The ash shell is the most bash compatible and full featured one.

Note that selecting this option does not switch on any bash
|

|
compatibility code. It merely makes it possible to install
|
||||||
|
/bin/bash (sym)link and run scripts which start with
|
||||||
|
#!/bin/bash line.
|
||||||
|
|
||||||
|
Many systems use it in scripts which use bash-specific features,
|
||||||
|
even simple ones like $RANDOM. Without this option, busybox
|
||||||
|
can't be used for running them because it won't recongnize
|
||||||
|
"bash" as a supported applet name.
