NAME ^

Linux::MemInfo - Perl extension for accessing /proc/meminfo

SYNOPSIS ^

  use Linux::MemInfo;

ABSTRACT ^

  This module will allow you to easily extract the fields out of the
  /proc/meminfo file.  All of the fields are stored in a hash.

DESCRIPTION ^

    %mem = get_mem_info
    foreach(sort keys %mem) {
        printf("%-20s\t%s\n",$_,$mem{$_});
    }

    Would yield the following:
