# Usage:
|
|
# require "finddepth.pl";
|
|
#
|
|
# &finddepth('/foo','/bar');
|
|
#
|
|
# sub wanted { ... }
|
|
# where wanted does whatever you want. $dir contains the
|
|
# current directory name, and $_ the current filename within
|
|
# that directory. $name contains "$dir/$_". You are cd'ed
|
|
# to $dir when the function is called. The function may
|
|
# set $prune to prune the tree.
|
|
#
|
|
# This library is primarily for find2perl, which, when fed
|
|
#
|
|
# find2perl / -name .nfs\* -mtime +7 -exec rm -f {} \; -o -fstype nfs -prune
|
|
#
|
|
# spits out something like this
|
|
#
|
|
# sub wanted {
|
|
# /^\.nfs.*$/ &&
|
|
# (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) &&
|
|
# int(-M _) > 7 &&
|
|
# unlink($_)
|
|
# ||
|
|
# ($nlink || (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_))) &&
|
|
# $dev < 0 &&
|
|
# ($prune = 1);
