To find out the empty files(0 bytes size) in UNIX

I do not see the test command in the IF loop...
so in case I need to check this for two files wat needs to be done ?Is the below code correct ??
------------------------------------------------------------------------
#!/bin/csh
if ($#argv == 1) then
echo "Begin moving files"
mv file1 /file/file1$1
mv file2 /file/file2$1
mv file3 /file/file3$1
echo "Files Moved Successfully"
(if [ -s file1 && -s file2]; then
(uuencode /file/file1$1 file1$1; uuencode /file/file2$1 file2$1) |mailx -s "Report" alias@mymail.com
else
echo "file1$1 is empty" |uuencode /file/file2$1 file2$1 |mailx -s "Report" alias@mymail.com)
else
echo "Enter date suffix for the filename in the format mmmddyy"
endif
#
---------------------------------------------------------------------------------------------

I don't know csh well, but I think you need to do this:
The "test" call builtin the shell.

if ( -s file1 && -s file2 ) then
(uuencode /file/file1$1 file1$1; uuencode /file/file2$1 file2$1) |mailx -s "Report" alias@mymail.com
else if ( ! -s file1 ) then
echo "file1$1 is empty" |uuencode /file/file2$1 file2$1 |mailx -s "Report" alias@mymail.com)
else if ( ! -s file2) then 
echo "file2$1 is empty" |uuencode /file/file2$1 file2$1 |mailx -s "Report" alias@mymail.com)
endif

I am getting an error in this.Code :
--------------------------------------------------------------------------
#!/bin/csh
if ( -s /file/file1 && -s /file/file2 )
then
echo "Both files present"
else
echo "file1 or 2 is empty" |uuencode /file/file2 file2  |mailx -s "Report" alias@mailid.com
endif
-----------------------------------------------------------------------------------------
Error:
if: Badly formed number
-----------------------------------------------------------------------
can you tell me where is the error in this ?

This script is a part of a bigger script so don't want to modify this now.

SYNOPSIS
     /usr/bin/test [condition]

     [ [condition] ]

  sh
     test [condition]

     [ [condition] ]

  csh
     test [condition]

     [ [condition] ]

  ksh
     test [condition]

     [ [condition] ]
----------------------------------------------
can you check this and tell me how the script needs to be modified per this ?

I'm not sure I understood your latest statement. What do you want me to check?
If the csh is the only option, then you should try doing the if calling the binary test with the backquotes. The error you were getting before was caused because the csh's test builtin (that is called when you only start an expression like if and then only put the -s option) doesn't support the size checking option.
In this case your only option is to use the binary itself (or start doing ls and checking the size field with awk and so on, too much trouble for something this simple I think).

I tried to execute the above code.It gives me the error :
******************************************************************************************
#!/bin/csh
if ( `/usr/bin/test -s /file/file1` && `/usr/bin/test -s /file/file2` )
then
echo "Both files present"
else
echo "file1 or 2 is empty" |uuencode /file/file2 file2  |mailx -s "Report" alias@mailid.com
endif
********************************************************************************************8
if: Empty if

Can you let me know what is causing the problem here ?

if ( test -s /file/file1 -a -s /file/file2  )

Are you sure your test binary is located at /usr/bin? Can you execute /usr/bin/test manually? I tested this code before posting, and it worked in my machine.

this script worked after removing the space :
************************************************************************************************
#!/bin/csh
if ( `/usr/bin/test -s /file/file1` && `/usr/bin/test -s /file/file2` )
then
echo "Both files present"
else
echo "file1 or 2 is empty" |uuencode /file/file2 file2  |mailx -s "Report" alias@mailid.com
endif
*****************************************************************************
Can you pls modify the below code also accordingly :

else if ( ! -s file1 ) then
echo "file1$1 is empty" |uuencode /file/file2$1 file2$1 |mailx -s "Report" alias@mymail.com)
*******************************************************************************

The idea in this case would be the same:
You just need to call the "test" binary directly instead of using csh's builtin. Please make sure that the "then" clause is in the same line as the "if" clause. This is the cause for your "empty if" errors.

else if ( ! `/usr/bin/test -s file1` ) then
echo "file1$1 is empty" |uuencode /file/file2$1 file2$1 |mailx -s "Report" alias@mymail.com)
endif

Code:
*****************************************************************************************
#!/bin/csh
if ( `/usr/bin/test -s /file/file1` && `/usr/bin/test -s /file/file2` )
then
echo "Both files present"
else if (!  `/usr/bin/test -s /file/file1`) then
echo "file1 is empty"
endif

Can you pls tell me wat needs to be done ?

Pls ignore that...!!!It is working...
