Adding column
Hello,

I'm struggling with the following problem in sh script:

Adding a column to the right-end of a file ("master-file": non-constant column number, tab and linux formatted) where the column is the 4th one of file1 (space and DOS formatted)
Changing the header of column 4 of file 1 at the same time would be great.

Tanks for help,
Lco

What have you attempted so far and where do you get stuck?

many things, the last one:

Code:
 awk '{getline lin < "$1.analysis.txt"; print lin"\t"S4}' ${ModelName}.fir > $1.analysis.txt

where ${ModelName}.fir is "file1" and $1.analysis.txt "master-file"

Try:
Code:
awk '{printf $0; getline<f; print "\t"$4}' f=file1 masterfile > masterfile.new

Thanks it works.
my final code include removing DOS end of line from file1.

Code:
awk '{printf $0; getline<f; sub(/.$/,""); print "\t"$4}' f=file1 masterfile > masterfile.new
