Can I use the C++/Java-style
/* */ syntax to multi-line comments in the crontab file?
The only comment character allowed in a crontab file is
#. So you need to do:
# This is line 1 # This is line 2 0 0 * * * /usr/bin/magiccronjob
Edit: I believe it's man 5 crontab to see the details about crontab syntax.
