i have 2 list of hotfix updates from two computers.  I need to compare (working computer) against none working computer.

Is there a script or freeware program that I can use that will tell me what exist in working but doesn't exist in nonworking.  I don't want it to compare the file line for line exact i want it to search and see if it exist in one and not the other.

Thanks!

The following works in Linux and Unix:

Both files must be sorted, then you can use "comm":

sort working > working.sort
sort nonworking > nonworking.sort

comm -2 -3 working.sort nonworking.sort

will show all lines that are only in the first file.

Likewise

comm -1 -3 working.sort nonworking.sort

will show all lines that are only in the second file and

comm -1 -2 working.sort nonworking.sort

will show all lines that are common to both files.

For Windows, there is e.g. "winmerge":
http://winmerge.org/

A "comm" implementation is shipped with MobaXterm:
http://mobaxterm.mobatek.net/

This tool is also an SSH/telnet/rsh client and an X-server, based on BusyBox.
It comes in a single portable exe file which works out of the box.

A great free tool for this at http://winmerge.org/

Just take the two text files you want to compare, sort them (can use the command line SORT tool) and then compare the sorted outputs.

I believe the solid freeware editor Notepad++ also has a "compare" mode where you can see the differences between two files.  Again, you want to do that after sorting each.
