       which - Busca una orden

SINOPSIS

       which [-as] filename ...

DESCRIPCIÓN

       which returns the pathnames of the files (or links) which would be executed in the current
       environment, had its arguments been given  as  commands  in  a  strictly  POSIX-conformant
       shell.   It does this by searching the PATH for executable files matching the names of the
       arguments.  It does not canonicalize path names.

OPCIONES

       -a     Muestra todos los nombres de ruta que coincidan con cada argumento.

       -s     silently return 0 if all of the executables were found or 1 otherwise

ESTADO DE SALIDA

       0      Se han encontrado las órdenes definidas, y son ejecutables.

       1      Una o más órdenes no existen, o no son ejecutables.

       2      La opción definida no es válida.
