My 10 UNIX Command Line Mistakes – nixCraft

Posted by jpluimers on 2019/01/28

An interesting series of mistakes that anyone can make followed by a long thread of discussion with various people making mistakes on many operating systems:

My top 10 biggest UNIX / Linux command-line mistakes that cause some sort of down time. Try to avoid them.

[WayBackMy 10 UNIX Command Line Mistakes – nixCraft


All men make mistakes, but only wise men learn from their mistakes — Winston Churchill.
From all those mistakes I have learn that:

  1. You must keep a good set of backups. Test your backups regularly too.
  2. The clear choice for preserving all data of UNIX file systems is dump, which is only tool that guaranties recovery under all conditions. (see Torture-testing Backup and Archive Programs paper).
  3. Never use rsync with single backup directory. Create a snapshots using rsync or rsnapshots.
  4. Use CVS/git to store configuration files.
  5. Wait and read command line twice before hitting the dam [Enter] key.
  6. Use your well tested perl / shell scripts and open source configuration management software such as puppet, Ansible, Cfengine or Chef to configure all servers. This also applies to day today jobs such as creating the users and more.

Mistakes are the inevitable, so have you made any mistakes that have caused some sort of downtime? Please add them into the comments section below.

I didn’t know about rsnapshots, so I need to put some research in it, hence the links below.

Note that the rsnapshots documentation is a bit behind the source code, so if you look for the HOWTO, then you’ll get a 404. The old HOWTO is in a link below.

ScanSnap ix100 info you don’t find in the Getting Started guide easily

Posted by jpluimers on 2019/01/28

Always fun when Getting Started guide makes it hard to find essential information, but the installation mentions it after installing:

ScanSnap is initially set to turn off automatically after a certain time of non-activity.
The power-off interval can be changed from the [ScanSnap Manager – Preferences] window.

To turn the ScanSnap back on, perform one of the following:

  • Press the [Scan] button
  • Close the ADF paper chute (cover) and open it again

The installer then continues to ask to connect it over USB, though the Getting Started guide mentions you can connect over WiFi.

There the “monkey gets out of the sleeve” as the WiFi installer mentions this:

ScanSnap Wireless Network Setup

To start up the Wireless Setup Tool, perform the following:

  • Turn on ScanSnap
  • Turn on the Wi-Fi switch on the ScanSnap
  • Connect ScanSnap to the computer via the USB cable

(i) If you start up the Wireless Setup Tool via Wi-Fi, some functions are not available.

Too bad it doesn’t explain which functions are not available, not even a web-search or the [WayBack] manuals:
