helloo All,

i want a batch script to check for a file in a folder,
if the file dosent exist in the folder i want to exit with success
condition, if the file exist in the folder i want to move it to backup
folder and and exit with failure condition.

i have tried with below code but i dont know how to exit. but this
dosent convince me.

if exist "c:\test\file.ext" echo failure
move/y "C:\test\file.ext" "C:\quality\"
if not exist "c:\test\file.ext" echo success



your earliest responce would be appriciated.

Thanks

Raj

I believe you want this ...

if exist "c:\test\file.ext" echo failure
move/y "C:\test\file.ext" "C:\quality\"
goto :EOF
if not exist "c:\test\file.ext" echo success

hi Tom,
thanks for ur reply. how do u see the below code. will
this work if implement .

if not exist "%APP_HOME%\FOREIGN\logs\dforeign.rej" echo success
GOTO :EOF
else
echo failure

MOVE/y "%APP_HOME%\FOREIGN\logs\dforeign.rej"
"%APP_HOME%\FOREIGN\backup\dforeign_%ydt%.rej" >>
%APP_HOME%\FOREIGN\logs\dforeign_reject.log 2>>&1

if %errorlevel% NEQ 0 GOTO ERROR

:ERROR


awaiting ur response.

Thanks

No. There is no Else clause in batch programming. Also, your error
handling accomplishes nothing. I would do something like this.

Try something like this ...

if exist "%APP_HOME%\FOREIGN\logs\dforeign.rej" goto :Else
echo success
GOTO :EOF
:Else
:: This is reached on failure, only
echo failure

(MOVE/y "%APP_HOME%\FOREIGN\logs\dforeign.rej"
"%APP_HOME%\FOREIGN\backup\dforeign_%ydt%.rej" >>
"%APP_HOME%\FOREIGN\logs\dforeign_reject.log" 2>>&1 )

if %errorlevel% EQ 0 GOTO :EOF
echo Undetermined error in MOVE statement

How about you try testing it on your own to find out. Setup a test
environment with test directories and files. You will be surprised what you
can find on your own....

Tom might want to type in "if /?" in a command prompt. Take a look...

Performs conditional processing in batch programs.

IF [NOT] ERRORLEVEL number command
IF [NOT] string1==string2 command
IF [NOT] EXIST filename command

NOT Specifies that Windows XP should carry out
the command only if the condition is false.

ERRORLEVEL number Specifies a true condition if the last program run
returned an exit code equal to or greater than the number
specified.

string1==string2 Specifies a true condition if the specified text strings
match.

EXIST filename Specifies a true condition if the specified filename
exists.

command Specifies the command to carry out if the condition is
met. Command can be followed by ELSE command which
will execute the command after the ELSE keyword if the
specified condition is FALSE

The ELSE clause must occur on the same line as the command after the IF. For
example:

IF EXIST filename. (
del filename.
) ELSE (
echo filename. missing.
)

The following would NOT work because the del command needs to be terminated
by a newline:

IF EXIST filename. del filename. ELSE echo filename. missing

Nor would the following work, since the ELSE command must be on the same line
as the end of the IF command:

IF EXIST filename. del filename.
ELSE echo filename. missing

The following would work if you want it all on one line:

IF EXIST filename. (del filename.) ELSE echo filename. missing

If Command Extensions are enabled IF changes as follows:

IF [/I] string1 compare-op string2 command
IF CMDEXTVERSION number command
IF DEFINED variable command

where compare-op may be one of:

EQU - equal
NEQ - not equal
LSS - less than
LEQ - less than or equal
GTR - greater than
GEQ - greater than or equal

and the /I switch, if specified, says to do case insensitive string
compares. The /I switch can also be used on the string1==string2 form
of IF. These comparisons are generic, in that if both string1 and
string2 are both comprised of all numeric digits, then the strings are
converted to numbers and a numeric comparison is performed.

The CMDEXTVERSION conditional works just like ERRORLEVEL, except it is
comparing against an internal version number associated with the Command
Extensions. The first version is 1. It will be incremented by one when
significant enhancements are added to the Command Extensions.
CMDEXTVERSION conditional is never true when Command Extensions are
disabled.

The DEFINED conditional works just like EXISTS except it takes an
environment variable name and returns true if the environment variable
is defined.

%ERRORLEVEL% will expand into a string representation of
the current value of ERRORLEVEL, provided that there is not already
an environment variable with the name ERRORLEVEL, in which case you
will get its value instead. After running a program, the following
illustrates ERRORLEVEL use:

goto answer%ERRORLEVEL%
:answer0
echo Program had return code 0
:answer1
echo Program had return code 1

You can also using the numerical comparisons above:

IF %ERRORLEVEL% LEQ 1 goto okay

%CMDCMDLINE% will expand into the original command line passed to
CMD.EXE prior to any processing by CMD.EXE, provided that there is not
already an environment variable with the name CMDCMDLINE, in which case
you will get its value instead.

%CMDEXTVERSION% will expand into a string representation of the
current value of CMDEXTVERSION, provided that there is not already
an environment variable with the name CMDEXTVERSION, in which case you
will get its value instead.
