How to automatically run a R file from different directories?-CodePudding

I have a file: /mnt/d/main_folder/sub_folder1/ak33.R.

The ak33.R file is in all the sub folders :
/mnt/d/main_folder/sub_folder2/ak33.R
/mnt/d/main_folder/sub_folder3/ak33.R
/mnt/d/main_folder/sub_folder4/ak33.R
/mnt/d/main_folder/sub_folder5/ak33.R

I wanted to run this ak33.R file from all these sub folders, how do i run using linux bash script using a for loop?

is there a command to read all the sub folders name and run them in for loop ?

Try the following:

for d in /mnt/d/main_folder/sub_folder*/; do
  Rscript "$d"ak33.R
done

If the sub folder number is just one character, you can use the ? meta-character.

for d in /mnt/d/main_folder/sub_folder?/; do
  Rscript "$d"ak33.R
done

I tried the following at my environment:

#!/bin/bash
if [[ ! -d /mnt/d/main_folder ]]
then
    echo "/mnt/d/main_folder not found"
else
    AK33FOUND=0
    for AK33FILES in $(find /mnt/d/main_folder -type f -name ak33.R 2>/dev/null)
    do
        if [[ -f "$AK33FILES" ]]
        then
            AK33FOUND=1
            if [[ -x "$AK33FILES" ]]
            then
                $AK33FILES
            else
                echo "$AK33FILES execute permission denied."
            fi
        fi
    done
    if [[ 0 -eq $AK33FOUND ]]
    then
        echo "No ak33.R files found at /mnt/d/main_folder"
    fi
fi
