lua - 如何将 os.execute ("dir") 中的目录信息保存到字符串中？

Question

是否可以保存从os.execute("dir")获取的目录信息转换成字符串形式？

所以在目录<DELL>中我有文件info.txt和readme.txt 。我想使用os.execute("dir")并拥有文件 info.txt和readme.txt保存到字符串 DIR 。所以我猜整个字符串会读成类似 DELL; info.txt, readme.txt .

不，但使用 io.popen应该可以。

io.popen (prog [, mode])

This function is system dependent and is not available on all platforms.

Starts program prog in a separated process and returns a file handle that you can use to read data from this program (if mode is "r", the default) or to write data to this program (if mode is "w").

local p = io.popen( "dir", "r" )
local output = p:read "*a"
p:close( )
-- and use output
