[文本处理] [已解决]如何判断输入字符的个数（长度）是否小于指定值？

@echo off&setlocal enabledelayedexpansion
set "name=123456987654"
set "name=%name: =%"
for /l %%n in (0,1,8192)do (
 if not "!name:~%%n,1!"=="" set/a "n=1+%%n"
)
echo,%n%
pause
复制代码

powershell -c "'1234567abc呵呵'.Length"
复制代码

echo;1234567abc呵呵|gawk -F "" "{print NF}"
echo;1234567abc呵呵|gawk "{print length($0)}"
复制代码

set str=1234567abc呵呵
mshta "javascript:new ActiveXObject('Scripting.Filesystemobject').GetStandardStream(1).Write('%str%'.length);close()"|more
复制代码

set /p s=Input:
if not "%s%" == "" if not "%s:~5%" == "" echo 不小于6个字符
复制代码

:strlen_loop
if "!card:~%n%,1!" neq "" set /a n+=1&goto strlen_loop
endlocal&set "%~1=%n%"&goto :eof
