Replace a field in a file.

Hi all,

I need to replace a field of a line with another pattern.The field can be empty also.
There are 2 files file1 and file2.
By refering file2 , I need to replace 5th column of file1 .
I can replace if the field is not empty .But when its emtpy ,I am finding difficulty to replace as there can be other fields also empty.So I need to replace according to the position.

Could you please help me to resolve this.

Regards
Muktha

Not alot of info here, but....

You could use the 'join' command and take the fields you want from file 1 or f2 (in any order) and then send the output to a new file.

It has options not only to create a new file with the fields in any order, but it also has the -e option that might be beneficial to you.

man join
