📋 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 :
