I am trying to move one a bunch of files at once, one directory up.

This is what I tried, but did not work:

mv ./*/__test__/index.js ./*/data.js

.
├── alpha
│ ├── __test__
│ │ └── index.js
│ ├── index.js
│ └── test.js
└── beta
 ├── __test__
 │ └── index.js
 ├── index.js
 └── test.js

To this:

.
├── alpha
│ ├── data.js
│ ├── index.js
│ └── test.js
└── beta
 ├── data.js
 ├── index.js
 └── test.js

How can I do this in unix?

You can't use wildcards in the target argument. So at least some scripting is required:

for d in *; do
 if [[ -d "$d" ]]; then
 pushd "$d"
 mv __test__/index.js ./data.js
 popd
 fi
done

Here is a example that will move the files.

for f in $(find -name index.js | grep __test__ ); do echo $f; destination=$(echo $f | awk 'BEGINFS="/" print $2'); mv $f ./$destination/data.js; done

I have tested this, it does perform the move as expected.

find . -path '*/__test__/*' -type f -name "index.js" 
 -execdir echo mv -vt ../data.js ;

Remove echo which is for dry-run to run mv command on files.

I forgot about gnu parallel!

ls -d -- */ | parallel "cd && mv ./__test__/index.js ./data.js 2>/dev/null"

Remove echos for the real changing.

for i in */__test__/index.js; do
 echo mv -v "$i" "$i%%/*/data.js"
 echo rm -vr "$i%/*"
done

Before

 └── test.js

After
