AFS::Cell(3) Module to administer AFS Cells


use AFS::Cell qw (configdir expandcell
getcellinfo localcell
whichcell wscell
my $conf_dir = configdir;
my $cell = expandcell('mpa');
$cell = localcell;
$cell = whichcell('./');
$cell = wscell;
($cell, my @hosts) = getcellinfo;
print "Cell: $cell\n";
foreach my $host (@hosts) {
print(" $host\n");


This module provides several functions to configure and to maintain an AFS cell. It is used to maintain the configuration directory. Any function required must by explicitly listed by the "use" statement to be exported into the calling package.

Some of these functions have the optional argument FOLLOW. FOLLOW determines which file should be used should PATH be a symbolic link. If FOLLOW be set to 1, then the symbolic link is followed to its target. If FOLLOW is set to 0, then the function applies to the symbolic link itself. If not specified FOLLOW defaults to 1.


This release does NOT support any features and interfaces from version 1.
