Perl: Stripping last 4 characters from string

Comment:

How do I strip the last 4 characters of a string? I've been trying to use substr, though since the length of what I want returned is variable, I don't get desired results. Let's say I have the following records: AOX.B LVZMZ.B MQZ.Q NQYUZ.B PCZUX.B QFZUZ.B RTW.N SKXVZ.B SYZXV.W UOZUX.N BMZVZ.N VRZ.Q WPZUX.B XOXRP.X YMZMZ.N ZZWMR.N CLXVX.X DHTVZ.X EOYOZ.N FZUVV.N HFNPZ.X IQZXQ.Q I want to strip off the last four characters, and print what's left. It should return the following: A LVZ M NQ PC QF R SKX SYZ UOZ BMZ V WPZ XOX YMZ ZZW CLX DHT EOY FZU HFN IQZ Any hints?

Your answer is in the second sentence of the perldoc for the substr function. perldoc -f substr

Thanks. The info page for substr, was just confusing to me. I got desired results with the following: my $symbol = substr $line[0], 0, -4;
