Estou bastante novo em Unix (Sun OS) com Ksh scripting, e eu poderia usar um pouco de ajuda para solucionar problemas meu script. Quando eu executá-lo, eu recebo o erro "se inesperado" sobre a função setYear. Se eu comente as setYear funcionar, eu recebo o erro "para o inesperado" sobre a função sendEmails. Isso me leva a crer que o erro se situa acima das duas funções, mas não posso encontrá-lo. Estou esperando que um de vocês pode ser capaz de me aponte na direcção certa. Agradecemos antecipadamente pela ajuda.

# Purpose:   This is a test of the automated monthly eBCCS log file backup.
#            The actual copies of this file are on the following servers:  

dmocnu.on.bell.ca, dmocnt.on.bell.ca, dc1c3m.qc.bell.ca

# The following files need to be backed up each month (usually on the 7th):
# Nohup.out
# PHLog.txt
# PSQTLog.txt
# Response-Log.txt
# Access.log
# Weblogic.log
# ServiceAddressQueryResponseLog.txt

# this sets the email addresses that are sent the temp file containing the command outputs
email_addresses="tina.naugler@cgi.com m.harley@cgi.com pamela.green@cgi.com"

# this puts the instance names in an array
set -A instance
instance[1]="ont0"
