How do I get the current date in Unix or Linux shell scripting and store it into a shell variable? How do I print the current date using Unix shell script?

You need to use the following syntax to print current date and time on screen:


date

To store current date and time to a variable, enter:
now=$(date)
OR
now=`date`

To print this date either use printf or echo statement:

echo "$now"
echo "Current date: $now"

OR use printf:

printf "%s\n" "$n"

You can format and display date using the following syntax:

date +'FORMAT'

### mm/dd/yyyy ###
date +'%m/%d/%Y'

## Time in 12 hr format ###
date +'%r'

Sample shell script

#!/bin/bash
now="$(date)"
printf "Current date and time %s\n" "$now"
 
now="$(date +'%d/%m/%Y')"
printf "Current date in dd/mm/yyyy format %s\n" "$now"
 
echo "Starting backup at $now, please wait..."
# command to backup scripts goes here
