To append last word of the line
Hi All,
I need to append the last word of a line to the same line inside a file.
For example::
Below are the contents inside an input file
Code:
A/B/C
D/E/F

Output file should be::

Code:
A/B/C/C
D/E/F/F

Regards,
$(NF+1)=$NF creates a new column ($NF+1) with the value of the last column $NF.

The statement $(NF+1)=$NF is a condition without braces. Since the condition is true, awk prints the current record per default.
