How to write a bash script to iterate through files in a specific directory?

Question

bash

You need to create a bash script that creates a directory and copies there
files whose names begin with the letter A (if the directory is not set, it searches in the home
directory)
It is not possible to name this function of setting the search directory through arguments, the code for file in $2 does not work

Answer 1

You need to create a bash script that creates a directory and copies there files whose names begin with the letter A

To do this, you do not need to iterate over the file names, for this you need to use globbing (cp A* "$2") or, if there are too many files, find + xargs.
for ... inonly works with strings: tryfor file in `ls $2`
