I'm trying to set up a prompt that will allow the time portion of a unix crontab to be entered, but cannot seem to get the pattern match right
Can anybody spot what I'm doing wrong ?
while ($newtime !~ /[0-59\*]\s+[0-23\*]\s+[1-31\*]\s+[1-12\*]\s+[0-6\*
+]/) {
print qq (\n Enter the time: );
$newtime = <STDIN>;
chomp $newtime;
}
Where a unix crontab should match this
minute (0-59),
hour (0-23),
day of the month (1-31),
month of the year (1-12),
day of the week (0-6 with 0=Sunday).
and each position can also be replaced with an asteris (*)
e.g. I should be able to enter
0 10 * * *
But the code above isn't allowing this
