TUPTIME(1)

NAME
tuptime - Reports the system’s historical and statistical uptime, preserved across reboots. Total uptime.

SYNOPSIS
tuptime [-h] [-A STARTUP] [-b] [-c] [-d DATETIME_FMT] [-e DECIMALS] [-E STARTUP] [-f FILE] [-g] [-i] [-k] [-l] [-n] [-o TYPE] [-p] [-q] [-r] [-s] [-S STARTUP] [-t] [--tat TIMESTAMP] [--tsince TIMESTAMP] [--tuntil TIMESTAMP] [-U STARTUP] [-v] [-V]

DESCRIPTION
Tuptime reports the system’s historical and statistical uptime, preserved across reboots. Indeed, it can:
    - Count system startups
    - Register first boot time (a.k.a. installation time)
    - Count nicely and accidentally shutdowns
    - Uptime and downtime percentage since first boot time
    - Accumulated system uptime (running and sleeping), downtime and total
    - Register used kernels and boot IDs
    - Report current uptime
    - Print formatted table or list with the system history
    - Narrow reports since, until or at a given startup or timestamp
    - Output in csv format

OPTIONS

  ARGUMENTS
-h | --help | Show this help message and exit
-A | --at STARTUP | Limit to this startup number
-b | --bootid | Show boot identifier
-c | --csv | Output in csv format
-d | --date DATETIME_FMT | Datetime/timestamp format output
-e | --dec DECIMALS | Number of decimals in percentages
-E | --exclude STARTUP | Startup numbers to exclude
-f | --file FILE | Database file (file path)
-g | --graceful | Register a graceful shutdown
-i | --invert | Startup number in reverse count | swich between longest/shortest on default output
-k | --kernel | Show kernel version
-l | --list | Enumerate system life as list
-n | --noup | Avoid update values into DB
-o | --order TYPE | Order enumerate by [u|r|s|e|d|k] (u = uptime | r = runtime | s = sleep time | e = end status | d = downtime | k = kernel)
-p | --power | Show power states run + sleep
-q | --quiet | Update values into DB without output
-r | --reverse | Reverse order in listings
-s | --seconds | Output time in seconds and epoch
-S | --since STARTUP | Limit from this startup number
-t | --table | Enumerate system life as table
--tat TIMESTAMP | Report system status at specific timestamp
--tsince TIMESTAMP | Limit from this epoch timestamp
--tuntil TIMESTAMP | Limit until this epoch timestamp
-U | --until STARTUP | Limit up until this startup number
-v | --verbose | Verbose output
-V | --version | Show version

  ENVIRONMENT
TUPTIME_DBF
    Set an alternative database file path. The argument -f, --filedb takes precedence over this.

DEFAULT OUTPUT
System startups:
    Total number of system startups from since first timestamp available.

System shutdowns:
    Total number of shutdowns done correctly or incorrectly.

System life:
    Time counter since first startup timestamp available.

System uptime:
System downtime:
    Percentage of time and time counter.

Longest uptime:
Longest downtime:
    Time counter and date with the complete longest uptime/downtime register.

Average uptime:
Average downtime:
    Average time counter.

Current uptime:
    Actual time counter and datetime since registered boot timestamp.

EXAMPLES

tuptime
    Default output.

tuptime -t
    Enumerate system life as table.

tuptime -l
    Enumerate system life as list.

tuptime -k
    Add kernel information to the output.

tuptime --csv
    Report in csv format.

tuptime -s
    Change default human readable datetime/timestamp style and print times in seconds and datetimes in epoch.

tuptime -d '%H:%M:%S %m-%d-%Y'
    Change the datetime/timestamp format. By default the output use the configured system locales.

tuptime --tsince -31557600
    Report since one year ago.
