variable de entorno path

15/01/2004 - 11:06 por jlhortal | Informe spam
Ayuda Hacer una pregunta
En la ayuda de Windows XP Profesional, introduccion a la
shell de comandos, se dice que la longitud máxima de
cualquier variable de entorno es de 8192 bytes. En mi
ordenador la variable PATH se trunca después de 1024

Es esto correcto ?

Hay alguna forma de superar esta limitación ?

Gracias..

Mi anterior respuesta no es del todo correcta...
Efectivamente al hacer "set" también tengo el path con más
de 1024 bytes, pero después de hacer set path= dentro del
shell de comandos.
El problema es entonces que al expandir el path definido
dentro de panel control, sistema, variables de entorno,
cuando arranca el shell, deja truncada path.
Tengo definida Path a través de otras variables, porque
si no en el panel de control tampoco me dejaba pasar de
1024

he ejecutado esto:

set path=%path%;%path%;%path%;%path%;%path%;%path%;%


path%;%path%;%path%;%path%;%path%;

para probar, el el path me lo ha dado mostruoso: sin


limitacion aparente:

echo %path%

En la ayuda de Windows XP Profesional, introduccion a la
shell de comandos, se dice que la longitud máxima de
cualquier variable de entorno es de 8192 bytes. En mi
ordenador la variable PATH se trunca después de 1024

Es esto correcto ?

Hay alguna forma de superar esta limitación ?

Gracias..

Mi anterior respuesta no es del todo correcta...
Efectivamente al hacer "set" también tengo el path con más
de 1024 bytes, pero después de hacer set path= dentro del
shell de comandos.
El problema es entonces que al expandir el path definido
dentro de panel control, sistema, variables de entorno,
cuando arranca el shell, deja truncada path.
Tengo definida Path a través de otras variables, porque
si no en el panel de control tampoco me dejaba pasar de
1024

he ejecutado esto:

set path=%path%;%path%;%path%;%path%;%path%;%path%;%


path%;%path%;%path%;%path%;%path%;

para probar, el el path me lo ha dado mostruoso: sin


limitacion aparente:

echo %path%
