Grepping on special characters

Last Modified: 2017-11-16

I have a array that has a value with special characters in it and I need to match them.

Example:    @INCOND1 = $EGH0001_#SSSR0002_OK^ODAT^AAA^$EGH0001

The entries are with in an array and I am grepping on a an array where I am matching the value from one array to another array.

$OUTDOCOND = "$EGH0001_#SSSR0002_OK";    Or could be $OUTDOCOND = "$EGH0001_?SSSR0003_OK";

my @answerO = grep /^\Q$OUTDOCOND\E\^/, @INCOND1;

Sometimes the data is not matching even if its in the array.
Tried the \Q and \E but not sure if this is working completely.

The 3 special characters in the array are $ # ?

Not sure if there is another way to \? or \# or \$ the beginning values.
