Edited from the original question by Bob Altman in
alt.msdos.batch.nt
I call a batch file like this: DoSomething c:\a\b\c\d
I need to parse the specified path and execute a command for each
folder in the path containing the specified file. The order of
execution doesn't matter. So, for the above example, I need to do
the following:
SomeCommand c:\a
SomeCommand c:\a\b
SomeCommand c:\a\b\c
With a generic rather than customized parsing
view we can use e.g.
@echo off & setlocal enableextensions
enabledelayedexpansion
set var=C:\a\b\c\d
rem the above might alternatively be:
rem set var=%~1
::
:: Parse
set count_=0
set rest_=%var%
:_loop
for /f "tokens=1* delims=\" %%a in ("%rest_%") do (
set /a count_+=1
set var[
!count_
!]=%%a
set rest_=%%b
if defined rest_ goto _loop
)
::
:: Display the individual parts
for /l %%i in (1,1,%count_%) do echo var[%%i]=!var[%%i]!
echo.
::
:: Display combined
for /l %%i in (1,1,%count_%) do (
set composite_=!composite_!!var[%%i]!\
if %%i GTR 1 echo Whatever !composite_:~0,-1!
)
::
endlocal & goto :EOF
The output would be
C:\_D\TEST>cmdfaq
var[1]=C:
var[2]=a
var[3]=b
var[4]=c
var[5]=d
Whatever C:\a
Whatever C:\a\b
Whatever C:\a\b\c
Whatever C:\a\b\c\d
Note how the solution also gives the method for counting the number
of words in a variable or on a line
@echo off & setlocal enableextensions
set var=%~1
::
:: Parse and count
set count_=0
set rest_=%var%
:_loop
for /f "tokens=1*" %%a in ("%rest_%") do (
set /a count_+=1
set rest_=%%b
if defined rest_ goto _loop
)
::
:: Display the result
echo
.%var%
echo The number of words is %count_%
endlocal & goto :EOF
For example
C:\_D\TEST>cmdfaq "Asterisk means the remaining text on the line"
Asterisk means the remaining text on the line
The number or words is 8
The solution also gives the method to get the last word of a line:
@echo off & setlocal enableextensions
set var=%~1
::
:: Parse
set rest_=%var%
:_loop
for /f "tokens=1*" %%a in ("%rest_%") do (
set rest_=%%b
set last_=%%a
if defined rest_ goto _loop
)
::
:: Display the result
echo
.%var%
echo The last word is "%last_%"
endlocal & goto :EOF
For example
C:\_D\TEST>cmdfaq "Asterisk means the remaining text on the line"
Asterisk means the remaining text on the line
The last word is "line"
