How do I make this script search through all users' home folders and then `rm -f` the files matching EXT? Right now it's only deleting the files matching EXT in the current folder where I am executing the script. 

```
#!/bin/bash
EXT=jpg
for i in *; do
  if [ "${i}" != "${i%.${EXT}}" ];then
    echo "I do something with the file $i"
    rm -f $i
  fi
done

```
