Concat Variable (date) and String in shell unix - bash

Question

I\'m trying to concat a var (date) and string to have a file with current date name.

My code.

days=\"$(date +\"%Y%m%d_%H%M\")\"
echo \"SKIP\" > ${         


        

Answer 1

It works on my system (OS X) even with double quotes everywhere. For variation I used:

$> days="$(date +'%Y%m%d_%H%M')"
$> echo $days
20160601_1051
$> echo "SKIP" > ${days}_EMERGENCY.txt
$> ll ${days}_EMERGENCY.txt
