Grepping on special characters
Hi
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
$EGH0001_?SSSR0003_OK^ODAT
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.
Thanks
Mike

Quote and Quote-like Operators
While we usually think of quotes as literal values, in Perl they function as operators, providing various kinds of interpolating and pattern matching capabilities. Perl provides customary quote characters for these behaviors, but also provides a way for you to choose your quote character for any of them. In the following table, a {} represents any pair of delimiters you choose.
Customary Generic Meaning Interpolates
'' q{} Literal no
"" qq{} Literal yes
`` qx{} Command yes*
qw{} Word list no
// m{} Pattern match yes*
qr{} Pattern yes*
s{}{} Substitution yes*
tr{}{} Transliteration no (but see below)
y{}{} Transliteration no (but see below)
<<EOF here-doc yes*
