[server check]

不能读取第一个字符

哪来的变量%a%???

即 set "t=%a:~0,1% "%a:~0,2"=="["

我查了很多资料,好像都不对,谢谢

set "t=%a:~0,1% 是想取到serverip.inf中的第一个字符吗？

为何不
set "t=%%a" set "t=%t:~0,1%??

这里"%a:~0,2"=="

变量A在哪...怎么个取法

for /f "tokens=1,2" %%a in (serverip.inf)
从文本中取出[network]放入%%a
然后判断第一个字符是否是[, 就是这样子，
我试了好多办法多实现不了，请指教，谢谢．

试试这样，是可以的：

@set _debug= @echo %_debug% off & setlocal ENABLEDELAYEDEXPANSION for /f "tokens=*" %%i in ('dir /a-d/b') do ( set var=%%i echo !var! --- !var:~0,1!)

如何判断取出的值是"["，我试了，好象报驱动盘符不对，
for /f "tokens=1,2" %%a in (serverip.inf) do (
set t=%%a
!t:~0,1!
echo !t!

ping -n 1 "%%a" | find "out"
if not errorlevel 1 echo Server %%a is in unhealthy condition!>>%yymmddhh%

)

for /f "tokens=1,2" %%a in (serverip.inf) do (
set t=%%a
if "!t:~0,1!" == "["
echo "wonderful"

ping -n 1 "%%a" | find "out"
if not errorlevel 1 echo Server %%a is in unhealthy condition!>>%yymmddhh%

)
我如何做条件判断，echo !t:~0,1!能正确显示结果了，可条件判断该怎么做呢．
谢谢　

这两行应该写在一行：

if "!t:~0,1!" == "["
echo "wonderful"

即：
if "!t:~0,1!" == "[" echo "wonderful"

批处理不是C语言，你不能按照Ｃ的语法去写批处理。

for /f "tokens=1,2" %%a in (serverip.inf) do (
set t=%%a
if "!t:~0,1!"=="["
( echo %%a %%b
)
else(
ping -n 1 "%%a" | find "out"
if not errorlevel 1 echo Server %%a is in unhealthy condition!>>%yymmddhh%
)

)

这样写可以吗,谢谢,好像有问题.有些文章能用ELSE,为什么这里不可以
还有能不能给参考资料看看,关于编写格式方面的,谢谢了.

总算解决了,谢谢climbing

IF EXIST filename. (
del filename.
) ELSE (
echo filename. missing.
)

上面是标准的写法，注意()是怎么用的。

其实没有什么参考资料，最好的参考资料就是微软的帮助。例如：
if /?
