Log output of bash script when part is run as different user

+1 vote
456 views

I have got a bash script that has two parts.
1. runs a script as a different user (using su -c )
2. when that part finishes, the script does a copy of the files created to another directory
I want to log the output of the entire script into one file. i.e.: internal script>external script> logfile
Whats the best way to do this?

Why do you think you need to care about the internal called one? you call whatever and say "redirect my output", that belongs to *anything* called by this script with the only exception of stderr

 command 2>> logfile.txt >> logfile.txt

Have the following in xfce autostart:

#!/bin/bash
# Disable screensaver and dpms emergy star.
export DISPLAY :0.0 
xset s off && 
xset -dpms 

on running:

./xset
./xset: line 4: export: `:0.0': not a valid identifier

It appears to be the correct display going by:

echo $DISPLAY
:0.0

I am trying to understand how to use named pipes in python to launch external processes (in a Linux environment).

As an example I am trying to "imitate" the behaviour of the following sets of commands is bash:

> mkfifo named_pipe
> ls -lah > named_pipe &
> cat < named_pipe

In Python I have tried the following commands:

import os
import subprocess as sp

os.mkfifo("named_pipe",0777) #equivalent to mkfifo in bash..
fw = open("named_pipe",'w')
#at this point the system hangs...

My idea it was to use subprocess.Popen and redirect stdout to fw... next open named_pipe for reading and giving it as input to cat (still using Popen).

I know it is a simple (and rather stupid) example, but I can't manage to make it work..

How would you implement such simple scenario?

I have a script-service running on a remote server, listening on a specific port. What i need here is to make this also maintain a log file of ALL incoming connections.

Could someone suggest to me a simple codefunction example to implement that on my main running service?
