Problem Statement

i often use the bash mode to track my commands easier. but the bash mode dont support user aliases. that means i cannot use shorthand commands. 1 example is "git commit", i set it to "gc" and can execute it in normal shell, but claude-code bash mode wont accept "gc", citing "/bin/bash: line 1: sbash: command not found" and i have to type out "git commit".

Proposed Solution

Configure the shell interaction.
