/home/prog/bug/ant
/home/prog/bug/make
/home/prog/bug/gen
/home/prog/bug/tiff


file2
/home/prog/bug/make
/home/prog/bug/gen

i want a output file which should contain

Code:
file1-file2
/home/prog/bug/perl
/home/prog/bug/ant
/home/prog/bug/tiff

My code

Code:
cat file1 file2 > temp
sort temp > /dev/null
uniq -u temp > file3
rm -f temp

but i didnt get the required output. I am using tcsh.

So i need some idea to write this script.
