When I use "diff" to find the difference between two large data files,
diff A.txt B.txt > dif.info
it is output:
diff:memory exhausted
or add the argument "-H"
diff -H A.txt B.txt > dif.info
it also got the same message:
diff:memory exhausted
The size are about 1.5GB. How to compare large files ? Any other tools or solutions ? my PC: Redhat5.4 OS, 4GB memory. Thanks.
