Answer / tony
SH refers to Bourne Shell, which is someway the reference Shell to a lot of other Shells, and defintaly to the Bash Shell, which literally is : Bourne Again Shell. By this time and date (2015), Bash is to be preferred over Bourne, and Bourne is supposed to be limited too much ... but, still used a lot. Obviously, in a technical way, there's a lot of interesting commands that work only with Bash, not with Bourne (and presumingly, never the other way round). So, bottom line : Bourne is limited but very compatible, Bash is better but slightly limited. The latter largely depends on environments.
