Re: How to filter the contents of two text files.
Some little help is needed here ... I have two text files, each has just a single column of data FileA has 2798 entries, while FileB has 4242 entries; There are entries in FileA that are also in FileB... I'd like to filter against the two files, so I only get those entries in FileB that don't occur only in FileA There are a couple of commands to do exactly what you want. comm(1) -- select or reject lines common to two files http://www.freebsd.org/cgi/man.cgi?query=commapropos=0sektion=0manpath=FreeBSD+6.1-RELEASEformat=html diff(1) -- find differences between two files http://www.freebsd.org/cgi/man.cgi?query=diffapropos=0sektion=0manpath=FreeBSD+6.1-RELEASEformat=html sort(1) -- sort lines of text files http://www.freebsd.org/cgi/man.cgi?query=sortapropos=0sektion=0manpath=FreeBSD+6.1-RELEASEformat=html Enjoy!
