fixnames.pl

无线通信的主要编程软件,是无线通信工作人员的必备工具,关天相关教程我会在后续传上.

#!/usr/bin/perl -w

# Script to fix files... the automounter makes it nigh impossible to
# get canonical absolute pathnames, so we'll just strip out everything
# up to $USERNAME.

# Input lines of the format:
# number\tpath:number

# Output, same, except that the paths inside the home directory will
# all be of the form ~/blah/blah

use Cwd 'realpath';
