用户目录下的.profile, 你只需要在用户目录下，创建bin目录，在里面放入你想要执行的可执行文件，就可以在命令行下就可以使用了

# ~/.profile: executed by the command interpreter for login shells.

# This file is not read by bash(), if ~/.bash_profile or ~/.bash_login

# exists.

# see /usr/share/doc/bash/examples/startup-files for examples.

# the files are located in the bash-doc package.

# the default umask is set in /etc/profile; for setting the umask

# for ssh logins, install and configure the libpam-umask package.

#umask 

# if running bash

if [ -n "$BASH_VERSION" ]; then

    # include .bashrc if it exists

    if [ -f "$HOME/.bashrc" ]; then

    . "$HOME/.bashrc"

    fi

# set PATH so it includes user's private bin if it exists

if [ -d "$HOME/bin" ] ; then

.bashrc

# for examples

# If not running interactively, don't do anything
