Linux终端回话记录和回放工具 - asciinema使用总结

1) 安装Python3环境 (和默认的python版本共存)
[root@localhost ~]# python -V
Python 2.6.6

[root@localhost ~]# yum -y install xz epel-release zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel
[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# wget https://www.python.org/ftp/python/3.5.3/Python-3.5.3.tar.xz
[root@localhost src]# tar -vxf Python-3.5.3.tar.xz
[root@localhost src]# cd Python-3.5.3
[root@localhost Python-3.5.3]# ./configure --prefix=/usr/local/python3
[root@localhost Python-3.5.3]# make && make install

从 Python 3.4 开始就已经自带了pip和easy_install（setuptools 包带的命令） 包管理命令，可以在 /usr/local/python3/bin/ 目录下看到这些安装的扩展包：
[root@localhost Python-3.5.3]# /usr/local/python3/bin/python3 -V
Python 3.5.3

[root@localhost Python-3.5.3]# /usr/local/python3/bin/pip3 -V

创建软链接
[root@localhost ~]# ln -s /usr/local/python3/bin/python3 /usr/bin/python3
[root@localhost ~]# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

查看版本
[root@localhost ~]# python -V
Python 2.6.6
[root@localhost ~]# python3 -V
Python 3.5.3
[root@localhost ~]# pip3 -V
pip 9.0.1 from /usr/local/python3/lib/python3.5/site-packages (python 3.5)

2) 安装asciinema  
[root@localhost ~]# pip3 install asciinema

[root@localhost ~]# find / -name asciinema
/usr/local/python3/lib/python3.5/site-packages/asciinema
/usr/local/python3/bin/asciinema

[root@localhost ~]# ln -s /usr/local/python3/bin/asciinema /usr/bin/asciinema
[root@localhost ~]# asciinema --version
asciinema 2.0.1

查看asciinema帮助信息
[root@localhost ~]# asciinema --help

    upload              Upload locally saved terminal session to asciinema.org    #上传本地保存的终端会话到asciinema.org
    auth                Manage recordings on asciinema.org account             # 管理asciinema.org帐户上的记录

  -h, --help            show this help message and exit
  --version             show program‘s version number and exit       #显示版本号


示例用法: 
记录终端并将其上传到asciinema.org
# asciinema rec   

将终端记录到本地文件
# asciinema rec demo.cast

记录终端并将其上传到asciinema.org，指定标题："my aslog1"
# asciinema rec -t "my aslog1"

将终端记录到本地文件，将空闲时间限制到最大2.5秒
# asciinema rec -i 2.5 demo.cast

从本地文件重放终端记录
# asciinema play demo.cast

重放托管在asciinema.org上的终端记录
# asciinema play https://asciinema.org/a/difqlgx86ym6emrmd8u62yqu8

打印记录的会话的全部输出
# asciinema cat demo.cast
