Check file and if it doesnt exist , exit script

Hi,

Another problem, here is my code

Code:
#!/bin/sh

dir='/opt/apps/script/CSV'
datadir='/opt/apps/script/data'

while : ; do
ls -1rt $dir/*.csv > /dev/null 2>&1
if [ $? -eq 0 ] ;then
cp $datadir/weekly.txt $dir/weekly.csv
else
exit 0
fi
done

before it executes the while do, I would like it to check for a file named daily.txt in /opt/apps/script/data/

check /opt/apps/script/data/daily.txt first, if it exists, proceed, else exit code.something like this I guess?

Code:
#!/bin/sh

dir='/opt/apps/script/CSV'
datadir='/opt/apps/script/data'

-> Check here first, if found, proceed, else exit

while : ; do
ls -1rt $dir/*.csv > /dev/null 2>&1
if [ $? -eq 0 ] ;then
cp $datadir/weekly.txt $dir/weekly.csv
else
exit 0
fi
done

Thanks buddies.Regards Smilie

cc(1B)						     SunOS/BSD Compatibility Package Commands						    cc(1B)

NAME
cc - C compiler SYNOPSIS
/usr/ucb/cc [options] DESCRIPTION
/usr/ucb/cc is the interface to the BSD Compatibility Package C compiler. It is a script that looks for the link /usr/ccs/bin/ucbcc to the C compiler. The /usr/ccs/bin/ucbcc link is available only with the SPROcc package, whose default location is /opt/SUNWspro. The /usr/ucb/cc interface is identical to /usr/ccs/bin/ucbcc, except that BSD headers are used and BSD libraries are linked before base libraries. The /opt/SUNWspro/man/man1/acc.1 man page is available only with the SPROcc package. OPTIONS
The /usr/ucb/cc interface accepts the same options as /usr/ccs/bin/ucbcc, with the following exceptions: -Idir Search dir for included files whose names do not begin with a slash (/) prior to searching the usual directories. The directories for multiple -I options are searched in the order specified. The preprocessor first searches for #include files in the directory containing sourcefile, and then in directories named with -I options (if any), then /usr/ucbinclude, and finally, in /usr/include. -Ldir Add dir to the list of directories searched for libraries by /usr/ccs/bin/ucbcc. This option is passed to /usr/ccs/bin/ld and /usr/lib. Directories specified with this option are searched before /usr/ucblib and /usr/lib. -Y P, dir Change the default directory used for finding libraries. EXIT STATUS
The following exit values are returned: 0 Successful compilation or link edit. >0 An error occurred. FILES
/usr/ccs/bin/ld link editor /usr/lib/libc C library /usr/ucbinclude BSD Compatibility directory for header files /usr/ucblib BSD Compatibility directory for libraries /usr/ucblib/libucb BSD Compatibility C library /usr/lib/libsocket library containing socket routines /usr/lib/libnsl library containing network functions /usr/lib/libelf library containing routines to process ELF object files /usr/lib/libaio library containing asynchronous I/O routines ATTRIBUTES

ld(1), a.out(4), attributes(5) NOTES
