Finding lines not common in both files

[thinkwell]

HI Everyone,

I have a bash scripting question here, that's been giving me trouble.I have two files here with names in them. I need to create two new files by comparing these files.

Each file will have only unique names from the file. In other words, one file contain ONLY unique names in file1. Then the next file contain only the unique names in file2.

file1
############
ruby
heather
ethel
alicia
melody
rosene

file2
############
heather
alicia
carla
ruby
gloria


So when the script has run, I'd have two files - unique1 & unique2.

unique1
############
melody
rosene

unique2
############
carla
gloria

I'd like to stay with bash scripting if at all possible. I've tried the DIFF function, but that outputs all differences to the same file.

Any ideas for me?

Thanks so much,

Dave

grep -v -f file1 file2 > unique2

grep -v -f file2 file1 > unique1


btw, ethel should be in unique1, right?

[thinkwell]

grep -v -f file1 file2 > unique2

grep -v -f file2 file1 > unique1

Now that is just the Cat's Pajamas. Works exactly like I wanted it to. Thanks a million, piwener.

btw, ethel should be in unique1, right?

Um, gulp. Guess that shows why I need a script to do this for me.

Look at the comm command - this is what it's designed for.
