[BUG]: Sample deployment: sed -i '' substitution command not compatible with Linux and Windows Subsystem Linux

[Ben-Dowling]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

In samples/common.sh, the use of sed -i '' (the macOS syntax for in-place edits) is not compatible with GNU sed on Linux and Windows Subsystem for Linux (WSL). This causes failures when running the substitution commands on those platforms.

As a result, the substitutions in the pipeline configuration files (e.g. dev_substitutions.json) are not applied, causing the sample pipeline to fail.

Expected Behavior

The substitution script works cross-platform (macOS, Linux, WSL).

Steps To Reproduce

1. Clone or fork the repo on a Linux or WSL environment
2. Run the samples/deploy.sh (I used Databricks CLI v0.297.2, on a MinGW terminal on Windows)
3. Check the resultant pipeline config files (e.g. pipeline_configs/dev_substitutions.json), they have not received the correct substitutions.
4. Run a sample pipeline (Lakeflow Framework - Run 1 - Load and Schema Initialization), dependant tasks (e.g. bronze_base_pipeline) fail.
