Hi,

I have two text files.The first and the 2nd file have data in the same format
For e.g. The first file has
table_name1 column1 sum(column1) max(column1) min(column1)
table_name1 column2 sum(column2) max(column2) min(column2)
table_name1 coulmn3 sum(column3) max(column3) min(column3)

table_name2 column1 sum(column1) max(column1) min(column1)
table_name2 column2 sum(column2) max(column2) min(column2)
.
.

The 2nd file has the same data but few additional columns might be present in it.

I need to compare the values of both the files for common columns and report the mismatches to a separate file.
I am new to unix. Can anyone tell me how to do this?
