#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
