Question

I need to select for example:

• Column 2 of row 7.
• Column 3 of row 8.
• Columns 1 and 3 of row 11.

of a specific file and place the result in another file.

This is what I have tried so far:

sed -n -e '7p' -e '8p' -e '11p' Old_File | awk '{printf("%s %s %s\n", $2, $3, $1);}' > New_File. 

Answer 1

Awk alone can get it done:

awk 'NR==7{print $2} NR==8{print $3} NR==11{print $1, $3}' Old_file > New_file
