> allow any user script to be able to override system commands Other users could only override system commands if they can write files to your ~/.local/bin As /u/CJefferson pointed out, if a user has permission to write files to your ~/.local/bin, they can probably also write to your ~/.profile and ~/.bash_profile. As long as you control the contents of your home directory, modifying your $PATH to include ~/.local/bin is safe.
