I've been trying to get a script which will take the output from syslog and
handle it, but I can't get past the hello world stage. I've tried a bourne
shell script and a python script (which is the language I want to write the
end-result in). With the bourne shell script, I get countless error messages
like the following, with decrementing subprocess IDs:
-----------------------------------------------------
Feb 20 21:39:10 systemname syslogd: Logging subprocess 1894 (exec
/hello_log.sh) exited with status 126.
Feb 20 21:39:10 systemname syslogd: exec /hello_log.sh: Broken pipe
-----------------------------------------------------
Here's the bournshell script hello_log.sh:
-----------------------------------------------------
#!/bin/sh
read line
echo "$line" >> /test.out
-----------------------------------------------------
With the Python script, I only get output after I HUP the syslogd process. I
get all the output I should, but I want it processed real-time by a
run-once-and-die script.
Here's a few variations of the python script I've tried:
-----------------------------------------------------
#!/usr/local/bin/python
import sys
test_file = open("/test.out", 'a')
test_file.write(sys.__stdin__.read())
test_file.flush()
test_file.close()
sys.exit()
-----------------------------------------------------
#!/usr/local/bin/python
import sys
test_file = open("/test.out", 'a')
for char in sys.__stdin__.read():
test_file.write(char)
test_file.flush()
test_file.close()
sys.exit()
-----------------------------------------------------
#!/usr/local/bin/python
import sys
test_file = open("/test.out", 'a')
for char in sys.__stdin__.read():
if char=='\012':
test_file.write(char)
test_file.flush()
test_file.close()
sys.exit()
else:
test_file.write(char)
test_file.flush()
test_file.close()
sys.exit()
-----------------------------------------------------
