I have a log file with thousands of lines, some of those lines come in with garbage /
binary data in them. The lines with that happening are junk and of no use to me I want
to pattern match for the junk and simply do nothing with that line, all other lines
get divided into 2 different output files.
The code that I have below will separate the lines into output files but does not take
into account the garbage.
# Split the lines into the appropriate files.
while (<LOGFILE>) {
if ( (/JUNIPER/)||(/REDBACK/) ){
print DSL $_ ;
} else {
print DIALUP $_ ;
}
}
I have included one good line and one garbage line in this post, be aware though that
outlook and other mail clients will convert the control characters in the garbage to
single characters so the garbage lines below is not 100% accurate but you should get
the jist.
