1) In most unixes the errors will be in root mail .
2) As suggested above, refer to the script name by absolute path unless the script happens to be in the limited default path available in cron.
3) There may also be need to set PATH in the script or refer to commands by absolute path,
4) You don't need the "sh " in front of the command. cron defaults to "sh".
5) If you want to capture all output from the script you will need to redirect the error channel too.
Suggested outline for the command field in the crontab line:

Like to enquire whether is it possible for me to append another log file(log2.lst) using my below crontab? I will need to have 2 log files generated; one to collect the daily appended output and another log file that contains only the daily output.

cron
CRON(8) System Manager's Manual CRON(8)NAME
cron - daemon to execute scheduled commands (Vixie Cron)
SYNOPSIS
cron
DESCRIPTION
Cron should be started from /etc/rc or /etc/rc.local. It will return immediately, so you don't need to start it with '&'.
Cron searches /var/spool/cron for crontab files which are named after accounts in /etc/passwd; crontabs found are loaded into memory. Cron
also searches for /etc/crontab and the files in the /etc/cron.d/ directory, which are in a different format (see crontab(5)). Cron then
wakes up every minute, examining all stored crontabs, checking each command to see if it should be run in the current minute. When execut-
ing commands, any output is mailed to the owner of the crontab (or to the user named in the MAILTO environment variable in the crontab, if
such exists).
Additionally, cron checks each minute to see if its spool directory's modtime (or the modtime on /etc/crontab) has changed, and if it has,
cron will then examine the modtime on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab
file is modified. Note that the Crontab(1) command updates the modtime of the spool directory whenever it changes a crontab.
