SMB Caching Jun 1st by Tony Lawrence
A customer had a particular shared folder setup so that only he had access to it. This happened to be a SCO Visionfs system, but you could run into similar problems with Samba. |

Mound --Bind Apr 29th by Tony Lawrence
Most Linux and Unix file systems don't allow hard links to directories (except for the . and .. entries that mkdir creates itself). The reasons are are pretty obvious: you could really confuse programs like ls (ls -R), find and of course fsck if you created links that recursed back to themselves. |

Tar Wild Card Interpretation Apr 23rd by Tony Lawrence
I had this email earlier this week:I am trying to restore a file "\GL050". I can see it on the tape listing, but I can't get edge to find it. I have tried listing it the following ways: |

Lost Root Password - Linux Apr 13th by Tony Lawrence
Have you ever forgotten your root password? I have a very good memory. I remember most of my client's passwords (there are a few I forget regularly for no reason that I can understand, but I really do know most), I remember telephone numbers, and of course I know my own passwords. |

Enabling Linux Telnet Mar 8th by Tony Lawrence
This has to be one of the more common support calls that I get. The telnet daemon is no longer usually installed by default, so people are surprised when their newly installed Linux system won't answer telnets. |

Undoing Bad Archives Oct 19th by Tony Lawrence
Most zip or tar archives are made so that they unpack into a sub-directory. However, every now and then you run into one that wasn't done that way, and if you happen to unpack it in a directory that already has files, you end up with confusion: what was just unpacked and what was already here? |

ps sorting Sep 2nd by Tony Lawrence
In the beginning, when large creatures lumbered through damp tropical forests and furry mammals hid quivering in their burrows, "ps" had no built in abilty to change its sort order. You got what it gave, and if you wanted it otherwise, you ran it through "sort" yourself. That is the Unix Way: small tools, working together... |

Bash Aliases Sep 2nd by Tony Lawrence
Most shells have some provision for aliases. Aliases can assign default behavior to a command (for example "rm" is often aliased to "rm -i") or can be used to create new commands (a typical example is "ll" aliased to be "ls -l"). |

How to Build Your Own Linux Distribution Jul 6th by Frank Pohlmann
Linux® From Scratch (LFS) and its descendants represent a new way to teach users how the Linux operating systems work. LFS is based on the assumption that compiling a complete operating system piece by piece not only teaches how the operating system works but also allows an independent operator to build systems for speed,... |

Monitor Linux File System Events with Inotify May 31st by Eli M. Dow
Inotify is a file system event-monitoring mechanism slated for inclusion in upcoming Linux™ kernels that is designed to serve as an effective replacement for dnotify, which was the de facto file-monitoring mechanism supported in older kernels. Inotify is a powerful, fine-grained, asynchronous mechanism ideally suited for a... |

PATH, Command May 13th by Tony Lawrence
Your PATH (echo $PATH) is where your shell will search for executables. If a command you want to run isn't included in $PATH, you have to be specific: /somewhere/someprog. One confusion for Unix/Linux newcomers is that if PATH doesn't include "." (current directory), then trying to run a program you can see right in front... |

Loglevel May 13th by Tony Lawrence
Syslog is a wonderful thing. In theory, it lets an administrator fully control where and how messages get logged. Of course, the first requirement is that the program you wish to control uses syslog for logging, but even assuming that it does, it can still be difficult to get what you want. |

Higher Order Functions May 13th by Jonathan Bartlett
Functions are the wonderful and powerful building blocks of computer programs. Functions allow you to break code down into simpler, more manageable steps. They also allow you to break programs into reusable parts -- parts that are both reusable within the program and in other programs as well. In this article, learn how to... |
