I Want To Write A BASH Script To Find The Current DAY And Then Greet The User As Below:

Question

For Monday, print Moanday For Friday, print Friyay For other days, print Foobar

input date: Fri July 20 10:02:15 IST 2018

Output: Friyay

See My Code Below:

day = $(date | cut -d' ' -f1)
if ["$day" == "Monday"];
then
    echo Moanday
elif ["$day" == "Friday"];
then
    echo Friyay
else
    echo Foobar
fi

Paste your script with a shebang first at [shellcheck.net](http://www.shellcheck.net/) and try to implement the recommendations made there. — Cyrus, Jul 16 '20 at 16:08

With bash, GNU date and an array:

d=([1]=Moanday Foobar Foobar Foobar Friday Foobar Foobar)
echo "${d[$(date +%u)]}"

#!/bin/bash
 
# From 'man date'
#-----------------------------------------
# %d     day of month (e.g., 01)
# %u     day of week (1..7); 1 is Monday
# %m     month (01..12) 
 #-----------------------------------------

DAY="$(date +%u)"
DATE="$(date +%d)"
MONTH="$(date +%m)"

case $DAY in
  "1")
    echo -e "Moanday"
    ;;
  "2")
    echo -e "Tueasday"
    ;;
  "3")
    echo -e "Wedneasday"
    ;;
  "4")
    echo -e "Thurasday"
    ;;
  "5")
    echo -e "Friday"
    [[ $DATE = "13" ]] && echo "It's friyay the 13th";exit 0
    ;;
  "6")
    echo -e "Saturday"
    ;;
  "7")
    echo -e "Sunday"
    ;;
esac

# Now you can customize this, my example for christmas:
[[ ${MONTH} = "12" && ${DATE} = "24" ]] && echo "It's christmas time" || echo "It's not christmas time :/"

Why use `date|awk '{print $1}'` when you can `date +%A`? – omajid Jul 16 '20 at 16:26 — omajid, Jul 16 '20 at 16:26
Sure, edited the example script, thanks – wuseman Jul 16 '20 at 16:33 — wuseman, Jul 16 '20 at 16:33

I was able to solve the problem with the help of "shellcheck.net" as recommended by Cyrus. See below for the correct answer.

#!/bin/bash
day=$(date | cut -d' ' -f1)
if [ "$day" == "Monday" ];
then
    echo Moanday
elif [ "$day" == "Friday" ];
then
    echo Friyay
else
    echo Foobar
fi

This script will allways give you "Foobar" since your day command will allways be three characters if you will add all week days as you did, I guess I don't understand the point of this script. :) – wuseman Jul 16 '20 at 17:00
