in reply to
opening files where name is a concatenation of variable
open (OUTHANDLE, ">$basedir . /output/file.txt") or die ;
You're trying to open a file that doesn't exist.
perl -le 'print ">$basedir . /output/file.txt"'
results . /output/file.txt
There's no concatenating operator there, you clobber them all in one single string, the $basedir
, the dot with spaces ( .
), and /output/file.txt
. Should you use $!
variable, Perl would tell you what was wrong.
my $basedir = "results";
my $filename = "$basedir . /output/file.txt";
open (OUTHANDLE, ">$filename") or die "can't open ($filename): $!\n";
can't open (result . /output/file.txt): No such file or directory
You actually want,
open (OUTHANDLE, ">$basedir" . "/output/file.txt") or die $!;
but this is not good although it probably works. Use suggestions from other replies.
