Need to replace line of text.

[aenagy]

I have a text file with configuration information in the form:

etc
parameter1 some default text supplied by the vendor
etc
parameter2 some more default text
etc

What I would like to do is replace the entire line with parameter1 with my own text. The problem is that I would like a solution that can match the line with "parameter1" as the first word on the line, but replace all of the text after it with something I provide. I could klugde something together with a Bash script and looping, but I was hoping for a more elegent solution, and I would rather not resort to

What I would like to have as output is:

etc
parameter1 my own text here
etc
parameter2 my other text here
etc

Suggestions would be appreciated.

Thanks.

Hi,
You can do this with Perl and it can be elegant depending on your skill or just write it in C.
Just a question, for such things why do you want elegance, if I may say so it is not doing anything complex and if it is for you just write it and refine it - play with it until it goes how you want in whatever language you are comfortable with.

You could probably do this in a single line of awk, but I'm feeling a bit too brain dead to figure it out right now (it's been a long day )

Google about awk, and you should be able to figure out a solution quickly enough.
