是否有相当于linux屏幕命令的solaris?
示例如何在Linux中使用screen命令
example for linux : screen -D -m ./run_some_script.pl
example for Solaris : ?

我不知道subprocess.call()的返回值是什么意思。
我能安全地假定零值总是意味着命令执行成功吗?
返回值是否等效于shell命令的退出主存?
例如,下面的代码是否适用于Linux上的几乎任何命令?
cmd = "foo.txt > bar.txt"
ret = subprocess.call(cmd, shell=True)
if ret != 0:
if ret < 0:
print "Killed by signal", -ret
else:
print &
如何在windows中使用Runtime.getRuntime().exec(命令)?
1.
command = "cat data.json"; // works in linux terminal
Runtime.getRuntime().exec(command) // runs in linux => Runs OK
2.
command = "type data.json"; // works in windows cmd
Runtime.getRuntime().exec(command) // runs in windows => F
我正在尝试将如下所示的Python代码移植到Ruby中:
import pty
pid, fd = pty.fork
if pid == 0:
# figure out what to launch
cmd = get_command_based_on_user_input()
# now replace the forked process with the command
os.exec(cmd)
else:
# read and write to fd like a terminal
因为我需要像读写终端一样读写子进程,所以我知道我应该使用Ruby模块来代替Ker
