Go easy on yourself, and :
a) don't try to match the quotation marks verbatim. Instead, match them with simply a .
b) use parenthesis to 'remember' a pattern that you don't want to have
to specify again.
E.g. to replace the path on the right-hand-side, do this:
(i replaced it with a /; you could of course replace it with whatever
you want)
perl -i -ne 's/(^\s*\$conf\[.nagios_base.] = ).\/nagios\/cgi-bin.;/$1 \"\/\";/; print;' phpConfigFileName
E.g. to delete the line outright:
perl -i -ne 'print unless /^\s*\$conf\[.nagios_base.] = .\/nagios\/cgi-bin.;/;' phpConfigFileName
Cheers,
Jon
