replacing specific lines in a text document

stellarmarine1 · 09-07-2004, 01:49 PM

Is there a way to write a script that would overwrite specific lines in a text file. For instance I would like to change the 1st and 4th line in a text file. How would I go about doing this while incorporating it into a script?

I hate to keep asking all these script writing questions. But it seems that there are so many tutorials out there that I don't know which one to follow.

Any suggestions?

man sed

sed -e 'n c <text>' <file>

Where n is the line-number, c the sed command,
<text> the text you want to be on the n'th line.

Cheers,
