awk removing specific line
Hi,

I have file with lines key=val.
For ex(conf.file):-
Code:
c=3
    ef=78
    b=40
    ca=40

I want to remove the line with c=3, when I execute the below command it's removing both lines i.e c=3 and ca=40. Could you please correct my command.
Code:
/usr/xpg4/bin/awk -v key=c 'match($0,key) == 0 {print $0}'  conf.file

Thanks.

Try: match($1,"^"key"="), or
Code:
/usr/xpg4/bin/awk -F= '$1!=key' key=c conf.file

Code:
awk '{if( $0 !~ "c=.*")print $0 }' infile
