From: joinerda on 14 May 2010 14:35 I would like to use a perl format statement to autogenerate qsub files for a PBS scheduler. The files I need to generate are essentially shell scripts with comments beginning with a hash mark to denote them as pragma for the scheduler. If I create a format statement that looks like format QSUBFILE = #PBS -N @<<<<<<<<< $queue .. the line beginning with a hash mark is read as a comment by PERL, instead of a line that needs to be printed that starts with a hash mark. How can I using a PERL format statement generate a number of files all of which has as their first few lines variations of #PBS -N dustfit #PBS -q default #PBS -l nodes=1:ppn=8 #PBS -l cput=6000:00:00

The easiest option is to just add a leading space before the # format QSUBFILE = #PBS -N @<<<<<<<<< $queue . will end up printing exactly what you want but the first column will be empty.

Put the hashmark in a variable Eg) my $hm="#"; format QSUBFILE = @#PBS -N @<<<<<<<<< $hm,$queue . Best Regards, Adam

I forgot to delete your original #. Please correct that to read Eg) my $hm="#"; format QSUBFILE = @PBS -N @<<<<<<<<< $hm,$queue ..

I thought about that, but the file has a space in the line that breaks the way the file is parsed by the scheduler. I need the first character of the line to be a hash. I can do this with print or printf statements easily enough, but I am trying to come up with a solution where the format statement looks as much as possible like the files my end-users (who tend to ask things like "what is backslash n again?") are used to dealing with so that this is easier to do in the future.
