Need another detail. In our source file, we used to receive '~^' as delimiter, through the script we will replace this with 'ACK' ('\006'). Could you please provide the how the above command can be used for the delimiter '~^'. Need to know the hexadecimal value for this delimiter '~^'

Thanks & regards
Srik
Something like this?
Code:
awk '{gsub("~^","\006")}1' file > newfile
