Ubuntu无ROOT权限安装、优化和使用Screen
安装Screen
一:如果有 Conda 环境:
conda install -c conda-forge screen二:从源码编译安装
1.创建本地安装目录
mkdir -p ~/local/srccd ~/local/src2.下载 Screen 源码,以 4.9.0 为例
wget https://ftp.gnu.org/gnu/screen/screen-4.9.0.tar.gztar -xzvf screen-4.9.0.tar.gzcd screen-4.9.03.配置并指定安装路径
./configure --prefix=$HOME/local4.编译并安装
makemake install5.配置环境变量
echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrcsource ~/.bashrc配置Screen
在你的用户主目录下创建或编辑配置文件.screenrc:
vim ~/.screenrc在配置文件中写入内容:

已经运行中的会话,需要:
1.在 Screen 会话中,按下 Ctrl + a。
2.松开手,输入 : (冒号,进入 Screen 的命令行模式)。
3.输入以下命令并回车:source ~/.screenrc使用Screen
新建命名会话:
screen -S <name>列出所有会话:
screen -ls恢复会话:
screen -r <id或name>强制恢复:
screen -d -r <id或name>关闭会话:
screen -X -S <name> quit Ubuntu无ROOT权限安装、优化和使用Screen
