Hello world example gives an error for 'sed' and 'tr'

Hi Team :-)

First of all - I like your project very much. Thank you very much for all your work on this project.

Just tried to do the first baby steps on log4sh starting with the famous 'hello world' example according to doc/log4sh.md.

If I use the preconfigured version, I get the following error message in the function _appender_parsePattern():

++ : _appender_parsePattern 3 -ne 3 8
++ _app_pattern='%-4r [%t] %-5p %c %x - %m%n'
++ _app_priority=INFO

These are the version informations: LOG4SH_VERSION='1.5.1pre' Linux: RHEL5 2.6.18-419.el5 Bash-Version: 3.2.25(1)-release

The script looks as follows:

#
# log4sh example: Hello, world
#
myDir=`dirname $0`

# Find and source log4sh.
if [ -r "$myDir/log4sh" ]; then
  log4shDir=$myDir
elif [ -r "./log4sh" ]; then
  log4shDir=.
else
  echo "fatal: could not find log4sh" >&2
  exit 1
fi

. $log4shDir/log4sh

# Say Hello to the world.
logger_info 'Hello, world'

And finally the properties file...:

#
# log4sh example: Hello, world properties file
#

# Set root logger level to INFO and its only appender to A1.
log4sh.rootLogger=INFO, A1

# A1 is set to be a ConsoleAppender.
log4sh.appender.A1=ConsoleAppender

# A1 uses a PatternLayout.
log4sh.appender.A1.layout=PatternLayout
log4sh.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

Maybe I just made a misconfiguration (or it's a RHEL issue). Do you have an idea why this happens?

Kind regards, Bert99Blib
