Ah, apologies ( that's what I get for trying to send emails during bedtime š ) I have been bitten in the past by arg differences between different Unix flavors. I have tried the following on Mac OS 12.something with just the BaseX jar download. let $ps := proc:execute('ps', ('-o', 'pid,%cpu,command')) return $ps <result> <output> PID %CPU COMMAND 82437 0.0 -bash 82462 16.7 /usr/bin/java -jar BaseX107.jar </output> <code>0</code> </result> This is a borrowed Mac - I didn't install anything. Does your Mac not have a ps; e.g. `which ps`? This one returns `/bin/ps`. Sorry for the noise. Best, Bridger On Thu, Oct 19, 2023, 8:00āÆPM Bridger Dyson-Smith <bdysonsmith@gmail.com> wrote:
Hi Eliot - hope you're well!
Quickly off the cuff, the `ps` command on MacOS is a BSD-flavo(u)r, if I'm remembering correctly (it's been a while...).
I don't have a Mac handy right now, but check this `ps` man page - https://ss64.com/osx/ps.html - your args may need to be adjusted.
Hope that's helpful. Best, Bridger

In the context of a 10.6 server running as a web app, Iām trying to implement a function that uses the process module to run commands to get information about the running BaseX servers, in particular, the PID and port each server is on. I start a number of āworkerā BaseXHTTP instances to handle long-running processes.
On Linux this code works:
let $cmdResult := proc:execute(āpsā, ('-o', 'pid,%cpu,command'))
From which I can parse out the PID and port for BaseX processes:
let $lines as xs:string* := ($cmdResult/output/text() => tokenize(' '))
return
map{
'data' :
let $servers as map(*) := map:merge(
for $line at $p in $lines[contains(., 'BaseXHTTP')]
let $pid as xs:string := tokenize($line, '\s+')[1]
let $port as xs:string := tokenize(substring-after($line, ' -p'),'\s+')[1]
return map{ $port :
map{
'port' : $port,
'pid' : $pid
}
}
)
return $servers
}
However, on macOS thereās not an exact equivalent of the linux version of ps, but there is the āpgrepā command, which, from the command line, lets me get the data I need:
pgrep -lf basex
However, when I try to run this from within BaseX, I get āsysmon request failed with error: sysmond service not found pgrep: Cannot get process listā
I assume this is a function of how the HTTP servers are running on macOS. Iām starting them like so:
"${basexBinDir}/basexhttp" ${debugFlag} -S -p${clientPort} -h${httpPort} -s${stopPort} &
So as a service
Any ideas how I might make this work on mapOS?
Thanks,
Eliot
