I'm running some third-party Perl script written such that it requires an output file for the output flag,
Unfortunately, the script appears to require an actual file, that is, users must create an empty file
filename.txt with 0 bytes and then input this empty file on the script command line
perl script1.pl -o filename.txt
Question: How would I create an empty file within a bash script? If one simply tries
perl script1.pl -o filename.txt, the script gives an error that the file doesn't exist.
