让Shell自动找到/home/bill/bin/下的脚本

先在用户目录~下创建bin文件夹,然后只需要在~/.profile文件中设置PATH="$PATH:$HOME/bin;"即可。


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

# This file is not read by bash(1), 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 022



# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"

fi


这样每次登录时Shell都会读取.profile文件
