The exit code 2 indicates that the process has completed with an error. Exit codes are used by programs or scripts to indicate the outcome of a task or operation. Each exit code has a specific meaning and is typically documented in the program’s documentation or system standards.
Exit code 2 commonly represents a command or program failure. It is often used to indicate an error that occurred due to incorrect usage, invalid arguments, or insufficient privileges. The exact meaning of exit code 2 may vary depending on the specific program or script being executed.
Here is an example to better understand how exit code 2 can be used:
Let’s consider a script that checks if a file exists and performs some operations on that file. If the file is not found, the script may exit with exit code 2, indicating a file not found error.
#!/bin/bash
if [ -f "myfile.txt" ]; then
echo "File exists"
# Perform operations on the file
else
echo "File not found"
exit 2
fi
In the above example, if the file “myfile.txt” does not exist, the script will output “File not found” and exit with exit code 2. This exit code can then be used by calling programs or scripts to handle the error and perform the appropriate actions.
It’s important to note that the exact meaning of exit codes can vary between different programs and operating systems. Therefore, it’s always a good practice to consult the documentation or resources specific to the program or script you are working with to understand the exact meaning of exit code 2 in that context.
