Antwort Is Bash more powerful than Python? Weitere Antworten – Is Bash better than Python
Performance and execution time: Bash scripts tend to run faster than Python scripts because they do not require an interpreter to execute the code. Bash scripts are directly executed by the shell, which makes them faster than Python scripts that need to be interpreted by a Python interpreter.If you intend to write a script that has to be portable, use Python. If you need libraries to do something sophisticated, use Python. You should choose Bash for scripts that are intended mostly as glue for command line commands on a Unix or Linux system. That's what Bash is designed for.Performance-wise bash outperforms python in the process startup time. This shows a huge difference however bash execution time degrades quickly if it has to do anything sensible since it usually must call external processes. If you care about performance use bash only for: really simple and frequently called scripts.
Is Bash or Python faster : Python is drastically faster on text processing, which is a common operation. If I perform the same search 10000 times on each language, on Bash it takes 1m24s, on Python 636ms. This is because Bash use a sub-process for each operation of the text processing, which is slow to create.
Why do people still use Bash
Every shell has its own scripting language and, since bash is the default shell with Linux, most development and admin teams use the bash scripting language. With these scripts, you can do almost anything. And like Python, they're fairly easy to learn and don't require a compiler to use.
Why Python instead of Bash : However, Python is more flexible than Bash because you can run its scripts on different platforms, such as macOS, Windows, Linux, etc. Python is designed to create a simple-to-read program, while Bash is the command-line interpreter to execute commands automatically.
Bash will still be available, but Apple is signaling that developers should start moving to zsh on macOS Mojave or earlier in anticipation of bash eventually going away in macOS.
Most importantly, programmers who use Bash in Windows can run the same commands and utilities to query, create, edit, run, and delete files and directories.

The current v5 bash is under the GPLv3 license that is poison to companies like Apple, so they cannot give you an up-to-date bash with bug fixes.
Bash scripting is a powerful and versatile tool for automating system administration tasks, managing system resources, and performing other routine tasks in Unix/Linux systems.
Does macOS still use bash : Zsh replaced Bash as macOS's default terminal shell in macOS Catalina. While Zsh is in many ways superior to Bash, thanks to its floating-point support, hash data structures, customization options, etc., there are still use cases where Bash may prove helpful in the macOS terminal.
Why did Apple drop bash : The version of bash shipped with macOS is VERY OLD (v3. 2.57), but that version is still GPLv2 license and Apple is allowed to distribute it. The current v5 bash is under the GPLv3 license that is poison to companies like Apple, so they cannot give you an up-to-date bash with bug fixes.
Should I use zsh or bash on Mac
Zsh replaced Bash as macOS's default terminal shell in macOS Catalina. While Zsh is in many ways superior to Bash, thanks to its floating-point support, hash data structures, customization options, etc., there are still use cases where Bash may prove helpful in the macOS terminal.
Run the following command in both the shell to see the script execution time in each shell. Replace the shell_name with zsh/bash and some long sentences in the above command. The left and right outputs are for zsh and bash respectively. The results in both the above snippets show that zsh is faster than bash.Because of licensing. Newer versions of Bash are released under GPLv3, and there are a lot of problems with that for Apple. Shouldn't be an issue; zsh can act like bash well enough for those who want it. Apple's macOS Catalina 10.15 introduced the new default shell, Zsh, or the Z Shell.
How fast is Python vs Bash : A Python Implementation
And the time is about double the best time we get with bash. It requires writing more code but also this code is super fast and probably more easily modifiable for many.
