When the last command lists the entries, what is the default format at the duration?For example: if I have an entry with a duration such as (03:43) does that mean that the user was logged on for 3 hours and 43 minutes?
And if there's an entry with a duration such as (3+02:56) does that mean that the user was logged on for 3 days 2 hours and 56 minutes?

Yeah, for every OS I've used, duration: (days+hours:minutes)

I am looking for a command in bash to change the last modified and created timestamp to be changed to present time.
How do I do it using shell command/script?
Thanks!
touch will update the access and modification times (or only one of the two with -a or -m respectively).

I have a cronjob set to run as
3 6 10 * 1-6 wget'http://...'
How will this execute ? I intend to run it at 6:03 AM on the 10th Of Every Month expect on Sundays.
I am confused as it ran on Saturday, even when the date was not 10th.
Please advise if there is an error with my command or could it be something else ?
The way you have this setup, your command will execute EITHER when the day of the week is 1-6 OR when the day of month is 10.
