Code:
grep -v -f fileA fileB

NAME
findrule - command line wrapper to File::Find::Rule USAGE
findrule [path...] [expression] DESCRIPTION
"findrule" mostly borrows the interface from GNU find(1) to provide a command-line interface onto the File::Find::Rule heirarchy of modules. The syntax for expressions is the rule name, preceded by a dash, followed by an optional argument. If the argument is an opening parenthesis it is taken as a list of arguments, terminated by a closing parenthesis. Some examples: find -file -name ( foo bar ) files named "foo" or "bar", below the current directory. find -file -name foo -bar files named "foo", that have pubs (for this is what our ficticious "bar" clause specifies), below the current directory. find -file -name ( -bar ) files named "-bar", below the current directory. In this case if we'd have omitted the parenthesis it would have parsed as a call to name with no arguments, followed by a call to -bar. Supported switches I'm very slack. Please consult the File::Find::Rule manpage for now, and prepend - to the commands that you want. Extra bonus switches findrule automatically loads all of your installed File::Find::Rule::* extension modules, so check the documentation to see what those would be. AUTHOR
