Linux distribution maintainers believe Bash is an inferior shell for scripting. It may be a superior shell for interactive use, depending on personal preference.

No one is prevented from using whatever shell they prefer for whatever purpose. For example I prefer to use a smaller, slightly modified scripting shell for interactive use. Some folks prefer to use a large, interactive shell for scripting.

Choice of scripting shell is personal preference. Preferences may differ amongst computer owners. For example, I prefer NetBSD sh. On Linux I use a slightly modified Dash.

As for the preferences of others, I note the default scripting shell on the largest Linux distributions is not Bash. It is of course Dash, which is derived from NetBSD sh, which is derived from the Almquist shell (ash). Indeed, ash is a popular choice for scripting. It is smaller and faster than Bash.

Any recommendation on small shells? ash?
