Bash - How to loop through sub directories and copy in a file

bash, copy, unix

Solution

for i in dir1, dir2, dir3, .., dirN
    do
        cp /home/user1068470/fileToCopy.txt $i
    done

Alternatively, you can use the following code.

for i in *
    do                 # Line breaks are important
        if [ -d $i ]   # Spaces are important
            then
                cp fileToCopy.txt $i
        fi
    done

Problem

I'm new to coding in bash. I'm trying to create something which will loop through all subdirectories, and within each one it should copy a file to that directory. So for example, if I have the following directories ``` /dir1/ /dir2/ /dir3/ ... ... /dirX/ ``` And a file `fileToCopy.txt` Then I want to run something which will open every single `/dirX` file and put `fileToCopy.txt` in that directory. Leaving me with: ``` /dir1/fileToCopy.txt /dir2/fileToCopy.txt /dir3/fileToCopy.txt ... ... /dirX/fileToCopy.txt ``` I would like to do this in a loop, as then I am going to try to modify this loop to add some more steps, as ultimately the .txt file is actually a .java file, I am wanting to copy it into each directory, compile it (with the other classes in there), and run it to gather the output. Thanks.
