cutting out chunks of a file based on variables 1

[stanhubble]

I am trying to automate the removal of some chunks of a smb.conf file using awk. I need it to match on some constant text combined with an environment variable. what i have so far:

awk -v pattern="text"$ENVVAR 'BEGIN { RS = "[" }
!/^pattern/ { print "["$0 }' ./smb.conf

i think my problem is the ^ combined with the variable, if i just use hard coded text it works fine.

???

I don't think variables are recognised between the // regexp delimiters.

Try this:

[tt]awk -v pattern="^text"$ENVVAR 'BEGIN { RS = ORS = "[" }
$0 !~ pattern { print }' ./smb.conf[/tt]

Sorry, I'll just tidy that up a little:

[tt]awk -v pattern="^text"$ENVVAR '
BEGIN { RS = ORS = "[" }
$0 !~ pattern
' ./smb.conf[/tt]

Thanks Anni

worked like a charm.
only problem is an extra [ at the end of the file, but that should be easy enough to clean up
