Bug

Many thanks SanjayLinux, Klashxx & ghostdog74 for your replies.

Sanjay - too true - I used to remember using sed many years ago. Just been too long now. Smilie

Klashxx - thanks for the perl example, though my requirement isn't a case of plain substitution; rather replacement of the entire line. Smilie

ghostdog74 - yep a while has past since I first joined the forum. Was surprised I could even remember my UID & PWD for the site. Unfortunately because of my involvement in PCI and ISO work, I've not had much opportunity for sometime or a reason to use sed, let alone look at awk. Smilie

I was able to perform what I wanted to do via the command line, but would like to know how can I contain the following to a single-line command statement ??

$ sed '
> /^user/ c\
> user **** ****
> ' temp.txt


INPUT FILE:
user UID1 PWD1
user UID2 PWD2
user UID3 PWD3
get blah-blah-blah
close
bye

OUTPUT:
user **** ****
user **** ****
user **** ****
get blah
close
bye

Thanks in advance if you are able to assist with my query.

Cheers,
Cameron
