Bash Scripting - Error Handling

You want a bash script to stop on any error except for a specific command that might fail but should not stop the script. How do you write this script snippet correctly?

#!/bin/bash
set -e
# Your command here
other_command

Which snippet correctly allows your_command to fail without stopping the script?

Ayour_command ; true other_command

Bset +e your_command other_command

Cyour_command || true other_command

Dtrap '' ERR your_command other_command

Step-by-Step Solution

Solution:

Step 1: Understand selective error ignoring
To allow one command to fail without stopping the script under set -e, append || true to that command.
Step 2: Compare other options
your_command ; true other_command: your_command ; true fails because set -e exits after your_command before true. set +e your_command other_command disables set -e but doesn't re-enable it for other_command. trap '' ERR your_command other_command ignores ERR trap but doesn't restore it, affecting other_command.
Final Answer:
your_command || true other_command -> Option C
Quick Check:
Use command || true to ignore errors selectively [OK]

Quick Trick: Add || true after command to ignore its errors [OK]

Common Mistakes:

MISTAKES

Disabling set -e globally instead of locally
Using if without handling exit status properly
Using traps unnecessarily complicates script
