zsh性能分析(没搞完)

~/.zshrc开头加入:

PS4=$'\\\011%D{%s%6.}\011%x\011%I\011%N\011%e\011'
exec 3>&2 2>/tmp/zshstart.$$.log
setopt xtrace prompt_subst

在末尾加入：

unsetopt xtrace
exec 2>&3 3>&-
 

 

zsh -i -c exit
ls -l /tmp/zshstart*.log
/tmp/zshstart.1307531.log
/tmp/zshstart.1317468.log
/tmp/zshstart.1326338.log
/tmp/zshstart.1328497.log
