To exit a script upon encountering an error, you can use the set -e command at the beginning of your shell script. This will cause the script to terminate immediately if any command in the script returns a non-zero exit status.

💡 Example Usage:

  • Set -e at the beginning of your script:

Example Script:

  1. 1. #!/bin/bash
  2. 2. set -e
  3. 3. if jarsigner -verbose -keystore $keyst -keystore $pass $jar_file $kalias; then

    4. Example Script (continued):

    1. 4. echo $jar_file signed successfully
    2. 5. else
    3. 6. echo ERROR: Failed to sign $jar_file. Please recheck the variables

      4. ✨ Wrapping Up

      By using set -e, you can ensure that your script terminates immediately if an error occurs, making it easier to diagnose and fix issues.
