Don't forget Windows shell scripting! #

In response to yesterday's post on sed, Armin Hanisch kindly wrote in to remind us that Windows shell scripts can be handy as well. He included the following shell script version of uniq, which he reports to work under NT4 and higher:


@echo off
if !%1 == ! goto noparm
if not exist %1 goto notfound

setlocal
set line=@@@@@
for /F "usebackq tokens=*" %%f in (`sort %1`) do call :procline "%%f"
endlocal
goto :eof

:procline
if !%line% == !%~1 goto :eof
set line=%~1
echo %~1
goto :eof

:noparm
echo Usage: %~f0 [datei]
echo No file specified, terminating.
goto :eof

:notfound
echo File %1 not found.
goto :eof
