set rel_p=%rel_p:abs_p=%

推荐答案

此脚本生成的

foo \ boo \ bar

foo\boo\bar

set abs_p=C:\abspath\
set rel_p=C:\abspath\foo\boo\bar

set newp=
set rec_a=
set rec_r=

call :strip  %rel_p%\ %abs_p%
goto :END

:strip
set rec_a_part=
set rec_a=
set rec_r_part=
set rec_r=

for /F "tokens=1,* delims=\" %%t  in ("%2") do (
    set rec_a_part=%%t
    set rec_a=%%u
 )
for /F "tokens=1,* delims=\" %%t  in ("%1") do ( 
  set rec_r_part=%%t
  set rec_r=%%u
)
if not !%newp%!==!! set newp=%newp%\
if not !%rec_a_part%!==!%rec_r_part%! set newp=%newp%%rec_r_part%
if not !%rec_r%!==!! call :strip  %rec_r% %rec_a%
goto :EOF

:END
echo %newp%
