Shell Programming and Scripting

Hi All,
I have a problem in concatenate a file with another file.
The problem is as below:

I have a file with three columns and 7 rows. This is the first file and all separated by tab delimited format.

The second file has 8 colunms and 7 rows. And also separated by tab delimited format.
So now I need the first file with three colunms to come first and than the second file with 8 columns and make a third file of total 11 colunms and 7 rows.

Can any one have any inputs....Its needed in a reporting application.
Thanks in advance...To all masterminds....

look into 'man paste'

Hi vgersh,
Thanks for you input but can you give example!!!!
Like taking two files as input and puting the output of the two into a third file.

I have tried the same but not able to do the same....

It will be helpful if you can do that a simple example...

Thanks and Regards,
Soumya

There have been so many posts describing the usage of paste

> cat a
1 2 3
4 5 6


>cat b
a b c d e
a b c d e

>paste -d" " a b
1 2 3 a b c d e
4 5 6 a b c d e


-d is for delimiter, change accordingly for your case

Thanks...just what i was looking for

Hi

I have two files, one is 1.6 GB, I would like to add one extra column of information to the large file at a specific location. After the 3rd column.

For example:

File 1 has two columns more than 1000 rows like this

MM009987 1

File 2 has dozens of columns like this

MM00098 MM00076 3 4 2 4 2 1 3

I would like to add the 2nd column from File 1 to File 2 after column 3

Thank you for any help on this

this is an old thread.

you said the one of the file is 1.6GB, and file 1 has only more than 1000 rows. So how's it going to look like after the 1000th line of your big file when you have inserted those 1000++ 2nd columns into it?
