bash - Windows batch version of Unix select command? -


i'm trying create windows version of simple bash script have, cannot seem find windows version of unix 'select' command. there one?

here's script:

#!/bin/bash  echo "enter number of file want select:"  select the_file in somedir/*;     echo "you picked $the_file ($reply)"     # stuff here.     break; done

it easy find linux example, bit perplexed cannot seem find windows equivalent.

edit: select command prompts user select file given directory (that's oversimplification). clarify, script above produce following output, assuming there subdirectory 'somedir' 3 text files in it.

enter number of file want select: 1) somedir/somefile1.txt 2) somedir/somefile2.txt 3) somedir/somefile3.txt #? 2 picked somedir/somefile2.txt (2)

windows batch commands not include equivalent select command. have build own version.

you need:

  • call command. create subroutine , reuse it
  • for command iterate on files, or for /f iterate on output of command returning list of files
  • for short lists, choice command more friendly user not needed press enter, longer lists or if don't know number of files select, set /p better option

here, sample

@echo off     setlocal enableextensions disabledelayedexpansion      call :select "somedir\*" the_file     echo picked %the_file%      goto :eof   :select mask returnvar     setlocal enableextensions disabledelayedexpansion      rem configure internal variables     set "filenumber="     set "maxfiles=-1"     /f "delims==" %%a in ('2^>nul set f[') set "%%a="      echo enter number of file want select:      rem search files, show list , create array file list     rem using xcopy list of files because show     rem relative paths when relative mask used input      /f "tokens=1,* delims=:" %%a in ('         xcopy "%~1" "%temp%" /l ^| findstr /n /r /c:"[\\\.:]"     ') (         echo %%a^) %%b         set "f[%%a]=%%~fb"         set "maxfiles=%%a"     )      rem prompt      :select.ask     set /p "filenumber=#? "      rem validate input     set /a "filenumber=filenumber+0" 2>nul     if %filenumber% gtr %maxfiles% set "filenumber=-1"     if %filenumber% lss 1 set "filenumber="     if not defined filenumber (         echo wrong selection         goto :select.ask     )      rem retrieve file array     setlocal enabledelayedexpansion     %%a in ("!f[%filenumber%]!") (         endlocal          set "selectedfile=%%~a"     )      rem return selection caller     endlocal & set "%~2=%selectedfile%"     goto :eof
