Linux HS: bash script support?

[desolatax]

Does the linux HS script support running bash scripts? I haven't tried the linux release yet, and haven't seen anything on the boards about it.

Does not seem to work

It does not seem to work. The only way I could try is to create an event to start a program. You can select a program on the local filesystem, but I get this error when running this event.

Error Event system events New Event failed to launch \usr\bin\uptime as the file could not be found.

This is some functionality that I'd find extremely useful. I'm a linux sysadmin at work, so bash/perl + homeseer would be amazing.

perl script on Linux

Following the HS3 documentation, Perl scripts run on Linux (and on Windows too). I have developed several perl scripts working on HS2 but for the moment, I don't find how to run them on HS3 Linux. However, they run on HS3 Windows.
I don't think that other scripting languages (e.g. Linux command in a bash file) run on Linux except if you run them as a executable program.

Linux HS: bash script support?

I just tried to run the restart.sh from an event just like Zigmund explains in post 3. Although the event shows the path with the "/" folder delimiters for Linux, the error seems to suggest that it's using the "\" delimiter for Windows when it tries to run and therefore cannot find the intended file.

Anyone from HST: Is this a known problem; needs a bug to be submitted, or just not supposed to be used the way that we are trying to use it?

Thanks James

fixed: hs3 script to run bash scripts on linux host

I managed to create a small script to run linux (bash) commands for homeseer on linux hosts. here it is:

imports System.Diagnostics

Sub Main(parm as object)
Dim psi As New ProcessStartInfo()

psi.FileName = "/bin/bash"
psi.Arguments = "-c ""uname -a"""
psi.RedirectStandardOutput = True
psi.RedirectStandardError = True
psi.CreateNoWindow = False
psi.WindowStyle = ProcessWindowStyle.Hidden
psi.UseShellExecute = False

Dim process As Process = Process.Start(psi)
Dim processoutput As String = process.StandardOutput.ReadToEnd()

process.WaitForExit()

hs.writelog("Output", processoutput)

End Sub

Interesting stuff Zigmund! I'll give it a try when I have some spare time.

I have an alternate and faster method of executing bash scripts on Linux using HomeSeers speak.sh.

I simply added the code:

# Execute bash command
case $1 in bash*)
command=$(echo "$1" | sed -e 's/\<bash\>//g' | sed -e 's/^ *//')
eval $command
esac

now for any speak event in HomeSeer that starts with the word "bash", that will be executed as a script.

This avoids the delay involved in executing using a vb script as the first time its run after each reboot can result in up to a 6 second delay on my system. Using this method I have seen no visible delay at all even after restart.

Obviously customise for your system as needed.

Figured out how to do it directly using the HomeSeer run a program event option. In Linux one has to choose the "program being run" in this case: /bin/sh THEN append the options of what to do. See screenshot.

Very nice cytec!

Thanks for the info on this guys. I am using HS3 on Ubuntu, migrating from Vera where I used curl to POST to a Raspberry Pi running a relay board and Webiopi. This allows me to setup a low end amp and use the relay board to turn on/off rooms.

I set the executable to /usr/bin/curl and the variable to -X POST http://192.168.1.19:8000/GPIO/2/value/0 if anyone else was trying to do similiar and can't get urlaction to work.

hey.
i am using your script for a long time to be able to run from hstouch bash scripts.
i have a small problem, i would like to pass parameters to the command.

this works
psi.Arguments = "-c ""/scripts/play_80.sh 192.168.1.1"""

this doesn't:
psi.Arguments = "-c ""/scripts/(parm(0).sh (parm(01))"""

i am guessing that it doesn't pass the parameters to the command line.

is there a way to change the line so it will use it?
thanks

[zigmund]

maybe this will work

this will work: passing parm to the bash script command
use a comma to split the parameters. e.g. play80,192.168.1.2

Sub Main(parm as object)
       Dim param1 As String = Split(parm,",")(0).ToString
       Dim param2 As String = Split(parm,",")(1).ToString

....


    Psi.Arguments As String  = "-c " & " ""/scripts/" & param1 & ".sh " & param2 & " "" "
.... 

End Sub

Thanks for your help.
the script looks like this now:

imports System.Diagnostics

Sub Main(parm as object)
Dim psi As New ProcessStartInfo()
Dim param1 As String = Split(parm,",")(0).ToString
Dim param2 As String = Split(parm,",")(1).ToString



psi.FileName = "/bin/bash"
'psi.Arguments = "-c ""/var/local/HomeSeer/scripts/media/70.sh 53"""
Psi.Arguments As String = "-c " & " ""/var/local/HomeSeer/scripts/media/" & param2 & ".sh " & param1 & " "" "

psi.RedirectStandardOutput = True
psi.RedirectStandardError = True
psi.CreateNoWindow = False
psi.WindowStyle = ProcessWindowStyle.Hidden
psi.UseShellExecute = False

Dim process As Process = Process.Start(psi)
Dim processoutput As String = process.StandardOutput.ReadToEnd()

process.WaitForExit()

hs.writelog("Output", processoutput)

End Sub
~




i can verify that parm(0) got the value 80
and parm(01) got the value 53

so the command should have looked like this:
Psi.Arguments As String = "-c " & " ""/var/local/HomeSeer/scripts/media/80.sh 53""" (which works when inserted directly into the command)

but now i get this in the log:

Mar-23 11:08:49 Error Compiling script play_media.vb: 'End Namespace' must be preceded by a matching 'Namespace'.
Mar-23 11:08:49 Error Compiling script play_media.vb: Identifier expected.

Excellent description of how to use shell scripts in Homeseer. Buuut I seem to be doing something wrong..

My configuration looks like what I have added as screenshots, but I can get the command to execute successfully if I run the script by itself, but when run through Homeseer as an event it doesn't work. Or nothing happens would be more correctly. Have I configured it wrong?
