uncaught exception

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Can you please tell me why the following line gives me an uncaught exception from user code due to syntax error on this line? $temp = "grep \"synopsys translate_\" *.v | awk -F ":" '{print $1}' | uniq "; Execution of test.pl aborted due to compilation errors.

You have unquoted double quotes in your command. I recommend using the `qq{}` operator (if variable interpolation is really what you want): `$temp = qq{grep "synopsys translate_" .v \| awk -F ":" '{print $1}' \| +uniq}` [download] but note that `$1` will be interpolated by Perl. If you don't want that either, don't use double quotes. I recommend the `q{}` operator: `$temp = q{grep "synopsys translate_" .v \| awk -F ":" '{print $1}' \| u +niq}` [download]	[reply] [d/l] [select]
