Issue Evaluation

Category: bug | Status: Confirmed

Root Cause: The error bin/runconnect.sh: 37: [[: not found indicates the script is being executed with /bin/sh instead of /bin/bash. The [[ conditional syntax is bash-specific and not available in POSIX sh.

Fix: Ensure the script is executed with bash:

bash bin/connect-standalone.sh

Or add a proper shebang line #!/usr/bin/env bash at the top of the script if missing.

Issue Evaluation

Category: bug | Status: Confirmed

The script bin/runconnect.sh uses [[ (a bash-ism) but is executed with /bin/sh (which on many systems like Ubuntu/Debian is dash, not bash). The [[ construct is not supported in POSIX sh.

Root Cause: Missing #!/bin/bash shebang or script is invoked with sh instead of bash. The [[ conditional on lines 37, 41, 84, 87, 110 requires bash.
Impact: Script fails to start on systems where /bin/sh is not bash.
Severity: Medium — prevents Connect from starting on common Linux distributions.

Fix options:

1. Add #!/bin/bash shebang and ensure the script is invoked directly (not via sh runconnect.sh)
2. Replace [[ with POSIX-compatible [ tests

Category: bug | Status: Confirmed

The error [[: not found indicates bin/runconnect.sh uses bash-specific syntax ([[) but is being executed by sh (dash on Ubuntu/Debian). The script shebang should be #!/usr/bin/env bash or the script should be invoked explicitly with bash.

Root Cause: Missing or incorrect shebang line, or script invoked with sh instead of bash.
Impact: Cannot start connect runtime on systems where /bin/sh is not bash.
Severity: Medium
