I was doing the lab of the month number which is:
" Develop a shell script
/home/bob/print-month-name.sh that accepts the number of a month as input and prints the name of the respective month. eg
./print-month-name.sh 1 should print
./print-month-name.sh 5 should print
May . Also keep these in mind.
- The script must accept a month number as a command line argument.
- If a month number is not provided as command line argument, the script must exit with the message
No month number given.
- The script must not accept a value other than
12. If not the script must exit with the error `Invalid month"
So I created this script, but I want to know if it is valid or not, I already saw the solution and I saw some diference only in the logic, I think maybe when I nest the if inside other if, I am creating the error but I am new on this, please can you check it and tell me if it is correct?
My script is:
A=$1 if [[ A -gt 1 && A -lt 13 ]] then if [ A -eq 1 ] then echo "January" elif [ A -eq 2 ] then echo "Febrauary" elif [ A -eq 3 ] then echo "March" elif [ A -eq 4 ] then echo "April" elif [ A -eq 5 ] then echo "May" elif [ A -eq 6 ] then echo "June" elif [ A -eq 7 ] then echo "July" elif [ A -eq 8 ] then echo "August" elif [ A -eq 9 ] then echo "September" elif [ A -eq 10 ] then echo "Octuber" elif [ A -eq 11 ] then elif [ A -eq 12 ] then echo "December" elif ! [[ "$A" =~ ^[0-9]+$ ]] then echo "No month number given" else echo "Invalid month number given" fi
