我目前正在学习 bash 教程:
http://linuxconfig.org/Bash_scripting_Tutorial
我来到了我难以理解的部分:
#!/bin/bash
# bash trap command
trap bashtrap INT
# bash clear screen command
clear;
# bash trap function is executed when CTRL-C is pressed:
# bash prints message => Executing bash trap subrutine !
bashtrap()
{
echo "CTRL+C Detected !...executing bash trap !"
}
# for loop from 1/10 to 10/10
for a in `seq 1 10`; do
echo "$a/10 to Exit."
sleep 1;
done
echo "Exit Bash Trap Example!!!"
你到底在哪里指定 ok 陷阱CTRL+C
?这条线trap bashtrap INT
?INT 意味着什么?
