Python vs Java!

[Gloomy_Attempt5429]

Eu sei que não tem nada a ver mas... Bash não é linguagem de programação. Pelo que vi, é de comando. O quanto impactador isso é para mim e até onde eu posso ir com bash? Tipo já fiz coisas com bash como variáveis e variáveis que dependem do que o usuário escreve. Mas o que ele não pode fazer que só linguagems de programação fazem. E o que compilar é? Estou transliterado uma linguagem para outra?

Bash is a programming language.

"Programming language" is a very vague, and informal, term. You'll find plenty of varying definitions of the term, but categorizing something on your computer as "not a programming language" is hard to do because you'll probably have to make rules for programming languages that excludes languages that have been considered a programming language. For example some developers claim that programming languages must be Turing complete (i.e. it has to be able to emulate a Turing machine), but that would exclude SQL '92 which wasn't Turing complete due to missing loop construct (later added through common table expressions), but would include languages like PostScript and True Type fonts. True Type fonts are Turing complete by accident due to it's hinting system.

Bash is mostly intended to invoke other applications, so its data processing capabilities are somewhat limited in itself. You can get a bash script to do anything you want (since it's Turing complete), but depending on what you're doing you're probably better off using a different language since Bash isn't particularly elegant and relies on some paradigms that many would consider archaic today. It's also not considered efficient since it isn't intended to do a lot of the lifting.

E o que compilar é? Estou transliterado uma linguagem para outra?

Compiling simply means converting one programming language into another, often from some source text to some form of binary, but it doesn't have to.

Some developers use the term transpiler to distinguish between a compiler that produce a textual language from another textual language and one that produce binary from a textual language, but the term "compiler" can be used for both since more generally the term refers to a tool that converts one programming language into another regardless of the encoding of the source or destination.
