I\'ve started using Vim to develop Perl scripts and am starting to find it very powerful.
One thing I like is to be able to open multiple files at once with:
To add to the args list:
args
:argadd
To delete from the args list:
:argdelete
In your example, you could use :argedit test.pl to add test.pl to the args list and edit the file in one step.
:argedit
:help args gives much more detail and advanced usage
:help args
