreach and just print the array directly? I assume so, but decided to be cautious...

Hmm, the code you pasted just wrote the one line that changed to the file, not the rest of the file. I came up with some code of my own, it works, but I am not sure how secure it is: I was going to use the rename(whatever.whatever, whatever.bak) feature, but I couldn't get it to work.
