How check share UNC

[darioit]

Hello everyone,

I'm looking for a very simple script that check if UNC share as "\\server\abc" is available before copy some file into that.

I got error after copy file, but it would be useful to know before if a share is down or user has no permission to copy file.

Best Regards

Well to see if the share is up and running you could just do an IF EXIST.

Code: Select all

if EXIST "\\Server\Share\Folder" echo exists

Not sure about testing for permissions. I guess I would just try and copy the batch file itself to the share and check the errorlevel.

I check this script

Code: Select all

if EXIST "\\Server\Share\Folder" echo exists

if exist errorlevel=0
if NOT exist errorlevel=0
if NOT authorized errorlevel=0

That's the point !

Note the trailing slash - it defines a folder.

Code: Select all

if EXIST "\\Server\Share\Folder\" (
copy file
) else (
echo unavailable
)

Check it yourself to see what happens if you don't have access.

[Squashman]

if exist errorlevel=0
if NOT exist errorlevel=0
if NOT authorized errorlevel=0

None of those are properly formatted commands.

Foxidrive makes a good point about the trailing slash. That way it matches against a folder or share name and not a file.

It does work. I normally don't post code unless I tested it first.

Code: Select all

H:\>IF EXIST "\\Server\Share\TEMP\" echo the Folder exists
the Folder exists

[darioit]

if exist errorlevel=0
if NOT exist errorlevel=0
if NOT authorized errorlevel=0

None of those are properly formatted commands.

sorry this is not a command but the result of command
This is the right script:

Code: Select all

if exist "\\Server\Share\Folder" echo exists
echo %errorlevel%

in all case tested %errorlevel% is always 0

Of course the ERRORLEVEL will be zero because the IF command completed successfully. It didn't error out.

Code: Select all

H:\> if 1==1 echo equal
equal

H:\>echo %errorlevel%
0

H:\> if 1==0 echo equal

H:\>echo %errorlevel%
0

Either use the IF ELSE code Foxidrive gave you to execute another command when the condition is true or set a flag with another variable.

Code: Select all

if exist "\\Server\Share\Folder" set SHAREFLAG=Y
