Prompt:
I need a production-ready Linux shell script to perform a silent installation using IBM Installation Manager (imcl).
Requirements:
The installation must use a response file located in the Downloads directory, and the command will be executed from that directory only.
The response file references a remote, password-protected repository (HTTP/HTTPS).
Repository credentials must be handled securely (no hard-coded credentials in the response file).
The remote repository uses an untrusted or self-signed SSL certificate, so the script must extract the certificate and import it into IBM Installation Manager’s embedded JVM truststore before installation.
The script must:
- Validate prerequisites (imcl exists, response file exists).
- Extract the repository certificate using OpenSSL.
- Import the certificate into the IM JVM
cacertstruststore using keytool.- Configure repository authentication using IBM Installation Manager secure storage.
- Run the silent install using
imcl inputwith logging and license acceptance.The solution must follow IBM-supported practices (no SSL verification bypass).
Assume Linux/UNIX, with IBM Installation Manager already installed.
Deliverables:
- A single end-to-end shell script.
- Clear variable placeholders for repository URL, credentials, IM path, and files.
- Minimal assumptions and suitable for automation or CI/CD usage.
