Difference between sh and bash

OP: https://stackoverflow.com/questions/5725296/difference-between-sh-and-bash

sh & bash

sh is a specification, not an implementation.

bash started as an sh-compatible implementation.

Which one to use

For my own scripts, I prefer sh for the following reasons:

• it is standardized
• it is much simpler and easier to learn
• it is portable across POSIX systems — even if they happen not to have bash, they are required to have sh
