Copy/paste files from one directory to another

can you please tell me what is wrong with my simple code? (Mac Bash)

I am trying to copy all files that are called vol_0000.nii from one directory to another. I replaced the variable file name with '*'. All files (vol_0000.nii) have the same name but they are in different folders (Indicated by '*'). Im not sure whether when they are being copied they are replacing each other since they have the same name of the cp creates, for example, vol_00001.nii, vol_00002.nii and so on..?

cp /Users/dave/biomkr/dat/*/rs/orig/vol_0000.nii /Users/dave/Documents/MIT_Har_stu/rsfmri

Something like this should do the job, using a similar numbering behaviour to that which you mentioned in your question.

#!/bin/bash
i=0
for src in /Users/dave/biomkr/dat/*/rs/orig/vol_0000.nii
do
    dest=$(basename "$src")
    dest=${dest/.nii/_$i.nii}
    cp "$src" "/Users/dave/Documents/MIT_Har_stu/rsfmri/$dest"
    let i++
done

Another option is to create a subdirectory, based on the directory name substituted for * in the original glob, which we can get with a little string replacement.

#!/bin/bash
for src in /Users/dave/biomkr/dat/*/rs/orig/vol_0000.nii
do
    srcdir=${src#/Users/dave/biomkr/dat/}
    srcdir=${srcdir%/rs/orig/vol_0000.nii}
    srcdir="/Users/dave/Documents/MIT_Har_stu/rsfmri/$srcdir/"
    mkdir -p "$srcdir"
    cp "$src" "$srcdir"
done
