I am fairly new to Unix (Sun OS) scripting with Ksh, and I could use a little help troubleshooting my script. When I run it, I get the error "if unexpected" on the function setYear. If I comment out the setYear function, I get the error "for unexpected" on the function sendEmails. This leads me to believe that the error lies above the two functions, but I cannot find it. I am hoping that one of you might be able to point me in the right direction. Thanks in advance for the help.

# 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"

There is another problem that needs to be addressed now, and that is code like:
for ((y=0; y<=${#fName[*]}; y++))
You don't say which version of Solaris you are using. As of Solaris 9, /bin/ksh is based on ksh88 and it does not support the arithmetic for statement.
You could just change that to a arithmetic while. This means moving the "y=0" to just before the loop and embedding ((y=y+1)) inside the loop. (no y++ either) This is what I would do.
There is a second option. Solaris comes with dtksh which is in /usr/dt/bin/dtksh. You could switch to that. dtksh is based on ksh93 and it has the more advanced arithemetic constructs. It is heavily extended from ksh since you can write x clients in dtksh. This slows it down somewhat.
But you need to do something here. You are trying to run ksh93 code on a ksh88 intrepreter.

Ok, thanks to all of your help, I have solved many of the problems I was having. I have encountered a new problem, however, that needs dealing with. Is it possible to verify the existance of files using a wildcard? For example, if [ -f "access.log${zero}${star}" ] (where zero="0" and star="*")? In this example, I want to find all files that bear the name "access.log0...". The original file, "access.log" needs to be ignored by the script, and only the files with the numeric suffix need to be tar'd and moved. I have attempted to run it with this syntax, and it appears that none of the files are detected. Is this another syntax problem? Thanks for all the help.
