pawd

PAWD(1) 						      General Commands Manual							   PAWD(1)

NAME

       pawd - print automounter working directory

SYNOPSIS

       pawd [ path ...	]

DESCRIPTION

       pawd  is used to print the current working directory, adjusted to reflect proper paths that can be reused to go through the automounter for
       the shortest possible path.  In particular, the path printed back does not include any of Amd's local mount points.  Using them is  unsafe,
       because Amd may unmount managed file systems from the mount points, and thus including them in paths may not always find the files within.

       Without any arguments, pawd will print the automounter adjusted current working directory.  With any number of arguments, it will print the
       adjusted path of each one of the arguments.
