I have text file's containg many rows and about 8 columns

on the 3rd column their is time

Is there a utility that will merge this file according to this column

so if i have 2 files

624?????.xyz and 624?????.abc
gives one big file

624?????.def

thnks

you might consider looking into 'sort' and 'comm'.

What exactly do you mean by 'merging'?

could you provide a couple sample files xyz and abc AND the desired result, pls!

there are 3 files (u can open with notepad)

62401018.a + 62401001.b==62401018.sch

third column is the time , if it exist in a it should not pickup from b and go to
the next line

I know very well sql,html and a little bit of asp and learning


thanks
