Replace the file name with $1, which means the first argument, or $* to mean
all of the arguments (that way the grep runs over more than one file, if
provided).

You could save a lot of time and processes by using egrep, and all the 'grep
-v' into one expression, delimited by '|', i.e.

egrep -v '@$|bomb|\!|\+\+|crippled' (etc)
