Cross-platform PL for simple programs?

Question

Programming languages

Good afternoon!
Purpose: to write simple applications for Windows and Linux at the level of bash scripts, well, or a little more difficult.
Example: check for the presence of a folder with the name of the current date + time, write a file to it, if there is no folder, write something to the log.
There are many such small tasks.
In my school years, I used C ++ Builder for home, but firstly, it’s like hammering nails with a microscope, and secondly, Builder costs money (piracy can only be used at home, not at work) and does not work in Linux.
Which language to choose?
Or is it still, taking into account the level of tasks, to delve into the study of PowerShell for win and bash / perl / python for linux?
And, if it's not difficult, point to good literature on PL, it is possible in English.

Answer 1

perl or python - they are cross-platform. and python is very simple, I highly recommend it.

Answer 2

I'm afraid to make a mistake, but what about QT?

Answer 3

Would recommend python.
Although I successfully use php for this, because I know it well, unlike python.

Answer 4

for QT, python has bindings

Answer 5

I would also recommend Python, but programming in it for different axes is still different. It is convenient and fun to write under POSIX, all interfaces are standard, but under Windows it is sad.

Answer 6

Python is unequivocal, Ruby is clearly not worth it.

Answer 7

Thanks for the advice. I'm going to start learning python.
