This is the command NF that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
col1 .. col9, NF - awk and print a column (based on the name of the program, 1-9)
SYNOPSIS
col1 [SEPARATOR]
DESCRIPTION
col1 is a simple script that conveniently splits and prints a given column, where the
column to print is the name of the script program you're running (col1-col9). col2-col9
are symlinks to col1; their behavior simply changes based on the name called.
NF can be used to print the last field.
The program takes one optional argument, the input field separator (whitespace, by
default).
EXAMPLES
Rather than:
mount | awk '{print $3}'
Try:
mount | col3
Instead of:
cat /etc/passwd | awk -F":" '{print $7}'
You can just do:
cat /etc/passwd | col7 :
Or
cat /etc/passwd | NF :
