Vim: execute current file?

Question

If I have a file with a shebang line (e.g. #!/bin/bash) open in Vim and the file has execute permissions (i.e. chmod +x) I know I can type this to exec

Answer 1

When starting vi, specify file path explicitly, like this "vi ./blablabla"

vi ./yourscript.pl

After that start at anytime with only :!%

The other variant is to invoke the vi command like this

!./%
