How to print all lines of a data file in reverse order

The command “tac” (reverse of cat command) which prints contents of a file in reverse order in terms of lines. It can also concatenate multiple files while printing in reverse order.

Sample data file:

[neo@techpulp ~]# cat data.txt
line1: Mango
line2: Apple
line3: Banana
line4: Papaya
[neo@techpulp ~]#

Output of “tac” command on the same data file:

[neo@techpulp ~]# tac data.txt
line4: Papaya
line3: Banana
line2: Apple
line1: Mango
[neo@techpulp ~]#
