![]() ![]() From here, we can use the arrow keys (or j/k if you’re familiar with Vim) to move through the file, use / to search, and press q to quit. We pass it the filename ( less file.txt), and it will open the file in a simple interface. We could use an editor, although that may be overkill just to view a file. This can be inconvenient when dealing with large files (which isn’t uncommon for logs!). You simply pass in the filename, and it outputs the entire contents of the file: cat file.txt. The most basic way to view files from the command line is using the cat command. The following commands will be useful when working with log files from the command line. This is especially useful when you’re remotely connected to a server and don’t have a GUI. It is also important to know how to view logs in the command line. Viewing and monitoring logs from the command line To view currently logged in users, use the who command. ![]() Login records logĬontains login info used by other utilities to find out who’s logged in. You can view it with the lastlog command. Last logins logĬontains info about last logins. You can view it with the faillog command. Login failures logĬontains info about login failures. Some were made to be parsed by applications. Not all log files are designed to be read by humans. The next display (display 1) would log to Xorg.1.log, and so on. Display numbers start at zero, so your first display (display 0) will log to Xorg.0.log. The X11 server creates a seperate log file for each of your displays. error.log records all errors thrown by the server. The access.log file records all requests made to the server to access files. Location: /var/log/apache2/ (subdirectory)Īpache creates several log files in the /var/log/apache2/ subdirectory. Some applications also create logs in /var/log. If you can’t find anything in the other logs, it’s probably here. Kernel logĬontains more information about your system. Provides debugging information from the Ubuntu system and applications. For example, display server, SSH sessions, printing services, bluetooth, and more. Daemon Logĭaemons are programs that run in the background, usually without user interaction. Keeps track of authorization systems, such as password prompts, the sudo command and remote logins. These logs may contain information about authorizations, system daemons and system messages. System logs deal with exactly that - the Ubuntu system - as opposed to extra applications added by the user. Below is a list of common log file locations. When trying to find a log about something, you should start by identifying the most relevant file. There are many different log files that all serve different purposes. I tried to start it from terminal and got following error.Previous step Next step 2. The icon for System Monitor appears on the launcher but noĪpplication window shows up, and if I click the icon on the launcher.I simply click on the Ubuntu button in the upper left corner to openĭash, type in "monitor" and then click on "System Monitor".I am also eager to learn why the hell it is not starting? This is not reliable, a system component or a program (whatever!) that sometimes starts and sometimes it just wont budge. But I use it for testing and I have all my programs and everything set up now (I did everything the same way as I did five days ago) and for this reason I refrain from rebooting because I would have to do everything all over again. Since it is a Live disc system I could just reboot and see if it starts working again. I boot it with default settings and everything. I know it worked before, some five days ago, and since this is a Live disc system there's no chance in the world that I somehow could have screwed up any system configuration or anything. I have Ubuntu 13.10 Live disc system and for some reason I can't start the System Monitor at the moment. ![]()
