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.

apache(1M)                                                System Administration Commands                                                apache(1M)

NAME

       apache - Apache hypertext transfer protocol server overview

DESCRIPTION

        apache  consists  of a main server daemon, loadable server modules, some additional support utilities, configuration files, and documenta-
       tion.

FILES

       The apache HTTPD server is integrated with Solaris.

       The following files specify the installation locations for apache:

       /etc/apache             Contains server configuration files.

                               A newly-installed server must be manually configured before use. Typically this involves copying httpd.conf-example
                               to the httpd.conf file and making local configuration adjustments.

       /usr/apache/bin         Contains the httpd executable as well as other utility programs.

       /usr/apache/htdocs      Contains  the  Apache  manual  in HTML format. This documentation is accessible by way of a link on the server test
                               page that gets installed upon fresh installation.

       /usr/apache/include     Contains the Apache header files, which are needed for building various optional server extensions with apxs(8)

       /usr/apache/jserv       Contains documention for the mod_jserv java servlet module. Documention can be read with a web  browser  using  the
                               url:

                               file:/usr/apache/jserv/docs/index.html

       /usr/apache/libexec     Contains loadable modules (DSOs) supplied with the server. Any modules which are added using apxs(8)are also copied
                               into this directory.

       /usr/apache/man         Contains man pages for the server, utility programs, and mod_perl.

                               Add this directory to your MANPATH to read the Apache man pages. See NOTES.

       /usr/apache/perl5       Contains the modules and library files used by the mod_perl extension to Apache.

       /var/apache/cgi-bin     Default location for the CGI scripts.

                               This can be changed by altering the httpd.conf file and restarting the server.

       /var/apache/htdocs      Default document root.

                               This can be changed by altering the httpd.conf file and restarting the server.

       /var/apache/icons       Icons used by the server.

                               This normally shouldn't need to be changed.

       /var/apache/logs        Contains server log files.

                               The formats, names, and locations of the files in this directory can be altered by various configuration directives
                               in the httpd.conf file.

       /var/apache/proxy       Directory used to cache pages if the caching feature of mod_proxy is enabled in the httpd.conf file.

                               The location of the cache can also be changed by changing the proxy configuration in the httpd.conf file.

NOTES

       In addition to the documentation and man pages included with Solaris, more information is available at http://www.apache.org

       The  Apache  man pages are provided with the programming modules. To view the manual pages for the Apache modules with the man command, add
       /usr/apache/man to the MANPATH environment  variable. See man(1) for  more information. Running catman(1M) on the Apache  manual  pages  is
       not supported.
