平常出bug求助的時候有時候貼代碼或者截圖往往不直觀，如果能重現給對方看就好了，這里推薦 2 個命令行的錄制工具asciinema和TermRecord。

asciinema

網站https://asciinema.org/，github主頁https://github.com/asciinema
直接使用 pip install asciinema來安裝。
執行asciinema rec 開始錄制,錄制完成后 exit 退出，可以保存到本地或者上傳到 https://asciinema.org 。

[root@VM_0_14_centos ~]# asciinema rec asciinema: recording asciicast to /tmp/tmp1ua5a2rx-ascii.cast asciinema: press <ctrl-d> or type "exit" when you're done [root@VM_0_14_centos ~]# pwd /root [root@VM_0_14_centos ~]# cd /usr/share/nginx/html/ [root@VM_0_14_centos html]# pip install asciinema DEPRECATION: Python 3.4 support has been deprecated. pip 19.1 will be the last one supporting it.

[root@VM_0_14_centos html]# exit exit asciinema: recording finished asciinema: press <enter> to upload to asciinema.org, <ctrl-c> to save locallyView the recording at:https://asciinema.org/a/AdnqMX0QfOg5c7USOtwHZ4Hz1This installation of asciinema recorder hasn't been linked to any asciinema.org account. All unclaimed recordings (from unknown installations like this one) are automatically archived 7 days after upload.If you want to preserve all recordings made on this machine, connect this installation with asciinema.org account by opening the following link:https://asciinema.org/connect/01fb0f0e-c56a-450f-80ac-4020188dd957

錄制過程在https://asciinema.org/a/AdnqMX0QfOg5c7USOtwHZ4Hz1 可以看到了。

如果分享給他人可以用郵箱注冊，它不需要密碼就可以注冊。我注冊后的主頁https://asciinema.org/~susheng
然后打開這個鏈接 https://asciinema.org/connect/01fb0f0e-c56a-450f-80ac-4020188dd957 就會保存到你賬號下。

設置為public 后可生成公開鏈接，可分享給他人觀看，還可以嵌入到自己的網站。


視頻鏈接后加 .png 是視頻截圖 https://asciinema.org/a/254348.png ，而鏈接后加 .js 就可以直接嵌入網站了。

<a href="https://asciinema.org/a/254348" target="_blank"><img src="https://asciinema.org/a/254348.svg" /></a> <script src="https://asciinema.org/a/254348.js" id="asciicast-254348" async data-autoplay="true" data-size="big"></script>

TermRecord

TermRecord也是用 pip 安裝 pip install TermRecord, 直接開始錄制 TermRecord -o termrecord.html輸入 exit 結束錄制 。這個 termrecord.html 就是錄制生成的文件，可以直接用瀏覽器打開。

[root@VM_0_14_centos html]# TermRecord -o termrecord.html Script started, file is /tmp/tmpdekpz_p2 [root@VM_0_14_centos html]# pwd /usr/share/nginx/html [root@VM_0_14_centos html]# whoami root [root@VM_0_14_centos html]# pip install TermRecord DEPRECATION: Python 3.4 support has been deprecated. pip 19.1 will be the last one supporting it. Please upgrade your Python as Python 3.4 won't be maintained after March 2019 (cf PEP 429).

You should consider upgrading via the 'pip install --upgrade pip' command. [root@VM_0_14_centos html]# pip list|grep Term DEPRECATION: Python 3.4 support has been deprecated. pip 19.1 will be the last one supporting it.

You should consider upgrading via the 'pip install --upgrade pip' command. [root@VM_0_14_centos html]# exit exit Script done, file is /tmp/tmpdekpz_p2

然后打開文件就可以看到錄制過程了 http://118.24.158.116:8888/termrecord.html

另外還有個基于ruby的showterm和termtosvg就不演示了 http://showterm.io/ https://github.com/nbedos/termtosvg
