An interesting problem with cron?

Question

linux

Good day!
I ran into a problem in cron - when specifying a clear task execution time, cron simply reloads the config:

19 13 * * * /usr/sbin/squid3 -k reconfigure 
cron.log : Apr 16 13:19:01 r38p-01-proxyd /usr/sbin/cron[2299]: (root) RELOAD (crontabs/root)

But at the same time, if you specify such an interval:

*/1 * * * * /usr/sbin/squid3 -k reconfigure
cron.log: Apr 16 13:20:01 r38p-01-proxyd /USR/SBIN/CRON[19715]: (root) CMD (/usr/sbin/squid3 -k reconfigure)

then everything works great. What could be the problem?

Answer 1

#minute hour mday month wday who command
*/5 * * * * root /usr/libexec/atrun
Where is the user?

Answer 2

Maybe try putting the command in quotes?

Answer 3

Alternatively, try this.
/usr/sbin/squid3 -k reconfigure >> /dev/null 2>&1

Answer 4

Not

Answer 5

If this is the last line, then you need a CR at the end.
There are problems without it.
