r397: BUG 1199: check logfile before writing debug output

#!/bin/sh 

#!/bin/bash

# This script is an input filter for printcap printing on a unix machine. It

# uses the smbclient program to print the file to the specified smb-based 

	command="translate;$command";

fi

debugfile="/tmp/smb-print.log"

##

## Some security checks on the logfile if we are using it

##

## make the directory containing the logfile is necessary 

## and set the permissions to be rwx for owner only

##

debugfile="/tmp/smb-print/logfile"

logdir=`dirname $debugfile`

if [ ! -d $logdir ]; then 

	mkdir -m 0700 $logdir

fi

##

## check ownership.  If I don't own it refuse to 

## create the logfile

##

if [ ! -O $logdir ]; then

	echo "user running script does not own $logdir. Ignoring any debug options."

	debug=""

fi

##

## We should be safe at this point to create the log file

## without fear of a symlink attack -- move on to more script work.

##

if [ "x$debug" = "x" ] ; then 

		debugfile=/dev/null debugargs=
