在Bash中,您可以使用`timeout`命令来设置超时限制。这个命令可以在指定的时间内运行一个命令,当时间到达时,它会发送一个信号来终止该命令。以下是如何使用`timeout`命令的示例: ```...
read: read [-ers] [-a array] [-d delim] [-i text] [-n nchars] [-N nchars] [-p prompt] [-t timeout] [-u fd] [name ...] Read a line from the standard input and split it into fields. Reads a single line from the standard input, or from file descriptor FD if the -u...
Read only one character from the terminal and set name to ‘y’ if this character was ‘y’ or ‘Y’ and to ‘n’ otherwise. With this flag set the return status is zero only if the character was ‘y’ or ‘Y’. This option may be used with a timeout (see -t); if the rea...
可见实现1比较快捷,其主要用到了read,关于read的用法还有挺多,详见man bash。 read [-ers] [-a aname] [-d delim] [-i text] [-n nchars] [-N nchars] [-p prompt] [-t timeout] [-u fd] [name ...] One line is read from the standard input, or from the file descriptor fd suppli...

bash语言中有个内置命令read,可以将用户通过键盘输入的内容保存到一个变量中。 [root@localhost tutor]# help read read: read[-ers] [-a array] [-d delim] [-i text] [-n nchars] [-N nchars] [-p prompt] [-ttimeout] [-u fd] [name ...] Read a line from the standard input andspli...
-t timeout Cause read to time out and return failure if a complete line of input is not read within timeout seconds. This option has no effect if read is not reading input from the terminal or a pipe. -a aname The words are assigned to sequential indices of the array variable aname...
while : do read x [ -z "$x" ] && break done 使用数值参数,break可以退出多个嵌套循环: for n in a b c d e do while true do if [ $RANDOM -gt 20000 ] then printf . break 2 ## break out of both while and for loops elif [ $RANDOM -lt 10000 ] then printf '"' break ##...

sleep()基于settimeout 函数 await sleep(1000) nothrow()将 $ 的行为更改, 如果退出码不是0,不跑出异常. ts接口定义 function nothrow<p>(p: p): p await nothrow($`grep something from-file`)// 在管道内:await $`find ./examples -type f -print0` .pipe(nothrow($`xargs -0 grep something`...
