Unix shell embedding Awk?
Surely you can check an environment variables value in the shell, without the need to call Awk. As it stands, it doesn't seem to be a good example of using the Unix shell. --Paddy3118 07:59, 11 September 2011 (UTC)
- We cannot check for substrings on a Bourne shell, so we have to use AWK. Other shell implementation may not need to do this of course. Markhobley 08:02, 11 September 2011 (UTC)
- Actually, it looks like you can match substrings by using the switch command. If this works I will try and rewrite this to get rid of awk. Markhobley 08:20, 11 September 2011 (UTC)
