Re^4: Wildcard in a hash

thanks, but in the loop of read input file, "if ($pins1 =~ /^$key$/) ", the dollar sign, $ will have to be removed too. I forget to mention that for the pins/ports name, it has expression like this symbol, [], which means that it cant be cathed when using ur way. This is the only weak point.

For example, c4a_123[3]

thanks, but in the loop of read input file, "if ($pins1 =~ /^$key$/) ", the dollar sign, $ will have to be removed too. This applys only if you want a partial match of the keys. A key like `c4a` would then match `c4a_123[3]` also. You could escape the brackets: `$pins2 =~ s/\/./; # make key into regex string if containing * $pins2 =~ s/([\[\]])/\\$1/g; # escape brackets c4a_123[3] -> c4a_1 +23\[3\]` [download] That way the brackets aren't treated as a character class whilst matching the keys. perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'	[reply] [d/l] [select]
