I have 2 large file (.dat) around 70 g, 12 columns but the data not sorted in both the files.. need your inputs in giving the best optimized method/command to achieve this and redirect the not macthing lines to the thrid file ( diff.dat)


File 1 - 15 columns

sample look-

Code:
2036|001|021|92|570|2|422|1|0|0|0|570|0|0|12

Field separate - "|"

File 1 Size ( 60 G)
File 2 Size ( 61 g)
Note - data is not in the sorted order ( file1 and file2)

Requirement, I need to find the not matching lines and redirect those to new file "differnce.dat"

what constitutes "non-matching" lines?
Entire line or some key fields in file1 and 2 to match on?
You have to be clearer with your requirement statements.

Also, please use code tags when posting code/data samples.

look into man grep with options -F and -f.
Or man fgrep

grep -F -x -v -f file2 file1 ?? or any other optimization command
