#Leif Messinger
#For when you want to search a lot of words in a file fast

#Arg 1 is the argument the list of words you want to search
#Arg 2 is the file you want to search

#-z means that it looks at the file as a whole, just treating newlines a characters.
#-r is regex. Needed for $, even tho the documentation says you don't need it. They are liars.
#First command replaces all . with \. and all - with \-
#Second command takes all newlines and replaces them with )|(
#Third command takes the trailing |( and deletes it
#Forth command puts a /( at the start
#Fith command puts /!d at the end. This tells it to not delete any lines that match the pattern.

#The second sed takes the output of the first sed as a command that searches any of the combined words
#-f - takes a command from the input
sed -z -r -e 's/\./\\\./g ; s/\-/\\\-/g' -e 's/\n/\)\|\(/g' -e 's/\|\($//' -e 'i/\(' -e 'a/!d' $1 | sed -r -f - $2
