Your solution to fixing the problem is in answering this question.

How do you execute an external command and capture its output?
hint: what are you doing with the date command?

There is no valid reason to spawn 2 shell commands just to get the desired filename.

the bigest problem i am having with this is the file naming part. When the application that creates the file in the first place names it it is TGfollowed by the day then the hour then the minutes then the seconds which looks like this
tg02115413.doc the only referance that matters for my search is the tg and the day as i want to cron this and have it run automaticaly in the unix .sh the format would be tg`date +%d*`.doc but perl does not seem to like that from what i have read perl used mday for the day so how would i have this work in perl syntax

The verbose and not very portable method:
Expand|Select|Wrap|Line Numbers
  1. my $date = `date +%d`;
  2. chomp $date;
  3. my $name = "/home/grimp/tg$date.doc";
The Perl way:
Expand|Select|Wrap|Line Numbers
  1. use POSIX qw/strftime/;
  2. my $name = strftime("/home/grimp/tg%d.doc", localtime);
