It appears to be corrupt or improperly formatted. Maybe something is wrong with transferring.

E[x]tract an archive to [o]utput directory:

可能有用

分离conda启动脚本, 加快zsh启动速度

title

平时使用中发现zsh启动延迟大到需要等上好几秒，翻过改的乱七八糟的zshrc发现是conda在拖慢启动速度。

虽然最便捷的方法是不用conda，但作业又经常用到conda的环境。

这里选择为conda绑定alias，在需要时启动。

# in .zshrc add

alias ci='source  ~/.config/zsh/conda.zsh'
