Why is bash still used?
Well, when writing with bash, you can directly use every possible tool you have on the command line for your script.
With any other language you would first have to execute that command and get some result etc.
As such, bash is still a good tool for writing quick things..
Why is bash so popular?
“Critical Mass” is the main answer, IMO. Bash is not just for command line work, it’s for scripting and there’s a huge, huge number of Bash scripts out there. No matter how much better an alternative is now for interaction, the need to be able to just “plug and play” those scripts outweighs such advantages.
What does $() mean in bash?
“Usage of the $ like $(echo foo) means run whatever is inside the parentheses in a subshell and return that as the value.”…This is confusing, as this command $(echo foo) will try to run what is returned from the parentheses, it will first run echo foo then will try to run foo which gives an error – Accountant م Apr …
Can you run a Python script without python?
Windows does not come with a Python interpreter installed. … The only realistic way to run a script on Windows without installing Python, is to use py2exe to package it into an executable. Py2exe in turn examines your script, and embeds the proper modules and a python interpreter to run it.
Is Bash a programming language?
Bash is a powerful programming language, one perfectly designed for use on the command line and in shell scripts. This three-part series explores using Bash as a command-line interface (CLI) programming language.
Is bash difficult to learn?
Well, with a good understanding of Computer Science, the so-called “practical programming” is not that difficult to learn. … Bash programming is very simple. You should be learning languages like C and so forth; shell programming is rather trivial compared to these.
Can Python replace bash?
Python should not replace all the bash commands. It is as powerful to write Python programs that behave in a UNIX fashion (that is, read in standard input and write to standard output) as it is to write Python replacements for existing shell commands, such as cat and sort.
Should I learn Bash or Python?
The big advantage bash scripts still have is that you can write and run a bash script on any system with no setup or configuration and it might work forever. … If you are writing a script that is more than 100 lines long, you should probably be writing it in Python instead.
Which is faster Bash or Python?
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.
Should I use zsh or bash?
Completion: both shells default to a basic completion mode that mostly completes command and file names, and switch to a fancy mode by including bash_completion on bash or by running compinit in zsh. … Zsh is usually more precise, but sometimes gives up where bash does something that isn’t correct but is sensible.
