ps -eo pid,lstart,cmd

Discover the process start time

That is useful to discover the start time of process older than 1 day. You can also run: ls -ld /proc/PID That's returning the creation date of the proc files from the process. Some users reported that this way might show you a wrong date since any other process like cron, for example, could change this date.
Sample Output
[root@server ~]# ps -ef | grep [2]8144
root     28144     1  0 Jun16 ?        00:00:00 /opt/omni/lbin/bsm -session_key 25 -owner root root server 28142 4294967295 -lang C -read SmOptions_28142_server_615

  • Fully recharge your computer battery and start this script. It will create or clean the file named battery.txt, print a start on it and every minute it will append a time stamp to it. Batteries last few hours, and each hour will have 60 lines of time stamping. Really good for assuring the system was tested in real life with no surprises. The last time stamp inside the battery.txt file is of interest. It is the time the computer went off, as the battery was dead! Turn on your computer after that, on AC power of course, and open battery.txt. Read the first and last time stamps and now you really know if you can trust your computer sensors. If you want a simple line of text inside the battery.txt file, use this: watch -n 60 'date > battery.txt' The time of death will be printed inside Show Sample Output

    echo start > battery.txt; watch -n 60 'date >> battery.txt'

  • Works on real time clock, unix time based, decrementing the actual time from initial time saved in an environment variable exported to child process inside watch Shows elapsed time from start of script in hh:mm:ss format Non afected by system slow down due to the use of date.

    export I=$(date +%s); watch -t -n 1 'T=$(date +%s);E=$(($T-$I));hours=$((E / 3600)) ; seconds=$((E % 3600)) ; minutes=$((seconds / 60)) ; seconds=$((seconds % 60)) ; echo $(printf "%02d:%02d:%02d" $hours $minutes $seconds)'

  • This command will loop until the process no longer exists, calling closemainwindow() this is as if the user clicked the close window x in the upper right hand corner and gives the user an opportunity to save work in many applications like notepad and other things. The $'s are escaped for Cygwin, if you want to run the same command from the RUN box or cmd.exe shell then just unescape the $'s: powershell -Command "while ($true){Try{$process=Get-Process calc -ErrorAction Stop}Catch [Microsoft.PowerShell.Commands.ProcessCommandException]{break;}if ($process) {$whateva=$process.CloseMainWindow()}else {break;}Start-Sleep -m 500}" Show Sample Output

    powershell -Command "while (\$true){Try{\$process=Get-Process firefox -ErrorAction Stop}Catch [Microsoft.PowerShell.Commands.ProcessCommandException]{break;}if (\$process) {\$whateva=\$process.CloseMainWindow()}else {break;}Start-Sleep -m 500}"
