如何使用 hackbench 运行 dohell 命令？

我遗漏了一点关于使用真糟糕命令。请指出。

anisha@linux-dopx:~/Desktop/RealTime/downloadedPages> /usr/xenomai/bin/dohell -b ~/Desktop/RealTime/downloadedPages/hackbench
/usr/xenomai/bin/dohell [ -b path ] [ -s server ] [ -p port ] [ -m mntpoint ] [ -l path | seconds ]

Generate load, using an assorted set of commands and optionnaly:
[B]- hackbench if the path to the hackbench binary is specified with -b;[/B]
- nc to send TCP data to "server" port "port" if -s is specified (if -p
is not specified, the port 9, aka discard is used);
- dd to write data under "mntpoint" if -m is specified.

during the runtime of the LTP test if the path to the LTP installation
directory is specifed with -l or during "seconds" seconds.

hackbench 的类型：

anisha@linux-dopx:~/Desktop/RealTime/downloadedPages> file hackbench
hackbench: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.4, not stripped

我dohell分别尝试了hackbench和seconds参数如下（并且它正常工作）：

linux-dopx:~ # /usr/xenomai/bin/dohell -b
"/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100 seconds" 2
Running with 100*40 (== 4000) tasks.

/usr/xenomai/bin/dohell: line 94: 17276 Terminated              while :; do
   $hackbench 1;
done
/usr/xenomai/bin/dohell: line 94: 17277 Terminated              while :; do
   cat /proc/interrupts;
done > /dev/null 2>&1
/usr/xenomai/bin/dohell: line 94: 17279 Terminated              while :; do
   ps w;
done > /dev/null 2>&1

/usr/xenomai/bin/dohell: line 94: 17281 Terminated              while :; do
   ls -lR / > /dev/null 2>&1;
done
Killed

然后我尝试了同样的方法，xeno-test如下所示：

/usr/xenomai/bin/xeno-test -l "dohell -b
"/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100 seconds" 2"
and
/usr/xenomai/bin/xeno-test -l "dohell -b
/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100 seconds 2"
and
/usr/xenomai/bin/xeno-test -l dohell -b
/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100 seconds 2
and also,
/usr/xenomai/bin/xeno-test -l "dohell -b
/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100" -T 2
and
/usr/xenomai/bin/xeno-test -l "dohell -b
/home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100
process 100" -t 2

所有这些都导致了相同的最终结果：
运行这个的方法是什么？请帮忙。

答案1

最后一个参数是必需的。

如果您有一个使用开关的 LTP 安装，请将其路径传递给它-l，或者传递运行的秒数。

（dohell是普通 shell 脚本，你只要看一下就可以知道它是如何工作的。）

答案2

当然，指定时间长度是必须的，但是

xeno-test -l "dohell -b /home/anisha/Desktop/RealTime/downloadedPages/hackbench -pipe 100  process 100 14400"

仍然没有给出所需的输出。问题在于 hackbench 指定的“参数”。
子dohell命令（带有 hackbench 参数）单独运行良好，但附加时不起作用xeno-test。

我删除了 hackbench 的参数（"-pipe 100 process 100"），然后它开始工作xeno-test。

以下工作：
xeno-test -l "dohell -b /home/anisha/Desktop/RealTime/downloadedPages/hackbench 14400"
