我在10年内没有对批处理文件做过任何事情,但我发现自己需要列出一堆文件的文件大小,名为CG100.mpg虽然CG999.mpg
必须有办法让批处理文件使用FOR循环逐个查看一系列类似命名的文件吗?

如果您能够使用Python,那么以下内容将起作用:
from os.path import getsize
results = [('CG%d.mpg = ' % i) + str(getsize('CG%d.mpg' % i)) for i in range(100, 999)]
print results
否则,对于批处理文件,您可以使用FORFILES:
Select a file (or set of files) and execute a command on each file. Batch processing.
Syntax
FORFILES [/p Path] [/m Mask] [/s] [/c Command] [/d [+ | -] {dd/MM/yyyy | dd}]
Key /p Path The Path to search (default=current folder)
/s Recurse into sub-folders
/C command The command to execute for each file.
Wrap the command string in double quotes.
Default = "cmd /c echo @file"
The Command variables listed below can also be used in the
command string.
/D date Select files with a last modified date greater than or
equal to (+), or less than or equal to (-),
the specified date using the "dd/MM/yyyy" format;
/D + dd Select files with a last modified date greater than or
equal to the current date plus "dd" days. (in the future)
/D - dd Select files with a last modified date less than or
equal to the current date minus "dd" days. (in the past)
A valid "dd" number of days can be any number in
the range of 0 to 32768. (89 years)
"+" is taken as default sign if not specified.
Command Variables:
@file The name of the file.
@fname The file name without extension.
@ext Only the extension of the file.
@path Full path of the file.
@relpath Relative path of the file.
@isdir Returns "TRUE" if a file type is a directory,
and "FALSE" for files.
@fsize Size of the file in bytes.
@fdate Last modified date of the file.
@ftime Last modified time of the file.

绝对有一种使用FOR获取结果的简单方法 - 阅读帮助末尾的FOR循环扩展修饰符 - 从命令行输入HELP FOR
或FOR /?
。
您甚至不需要批处理文件。这个衬管将在命令行中完全按照您的要求执行:
for /l %N in (100 1 999) do @for %F in (GC%N.mpg) do @if exist %F echo %F size = %~zF
如果在批处理文件中使用该命令,请将所有%
更改为%%
。
如果您只想列出与模式GC*.mpg
匹配的所有文件的大小,该命令会更简单:
for %F in (GC*.mpg) do @echo %F size = %~zF
