I am trying to initialize a file name in bash but not having much luck. For example, one of my bash scripts outputs a file named "FILE_1000G.vcf". I would like to rename FILE to match with the user's name. This is my code:
The script prompts the user for their name. Say the user inputs John. The desired output woud be John_1000G.vcf
I keep getting the following error:
Global symbol "$filename" requires explicit package name (did you forget to declare "my $filename"?) at (user-supplied code).

taken into account.
