Iterate specific files in directory via .bat

I try to create bat file to iterate throuth only files in directory which file names begin with specific word. For Example:
companyName.module1.exe
companyName.module2.dll

I know how to iterate files but don't know how to check their names for specific condition.

Add the following to your batch file:

for /F "eol=: tokens=*" %%A in ('dir /A-D /B "companyName*"') do (echo %%~fA)

This script will echo all files (files only) that begin with companyName prefix in the current working directory. Replace echo with any other command or commands that you want to perform instead.

Update 1: In order to look in a different directory you can either 

for /F "eol=: tokens=*" %%A in ('dir /A-D /B "pathToLookIn/companyName*"') do (echo %%~fA)

or 

pushd \ & cd "pathToLookIn" & (for /F "eol=: tokens=*" %%A in ('dir /A-D /B "companyName*"') do (echo %%~fA)) & popd

Where pathToLookIn is a fully qualified or relative path.

Update 2: I've updated the for /F loop to handle file names that begin with ; as @dbenham suggested.

Well, if you know how to iterate files, then just use that knowledge:

for %%f in (companyName*) do (
  ...
)

Note that iterating over the output of dir is error-prone and will mangle Unicode characters in many cases. Since for is capable of iteration directly there's rarely a need to use a inferior option.
