Question

give me the 3 differences each between bash and 5 other shells included csh, ksh as well

Answer 1

Differences between:

Bash and CSH:

1. The csh C shell was developed by Bill Joy and the bash was developed by Brian Fox.

2. The csh is C shell and the bash is Bourne Again shell.

3. The C shell and BASH are both associated with Unix and Linux shells. The bash is the most commonly used processor. The CSH has its own features, the BASH has incorporated many features of other shells like csh, ksh, etc. with its own inbuilt features which makes it flexible and efficient with more features.

Bash and KSH:

1. KSH aka Korn Shell was developed much earlier than that of Bash.

2. The ksh has inbuilt associative arrays, it also handles loop syntax better than bash. The ksh command print is better than bash echo command.

3. Bash has a support of more extensions than that of ksh.

Bash and ZSH:

1. The zsh has much more advanced tab completion features than that of bash; it is said that it also completes filenames and command parameters.

2. In zsh we can say that the look, feel and functionality is considerably more configurable than Bash.

3. Bash does not support an inline wildcard function where as zsh supports that.

Bash and DASH:

1. The Dash is a shell which has a poor use when used as an interactive log-in shell. In spite of that, it is faster in executing POSIX scripts than Bash.

2. The Bash has much more features as compared to dash and is mainly preferred when used interactively.

3. Dash is about 100K whereas Bash is about 900K.

Bash and ASH:

1. The ash is basically a POSIX shell and it offers no additional functionality.

2. The ash does not support [[ ]] with pattern matching which is basically done by Bash.

3. The ash is very much limited. Still, it is considered to be the best for what it is: Its source code is smaller than the bash.
