How to Fix: Batch file, skip a step if an error occurs
Automate file copying with Robocopy and skip steps if errors occur.
📋 Table of Contents
The script provided attempts to automate the copying of files from two external locations using Robocopy. However, if one of the network locations is unavailable, the script fails and produces an error message (error code 53). This issue can be frustrating as it causes the script to hang indefinitely, waiting for the connection to be retried.
To resolve this issue, we need to modify the script to skip the step that involves the unavailable location. We will explore two methods to achieve this: using the IF ERRORLEVEL command and utilizing the PING command to check if the instrument is present.
⚠️ Common Causes
- The error occurs due to the fact that the script uses NET USE to establish a connection with the network location before attempting to copy files using Robocopy. If the connection cannot be established, the script hangs indefinitely.
- An alternative reason for this issue is that the script does not provide a mechanism to check if the instrument is present before attempting to copy files.
🚀 How to Resolve This Issue
Using IF ERRORLEVEL command
- Step 1: Add the following line of code after the NET USE command: IF ERRORLEVEL 53 GOTO skip_step. This will check if an error occurred (error code 53) and skip the subsequent steps if it does.
- Step 2: Modify the script to include a label for the step that should be skipped: GOTO skip_step. This will cause the script to jump to the labeled step if an error occurs.
- Step 3: Add the following line of code after the ROBOCOPY command: GOTO end_script. This will mark the end of the script and prevent it from hanging indefinitely.
Using PING command
- Step 1: Replace the NET USE command with a PING command to check if the instrument is present: PING -n 1 \192.168.10.90 > NUL 2>&1 IF %ERRORLEVEL% NEQ 0 GOTO skip_step.
- Step 2: Add the same label (GOTO skip_step) as in Method 1 to mark the step that should be skipped.
💡 Conclusion
By implementing either of these methods, you can modify the script to skip the step that involves the unavailable location and prevent it from hanging indefinitely. This will ensure that the script continues to run even if one of the network locations is not present.
