"Syntax error: Unterminated quoted string" only when calling from crontab

Question

Why do I get this error

/bin/sh: 1: Syntax error: Unterminated quoted string

when calling this in /etc/crontab?

19 2 * * *   root    for f in $(cat /home/rubo77/list); do date +"%y-%m-%d %T">"$f".datefile; done

The list only contains paths to existing directories and those are the first lines in my crontab:

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

When I call the for commandline on the console in bash I get no errors

Answer 1

You need to escape the % signs

see this related question: How can I execute `date` inside of a cron tab job?

You can use this to fix it

sed -i 's/%/\\%/g' /etc/crontab
