awk case-insensitive
can I tell awk to be case insensitive for one operation without setting the ignorecase value ?

thanks,
Steffen

You cannot use IGNORECASE to make certain rules case-insensitive and other rules case-sensitive, because there is no way to set IGNORECASE just for the pattern of a particular rule.
To do this, you must use character sets or tolower.
However, one thing you can do only with IGNORECASE is turn
case-sensitivity on or off dynamically for all the rules at once.

I know I cannot use IGNORECASE for only certain commands, only globally.

I didnt want to IGNORECASE anyway. My problem is that I have to look for a match in a file using awk and the search string is a variable. Since I cannot control if the variable is lower or upper case, I need to have awk search for any lower or uppercase match(es).

if you are searching for word "goat" use this
/[Gg][Oo][Aa][Tt]/

I know that, but I have a user input variable as the search string, I cannot alter the variable to [Aa][Bb][Cc].....

tolower/toupper
Why not use the functions tolower()/toupper() functions in awk. That might help you.
