Question

For example, in a batch file, I typed the command below:

xcopy C:\fileA.txt D:\Dir\ /y /d

It will fail absolutely if there was not a file called fileA.txt. But I want to know if it fails, then output some messages to user. How can I do this?

Any help will be grateful, thanks!

Answer 1

Most commands/programs return a 0 on success and some other value, called errorlevel, to signal an error.

You can check for this in you batch for example by

if not errorlevel 0 goto ERR

xcopy errorlevels:

0 – All files were copied without errors

1 – No files were found to copy (invalid source)

2 – XCOPY was terminated by Ctrl-C before copying was complete

4 – An initialization error occurred.

5 – A disk-write error occurred.
