Actually I want to create an array of dates and compare it to the today date if it match with the current date then execute test.sh file otherwise exit the loop in bash script. I did like this...

#!/bin/bash

cd /home/user1

current_date=$(date +%Y-%m-%d)

array=['2016-03-02','2016-03-010','2016-05-10']

for i in "${array[@]}"
do
if [ $now -eq $i ]; then
        echo "executing your bash script file"
    ./myscript.sh
fi
done

when i execute above script then it gives error like

./sample.sh: line 6: [: 2016-03-02: integer expression expected

Try it this way:

current_date=$(date +%Y-%m-%d)

array=('2016-03-02' '2016-03-010' '2016-05-10')

for i in "${array[@]}" ; do

    if [ "$current_date" == "$i" ]
        then echo "executing your bash script file"
        #./myscript.sh
    fi

done

The mistakes:

  1. don't use square brackets to declare an array in a bash script - these brackets make commands (see 'if'-tests)
  2. array-elements in bash scripts are separated by whitespaces (no commas)
  3. if you want to compare strings, use double-quotes around the variables, which hold these strings
  4. do not use '-eq' as operator here (because it's an arithmetic-operator). Instead use '==' or '!=' (see here too: http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-11.html)

You don't need to pull bash or arrays for that. You can do:

#! /bin/sh -
if grep -qx "$(date +%Y-%m-%d)" << EOF
2016-03-02
2016-03-01
2016-05-10
EOF
then
   test.sh
fi

or:

#! /bin/sh -
dates="2016-03-02 2016-03-01 2016-05-10"
case " $dates " in
  *" $(date +%Y-%m-%d) "*)
     test.sh
esac

Or just:

#! /bin/sh -
case $(date +%Y-%m-%d) in
  2016-03-02|2016-03-01|2016-05-10) test.sh
esac

For searchable arrays, I'd rather use zsh than bash:

#! /bin/zsh -

dates=(2016-03-02 2016-03-01 2016-05-10)
if ((dates[(I)$(date +%Y-%m-%d)])) test.sh
