ubuntu非root权限非chsh更改默认shell

参考https://blog.csdn.net/silent56_th/article/details/81367774

默认shell为sh，希望改为bash，修改~/.profile文件，增加两行如下：

# if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
    . "$HOME/.bashrc"
    fi
# modified for changing default shell to bash
else
    export SHELL=/bin/bash
    exec /bin/bash -l
fi

mac上通过homebrew安装redis

brew install redis

开机启动redis命令

停止redis server的自启动
$ launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.redis.plist

卸载redis和它的文件
$ brew uninstall redis
$ rm ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
