Can I use Python instead of bash?

Is bash a GUI?

Bash comes with many other GUI tools, in addition to “whiptail” such as “dialog” which can be used to make programming and executing tasks within Linux much easier and fun to work with.

Because it is easy to use for beginners (tab completes commands, etc). It has a lot of common Korn shell behavior. Example: export works in both ksh and bash. It also seems to be very actively developed by the GNU software developers and it looks like it’s constantly being improvised.

Why is bash so slow?

Bash scripts will always be slower than compiled code as they need to be interpreted. As you probably know, in order to run your code written in C you first need to compile it. When it comes to Bash scripts, you don’t have to read it, the code is just “read on the fly”. So Bash is slower than C.
