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

I guess your vi will have made the entire file DOS-style and so there will be another carriage return at the end of the echo statement

Try dos2unix or using an editor that allows you to change the line-ending style or

sed -i "s/$( printf '\015' )//g" yourscript

Answer 2

try to remove the redundant double quote in your first variable assignment.

$ days=$(date +%Y%m%d_%H%M)
$ echo $days #see what output will get?
$ echo "SKIP" > ${days}_EMERGENCY.txt

Answer 3

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
