Are you new to LinuxQuestions. Therefore, in this simple yet important guide for new Linux users, I will show you how to do just that. When find is examining a directory, after it has statted two fewer subdirectories than the directory's link count, it knows that the rest of the entries in the directory are non-directories leaf files in the directory tree. Among them should be an entry such as vmlinuz-2. Find Linux kernel using uname command uname is the Linux command to get system information. As well as working across multiple distros. You can view these files using any text editor or the cat command.
All three of these commands do the same thing, but the first one uses the octal representation of the file mode, and the other two use the symbolic form. If only the files' names need to be examined, there is no need to stat them; this gives a significant increase in search speed. These commands all search for files which are writable by either their owner or their group. For symbolic links: if -follow has not been given, true if the file is a link to a file of type c; if -follow has been given, true if c is l. Lastly, to reach us for any assistance or suggestions you wish to offer, make use of the feedback form below. It is also very useful in getting system information. I have a readyNas system that is running some flavor of linux but both methods in this thread don't work.

The command find searches the directory tree rooted at each given file name by evaluating the given expression from left to right, according to the rules of precedence see section on below , until the outcome is known; in other words, the left hand side is false for and operations, true for or, at which point find moves on to the next file name. There are several options available to print out just the kernel details or just the machine information.
Last compilation timestamp is also there. However, if you have previously updated the kernel manually then the information in these files might be wrong. This is a good question, despite what you all might think. Often times I will ssh into a new client's box to make changes to their website configuration without knowing much about the server configuration.

Since dmesg provides quite an awful lot of information, you should use a command like less to read it. The units are 512-byte blocks by default or if b follows n, bytes if c follows n, kilobytes if k follows n, or 2-byte words if w follows n.
In other words, for symbolic links, -xtype checks the type of the file that -type does not check. As I mentionedthere are several ways to find your operating system and Linux kernel versions. Suggested Read: With that said, let us proceed to how you can figure out. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. Because dmesg generates a large amount of output, it is convenient to first transfer that output using a represented by the vertical bar to the grep with the word Linux as an argument in order to display only lines that contain that word and thus the kernel version information as follows: dmesg grep Linux The disadvantages of this method are that it requires some extra typing and that there is still a lot of output to search through even though it has been greatly reduced through the use of the grep filter. To ignore a whole directory tree, use -prune rather than checking every file in the tree.
Linux and Unix operating systems comes in a wide range of flavors often bundled as different distributions by different vendors. Not the answer you're looking for? If you are used to using Windows then a file manager is akin to Windows Explorer.
