Why does my crontab job fail? 0 0 * * * some command > /var/log/mylog.`date +%Y%m%d`

In many versions of crontab, the percent sign (%) is treated specially, and therefore must be escaped with backslashes:

0 0 * * * some_user some_command > /var/log/mylog.$(date "+\%Y\%m\%d")

See your system's manual (crontab(5) or crontab(1)) for details. Note: on systems which split the crontab manual into two parts, you may have to type man 5 crontab or man -s 5 crontab to read the part you need.

In many versions of {{{crontab}}}, the percent sign (%) is treated specially, and therefore must be escaped with backslashes:

{{{
0 0 * * * some_user some_command > /var/log/mylog.$(date "+\%Y\%m\%d")
}}}

See your system's manual ({{{crontab(5)}}} or {{{crontab(1)}}}) for details.  ''Note: on systems which split the {{{crontab}}} manual into two parts, you may have to type {{{man 5 crontab}}} or {{{man -s 5 crontab}}} to read the part you need.''
