One Liner - Insert Text in File

[simpson]

All,

I am looking for a one-liner to insert text into an ascii file above a line that matches a search.

Example.
I would like to insert a line of text above the line End_of_Section in a file.

Before:

file_a
-------
Start_of_Section
mike
julie
spencer
End_of_Section

After:
file_a
-------
Start_of_Section
mike
julie
spencer
dave
End_of_Section

I would prefer to do this with a one liner. Thanks in advance.
Mike

This sounds like one that could be found in "sed one liners". Just Google for "sed one liners". Here's an example...

Thanks,

I acutally have this one bookmarked along side my Awk one liners and Perl one liners. I just can't seem to solve this "simple looking" problem.

Perhaps not technically a one-liner due to the embedded carriage return, but this is just a straightforward application of the sed insert command:

sed '/End_of_Section/i\
dave' file_A

Annihilannic.
