【CMD｜Shell】/bin/bash

"/bin/bash" refers to the Bash executable located in the/bin directory on Unix-like systems, including macOS and Linux. 

In Unix-like file systems, the/bin directory typically contains essential binary executables (commands) that are required for the system to function, and Bash is one such essential shell program.

So, when you see /bin/bash, it specifies the location of the Bash executable (bash) within the/bin directory. The /bindirectory is short for "binary," and it contains fundamental binary executables used for system bootstrapping and basic operations.
