shell 捕获ctrl信号脚本

!/bin/bash

捕获ctrl+c信号时，执行echo命令

trap 'echo "you are typing ctrl-c ,sorry,script will not terminate"' INT

捕获Ctrl+\信号，执行echo

trap 'echo "you are typing ctrl-\ ,sorry,script will not terminate"' QUIT

捕获ctrl+z信号，就会执行echo命令 （实测此处没有执行echo命令）

trap 'echo "you are typing ctrl-z ,sorry,script will not terminate"' TSTP

while true do echo "now , test signal $(date)" sleep 5 done
