Bash ignoring error for a particular command

Bash Ignoring Error for a Particular Command: A Life Saver! 💥

Are you tired of your Bash script halting at every little error? 😩 We feel you! Thankfully, there's a nifty solution that can save you heaps of time and frustration. In this blog post, we'll tackle the common problem of ignoring errors for a specific command in a Bash script and show you some easy solutions. So, let's dive right in! 🏊‍♂️

The Dilemma: Stumbling Blocks Along the Way

So, imagine you have a Bash script with around 100 lines of code, and you've set the following options at the start:

set -o pipefail
set -e

These options are awesome for stopping the script execution on any error, ensuring early detection and preventing further issues. However, there's just one little hiccup: you have a specific command in your script for which you want to ignore any potential errors. 🚀

The Solution: Bypassing the Error Barrier 🛡️

No worries, dear script-warrior! We've got a few handy solutions up our sleeves that will help you bypass the error barrier for that pesky command. Let's explore them one by one:

Solution 1: Leveraging Subshells 🌐

One elegant way to ignore errors for a particular command is to run it inside a subshell. By doing so, you can suppress the error and carry on with the script execution without a hitch. Simply enclose the command in parentheses ( ) and add the || true flag at the end. For example:

( your_command_here ) || true

🧙‍♂️ Pro tip: Replace your_command_here with your actual command, but keep the structure intact!

Solution 2: Tweaking the Exit Status 📈

Another approach is to modify the exit status of the specific command. By doing this, you can fool Bash into thinking that the command executed successfully, even if it actually failed. Here's how you do it:

your_command_here
exitcode=$?
if [ $exitcode -ne 0 ]; then
  # Error handling goes here
  # Or just ignore the error altogether!
fi

🤓 Note: Replace your_command_here with your actual command, and customize the error handling based on your needs.

Solution 3: Embracing Error Suppression ⛔️

If you simply want to silence the errors for the particular command without any further action, redirecting the command's standard error (stderr) to the null device (/dev/null) is an excellent option. Here's how you can do it:

your_command_here 2>/dev/null

🙌 Keep in mind: Replace your_command_here with the command you want to keep quiet.
