#1 heure du matin le 23 juillet
0 1 23 7 * root lftp ftp://dexxxxxxx:xxxxxxxx@2x3.xxx.xx.xxx -e "get /www/.htaccess -o /volume1/netbackup/ovh; quit"
si tu veux une autre date tu la mets en respectant la syntaxe
minute heure jour mois joursemaine séparés par une tabulation, * sigifiant tous
exemple : tous les jours à 10 h du matin :
0 10 * * * root commande
tous les lundis à midi :
0 12 * * 1 root commande
The time and date fields are:
field allowed values
----- --------------
minute 0-59
hour 0-23
day of month 1-31
month 1-12 (or names, see below)
day of week 0-7 (0 or 7 is Sun, or use names)
A field may be an asterisk (*), which always stands for "first-last".
Ranges of numbers are allowed. Ranges are two numbers separated with a
hyphen. The specified range is inclusive. For example, 8-11 for an
"hours" entry specifies execution at hours 8, 9, 10 and 11.
Lists are allowed. A list is a set of numbers (or ranges) separated by
commas. Examples: "1,2,5,9", "0-4,8-12".
Step values can be used in conjunction with ranges. Following a range
with "<number>" specifies skips of the number's value through the
range. For example, "0-23/2" can be used in the hours field to specify
command execution every other hour (the alternative in the V7 standard
is "0,2,4,6,8,10,12,14,16,18,20,22"). Steps are also permitted after
an asterisk, so if you want to say "every two hours", just use "*/2".
Names can also be used for the "month" and "day of week" fields. Use
the first three letters of the particular day or month (case doesn't
matter). Ranges or lists of names are not allowed.
The "sixth" field (the rest of the line) specifies the command to be
run. The entire command portion of the line, up to a newline or %
character, will be executed by /bin/sh or by the shell specified in the
SHELL variable of the cronfile. Percent-signs (%) in the command,
unless escaped with backslash (\), will be changed into newline charac‐
ters, and all data after the first % will be sent to the command as
standard input.
mais je verrais mieux un mirror, le dimanche à 23 h :
0 23 * * 0 root lftp ftp://dexxxxxxx:xxxxxxxx@2x3.xxx.xx.xxx -e "mirror /www /volume1/netbackup/ovh; quit"
