A shell script is a computer program designed to be run by the Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. A script that sets up the environment, runs the program, and does any necessary cleanup, logging, etc. is called a wrapper.
In this post, we will write a shell script to check if the current year is a leap year or not.
Print “leap year” if the current year is leap year else print “not a leap year”
The following is the shell script to check if the current year is a leap year or not:
leap=$(date +"%Y") echo taking year as $leap if [ `expr $leap % 400` -eq 0 ] then echo leap year elif [ `expr $leap % 100` -eq 0 ] then echo not a leap year elif [ `expr $leap % 4` -eq 0 ] then echo leap year else echo not a leap year fi
$ taking year as 2019 $ not a leap year
