In linux/unix, svn automatically updates post-commit hook failed (exit code 255)

Solution to automatic svn update errors in linux/unix:

Post-commit hook failed (exit code 255) with no output.

In linux/unix, after svn is submitted, it is automatically updated to the test server. You can add a hook to/usr/svn/mulu/hooks/post-commit without a suffix.

Set the permission to executable

Chmod 777/usr/svn/baoming/hooks/post-commit
 
#! /Bin/sh
WEB = "/usr/home/mulu"
SVN = "/usr/local/bin/svn"
$ SVN update $ WEB-username ppkj.net-password ppkj.net | exit 1
Exit 0

Exit cannot be missing; otherwise, an error is reported.
