Can't display the date correctly in a file generated by a cronjob [duplicate]

How can I execute `date` inside of a cron tab job?
5 answers
I'm doing a cronjob task which creates a daily database backup. To desctinct the daily files, I name them as follows: dump- (the current date). The backup operation went well, but the date is not interpreted as it should be (dump-$(date '+%Y-%m-%d')) instead of dump-14-12-2018.
#filename=dump-$(date '+%Y-%m-%d')
#*/3 * * * * cd /bdd-backups/ && mysqldump --all-databases >
$filename.sql -u xxx -pxxx

It's hard to tell what your problem is,
since you show us a file that's 80% commented out,
but it looks like you are treating the crontab file
as if it were a multi-line shell script.
It's not; each line is a self-contained, independent entity.
So you cannot assign a value to a variable on one line
and use it on another line.
Either put everything on one line, or —
and this is probably better in the long run —
put the date, cd and mysqldump commands into a separate script file,
and run the script from crontab.
