This allows one to use the system as a date calculator. For example, calendar_showdate '+1 month, 1st Friday' shows the date of the first Friday of next month. With the option -r nothing is printed but the value of the date and time in seconds since the epoch is stored in the ...
The time base for the timestamps is 1 microsecond. Depending on the kernel version and configuration, the timestamps may be derived from the real time clock (origin at the Unix Epoch) or the monotonic clock (origin usually at boot time, unaffected by NTP or manual changes to the clock)...

The gmtime builtin consumes a number of seconds since the Unix epoch and outputs a "broken down time" representation of Greenwich Mean Time as an array of numbers representing (in this order): the year, the month (zero-based), the day of the month (one-based), the hour of the day,...
A single target computer Connect to the remote Linux hosts using New-SshSession from the SSH-Sessions module there's a link to above. Here I connect to the computer ubuntuvm. I already had a session to the IP you see in the output from Get-SshSession. ...
add 1970 years to account for the Unix epoch and you get a max year of 2554, which is just a little bit above what's announced but when manipulating such large numbers it may just be a rounding error of my calculator or imprecision caused by my approximation of the number of days in ...
<li><strong>[blank]</strong>The last three fields are used to denote days before the account is made inactive, days since the Epoch when the account expires. The last field is unused.</li> How Do You Change Passwords? Users' passwords can be modified by issuing the "pass...
See Ceph Placement Groups (PGs) per Pool Calculator for details. On the Object Gateway node, create the done file: Syntax # touch /var/lib/ceph/radosgw/<cluster_name>-rgw.`hostname -s`/done Example # touch /var/lib/ceph/radosgw/ceph-rgw.`hostname -s`/don...
Strongpass-gen is another time saving tool, whenever setting a strong password I always found myself just googling 'strong password generator', going to the page, selecting my password requirement settings, and then I would get a password. This lets me get a couple passwords right from CLI ...
