1) Find your shell's profile script in your user folder. If you are not sure which shell you have, run echo $SHELL.

$ ls -a ~
.  ..  .bash_logout  .bash_profile  .bashrc  Desktop  Documents  Downloads
Bash – .bash_profile, .profile, or .bash_login.
Zsh – .zshrc
Tcsh – .tcshrc, .cshrc or .login.

2) Add an export command to profile script.

export PATH=~/.local/bin:$PATH
This command adds a path, `~/.local/bin` in this example, to the current PATH variable.

3) Load the profile into your current session.

$ source ~/.bash_profile

export PATH=~/.local/bin:$PATH

$ brew install awsebcli
