I find myself looking for the location of a file and then executing some command on the result often. This short script automates the commonly used options.

Executes some sort of find command specified in %find to locate a file then executes a command on the result of that find.
e.g. 

1> pmpath Text::Balanced
/usr/local/lib/perl5/site_perl/5.6.1/Text/Balanced.pm
2> vi /usr/local/lib/perl5/site_perl/5.6.1/Text/Balanced.pm

[download]

(or alternatively) 

1> vi `pmpath Text::Balanced`

[download]

becomes 1> pvi Text::Balanced

# install this as e.g. wvi, then link other files to it.
