Download Last Time Wey I Go Check

Curious if anyone knows of a way to via script, command line, or JSS to check the last time an application was opened/run. After some digging on the inter-webs, I couldn't find much. Only way I read was through the finder using the "Date Last Opened" category.

In terms of the information the JSS has: it records the name, version, and amount of minutes in the foreground and the number of minutes open for an application for each and every day. I believe this information is available via the API in versions 9.93+. So technically speaking you could parse through that information date by date and look for your specific application you want and grab the date it was last recorded as being open (though how far back you can search depends on your log flushing schedule).

Yes, use mdls for this as mentioned above. Just a few things. First, you don't need to use grep to pull that data. mdls has syntax to pull just that piece of information. Plus, I would pull column 3 & 4 with awk, not just $3, since the time may also be important.

Note what happens to Illustrator. This output remains the same regardless of order in this list of three. If I change the {print} values, I get more or fewer characters for "Illustrator" in the output, but certainly not the date and time stamp anticipated. Is there something weird with Illustrator not allowing this?

@thellum I know this is an old thread, and I'd like to think you figured this out a long time ago. However, the reason you're getting the odd result on Illustrator is because the Adobe seems not to have control of its individual application teams in terms of a consistent application naming convention. Observe:

@andy-granger Thank you very much indeed for pointing out what should certainly have been obvious. I can now run last-run-checks on Adobe to determine usage and possible redistribution based on the results.

Many thanks, indeed.

Note, it will be different on an app to app basis, but I tested:

/Applications/Sketch.app/Contents/MacOS/Sketch -> resulted in the app creation date

/Applications/Sketch.app -> resulted in the actual time the app was opened.

I know this is older but I wanted to share my attempt at complete EA for this.

Also, some system apps in modern (Monterey at least) macOS are not really in /Applications. For example "/System/Applications/TextEdit.app" you can check by dragging an app from finder into a terminal window to see its true path.

Let's say I lock the door at 1:00. An hour later, it's now 2:00. I'm not sure if the door is still locked. Maybe someone used a key to unlock it. Maybe someone picked the lock and broke in illegally. I don't know. So I check the door and see it is still locked. An hour later at 3:00 I check again and it is still locked. At 3:30 someone asks me "Is the door locked?" I can say, "The last time I checked it was locked, but it's been 30 minutes since I last checked, so I can't be sure if it's still locked now.". In fact I would just say "Last time I checked." That would be a literal non-sarcastic use of the phrase.

A sarcastic use would be if someone asked me "Are you male?" I might answer jokingly, "Last time I checked." This implies that I check my gender from time to time, and that the last time I checked I was male, but I concede the possibility that my gender might have changed without my knowledge since the last time I checked. Of course that's ridiculous. What I'm really saying is the opposite: I am absolutely certain of my gender.

In the end, to a native speaker, the phrase means "I am certain this is true, and to emphasize that I am absolutely certain, I am willing to joke that perhaps I am not certain, that perhaps the situation has changed since the last time I checked, even though I truly believe it cannot have changed."

What I'm trying to find out is if there is a way to find the last time this utility ran. Or alternatively, a way to store the time in the program (so as to compare the last stored time against the current time, and then update the "last time" variable to current time).

As I type this it occurs to me that I could write the time to a file (overwriting the single entry as the utility is run) and retrieve the value from the file in the program, although I don't know if this would be the best approach.

On Raspberry Pi OS systemctl status systemd-timesyncd.service will show initial sync and timedatectl timesync-status will show detail.

On my system this shows Poll interval: 34min 8s (min: 32s; max 34min 8s) i.e. 2048 seconds and /var/lib/systemd/timesync/clock will show the time this was done.

I have a missing computer and I'm trying to find out who last authenticated on the network with it. I know I can use "Get-ADComputer -Identity Computer123 -Properties * | FT Name, Lastlogondate" to get the last time it was logged on, but is it possible to query the DC to see who the last person was to logon with that computer?

I've found that NetworkManager does store last connection time, and it is sorted in /var/lib/NetworkManager/timestamps file, in the unix epoch time format (seconds since 1970). Mine looks like this for instance:

The script itself could be started (as a background job (& at the end of the invocation), possibly with a nohup to keep it running if its parent process terminates) when your user logs in by running it from your $HOME/.profile file, starting it with your desktop autostart utility (KDE or Gnome), from a cron job that periodically checks to see if it's not already running, or even from whatever startup system you have (init/systemd/etc., if you know enough to do that.)

I have a full script, offline_alert, which pretty much does the opposite of what you want - alerts me when I go offline - but the code may prove useful. It has a better offline function which attempts to reduce false positives from ping timeouts.

To find out when was the last time you've run an upgrade, you want to look for a line starting with Upgrade: and then lookup up the timestamp in the following line of the file (which starts with End-Date:). The last such match is the last time you've run an upgrade.

which gives me something like Mar 12 which I can then convert into a date. There are a few minor complications about whether the date is this year or last year, and I'd also need to check /var/log/yum.log.1 in case of checking immediately after a logrotate. But that is just scripting details.

Then you could use yum check-update periodically in cron/other on the Dev servers to see if any updates are available. If this command says > 0 number of updates are available, you compare the current date with the timestamp of file you create when you last did a auto yum upgrade.

You can have a list of your most recently modified files with the modified date and time by using the dataview plugin. @EleanorKonik shared in the discord how she displays files modified in the past 24 hours.

I am looking at a a vertica database of about 80 tables, most of which are not used. I want to figure out which ones have not been used in a while so I can rename and delete them. Is there a script I can run to figure out when all tables in the database were last updated?

You can use the PROJECTION_USAGE system table, io_type = 'output'. Review the current effective retention policy for the corresponding Data Collector tables since those tables control the timeframe covered by the system table.

As explained in the answer you linked to, that depends on your settings. In principle, atime will change each time a file is read and in order to run a script, you need to read it. So yes, normally, the atime will change each time the script is executed. This is easily demonstrated by checking the current atime, running the script and then checking it again:

However, if the script resides on a filesystem that is mounted with the noatime or relatime options (or any of the other possible options that can affect how atime is modified), the behavior will be different:

You can check what options your mounted systems are using by running the command mount with no arguments. The tests I show above were run on a filesystem that was mounted using the relatime option. With this option, atime is updated if i) the current atime is older than the current modification or change time or ii) it is hasn't been updated for more than a day.

I was just doing some work in a devops work tenant, that usually has a Hybrid setup created and Azure AD Connect installed and running, and I realized that I needed to check when was the last time that:

My sincere apologies as I was looking at the wrong information. I double checked on my end and verified that the table that we should also be looking at is actually the content table as well.

Because geo-replication is asynchronous, it is possible that data written to the primary region has not yet been written to the secondary region at the time an outage occurs. The Last Sync Time property indicates the most recent time that data from the primary region is guaranteed to have been written to the secondary region. For accounts that have a hierarchical namespace, the same Last Sync Time property also applies to the metadata managed by the hierarchical namespace, including ACLs. All data and metadata written prior to the last sync time is available on the secondary, while data and metadata written after the last sync time may not have been written to the secondary, and may be lost. Use this property in the event of an outage to estimate the amount of data loss you may incur by initiating an account failover. 006ab0faaa
