in reply to pattern match a name from stdin

First: You should probably chomp $file.

Secod: if $file contains any metacharacters, they will need to be escaped (see quotemeta).

Third: If you are testing for the presence of a literal sting within another sting you may be better off with index (in which case disregard the use of quotemeta)

They say that time changes things, but you actually have to change them yourself.

this now works: `if (m/\\|\Q$file/) {print $num_entry};` [download] However, if i want the match to occur at at the end i would include an addition $ `if (m/\\|\Q$file$/) {print $num_entry};` [download] For example if the user entered Sarah it could output Sarah and Sarah-jane. But this second bit of code doesnt seem to work?	[reply] [d/l] [select]

The \Q is making the '$' match a literal '$'. You want `m/\Q\|$file\E$/`, methinks. Jeff `japhy` Pinyan, P.L., P.M., P.O.D, X.S.: Perl, regex, and `perl` hacker How can we ever be the sold short or the cheated, we who for every service have long ago been overpaid? ~~ Meister Eckhart	[reply] [d/l]
