I am sorry about that. I made the mistake of copying the code from post #10 that you said you were using:
Code:
13 16 * * * cd /var/log/apache && ln -s $(ls -r *error_log.* | head -1) error_log
14 16 * * * unlink /var/log/apache/error_log

which used that same construct. But, with a pure Bourne shell from the 1980s being used by cron on Solaris 10, see what happens if you try:
Code:
13 16 * * * cd /var/log/apache && rm -f error_log && ln -s `ls -r *error_log.* | head -1` error_log

Note that this assumes that your error log file names do not contain any IFS characters (usually <space>, <tab>, and <newline>). If they could contain IFS characters you'll need to add double-quotes immediately before the opening back-quote and immediately after the closing back-quote.
