Parsing a control file loop
Hi,

Let's say I have a control file like this:

Code:
RHEL apple "echo apple"
RHEL bravo "ls -l bravo*"
RHEL church "chmod church.txt"

SUSE drive "chown user1 drive.txt"
SUSE eagle "echo "eagle flies""
SUSE feather "ls -l feather*"

HP-UX google "sed 's/^Google.*$/&\
ACTION: go to www.google.com/' google.txt"
HP-UX heartache "ls -l heartache.txt* | awk '{ print $9 }'"

...and so on.

In my main script, after I get the operating system of the machine I'm executing the script on and assigning it to variable $OPER_SYS, the script will read this control file. For every line with the value of $OPER_SYS, I want the command on the last column be executed.

Please take note of the carriage return on the first HP-UX line. It's intended, because I want the sed command to find the line starting with Google and add a new line after that with the text on the right hand side... and \n doesn't work in HP-UX sed for some reason (if you guys know a way to simplify that, please let me know).

Obviously, the script I'm creating will be executed on several servers with different platforms i.e. RHEL, SUSE, HP-UX, Solaris so I want the code to be executable on all of them (I'm having difficulties with HP-UX obviously).

Thanks in advance.

heimdal_debug

heimdal_debug(5)					      BSD File Formats Manual						  heimdal_debug(5)

NAME

     heimdal_debug -- how to turn on/off debugging for Kerberos tools

DESCRIPTION

     The heimdal_debug kerberos frameworks have several knobs for controlling logging.	The different framework knobs are:

     libkrb
	  The Kerberos library, some gss-api Kerberos output ends up here too

     kcm  the kcm library (credentials cache, ntlm client)

     kdc  the kerberos KDC output

     digest-service
	  the digest service (ntlm server)

CONFIGURATION FILE

	  [logging]
		  <subsystem> = 0-/SYSLOG:
     and watch syslog for logging information.

APPLE MAC OS X

     First turn up syslog debugging
	   sudo syslog -c 0 -d
     then you can see the syslog output in Console.app or by running
	   syslog -w -k org.h5l.asl
     To enable more extensive debugging logging for each subsystem, use the following commands:

	   Kerberos Library
		sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add krb5 '0-/ASL:'

	   digest-server
		sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add digest-service '0-/ASL:'

	   kcm	sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add kcm '0-/ASL:'

	   kdc	sudo defaults write /Library/Preferences/com.apple.Kerberos logging -dict-add kdc '0-/ASL:'

	   MIT Kerberos Shim
		defaults write com.apple.MITKerberosShim EnableDebugging -bool true

	   GSS-API framework logging
		sudo defaults write /Library/Preferences/com.apple.GSS DebugLevel -int 10

Other options on Mac OS X
	  Make the admin API pretend to the server even on client
	       sudo defaults write /Library/Preferences/com.apple.Kerberos ForceHeimODServerMode -bool true
