Exit Code 1 in Linux: General Termination with Error

Exit Code 1 is a general exit code indicating that the program terminated with an error. Unlike codes 137 or 139, it does not specify a particular type of failure.

Main Causes

• Configuration error
• Missing file or resource
• Exception within the application
• Incorrect launch parameters
• Error in the Bash script

Method 1: Manual Launch for Diagnosis

If the program is launched through a script or Docker, try running it directly:

./app

This may reveal the exact reason for the error.

Method 2: Checking Docker Logs

docker logs container_name

Logs often contain the error stack or a message about incorrect configuration.

Method 3: Checking Exit Code in Bash

After executing the command, check:

echo $?

If the output is 1, it means the program terminated with a general error.

Method 4: Checking Permissions and Paths

Make sure that:

• Files exist
• Paths are specified correctly
• The user has the necessary permissions

Conclusion

Exit Code 1 is a universal indicator of failure. To fix it, one needs to analyze logs, launch parameters, and application configuration.
