faketime:tldr:54fad
This command uses the faketime
utility to run a command with a specific faked date and time. Let's break it down:
-
faketime
: This is the utility that allows you to fake the system time while executing a command. -
${today 23:30}
: This is a special syntax used to represent the current date and time in the format "YYYY-MM-DD HH:MM".${today}
is a command that retrieves the current date and time, and23:30
sets the time to 11:30 PM. -
${date}
: This is a placeholder representing the command that you want to run with the fake time. It can be replaced with any other command or script you want to execute.
So, when you run the command faketime '${today 23:30}' ${date}
, the faketime
utility will execute the command represented by ${date}
, but the system time will be faked to the date and time specified in ${today 23:30}
.
