I am looking to sens an SMS when a log file gets updated but i only want to send the last line of the log file.

Is there a function similar to the tail command to do this?

There is a Variable function that you can use:

{STRING(LastLine|1
2
3)}

So, basically you use the Read file Task and then you can use whatever Task you use to send SMS and include the output Variable from the previous Task with the Last Line Variable like this:

{STRING(LastLine|{TASK(PrevTask|StdOut)})}

---

{STRING(LastLine|{TASK(PrevTask|StdOut)})}

I get "error in argument"

{TASK(PrevTask|StdOut)} produces the whole output as expected

We just verified and it should work if;

* the Task after read file is the one where you use the Variable
* if the output contains new line characters

Hi,

Henrik may have covered this with you offline, but LastLine is a recent (VisualCron 7.0.0) addition.

Pre VisualCron 7 (We are still 6.2.2 on our Production Servers) an easy way to do this was using a couple of lines in a VisualCron powershell task. This example is 3 lines but just change the Select-Object to -Last 1 if that is what you want.

This example also uses a VisualCron Trigger as the filename.

This can be replaced with a more traditional filename "C:\Temp\Somefile.log" if that is how you roll (using variables if you have set your log file name).

--- snip ---
# Get the Last 3 Lines of the File found by the Trigger
$Tail = Get-Content "{TRIGGER(d9a226ae-0ad2-42fb-b518-1efd5af13bf7|LastTrigger|File.Result.FullPath)}" | Select-Object -Last 3

# Write that Variable to Output for use in later VisualCron tasks
Write-Output $Tail
--- snip ---

Hope this helps . . . . see screen print
