Merge two files in linux with different column

Question

I have two files in linux, the first file has 4 columns and the second has 2 columns. I want to merge these files into a new file that has the first 3 columns from file 1 an

Answer 1

Not sure which columns you want from each file, but something like this should work:

paste <file1> <file2> | awk '{print $1,$2,$3,$5}'

The first three columns would be picked from file1, and the fourth skipped, then pick the first column from the second file.

Answer 2

If the files have the same number of rows, you can do something like:

awk '{ getline v < "file2"; split( v, a ); print a[2], $1, $3 }' file1

to print colums 1 and 3 from file 1 and column 2 from file2.

Answer 3

paste file1 file2 | awk '{print $1,$2,$3,$5}'

Answer 4

you can try this one without paste command:
awk '{print $1}{print $2}{print $3}' file1 >> mergedfile
awk '{print $2}' file2 >> mergedfile
