I'm trying to fill a Perl array with a list of file names in a directory,$dir, and I want to exclude directories. My code is:
my @lsArray = `ls -p $dir | grep -v '/$'`;
But it creates this error:
sh: -c: line 0: unexpected EOF while looking for matching `''
sh: -c: line 1: syntax error: unexpected end of file
I cant seem to find a combination of quotes which does this correctly. Thanks....
Why are you using backticks for something that perl can do perfectly fine on its own?
my @files = grep !-d, <$dir/*>;
Btw, your error is that $' is a perl predefined variable (postmatch) that gets interpolated, so the closing ' is missing.
If you had used
use strict;
use warnings;
Perl would have told you what the problem was:
Use of uninitialized value $' in quoted execution (``, qx) at ...
Always use those two pragmas: Errors do not get less difficult to handle because you don't know about them.
