Important: Premier Support for Oracle Linux 6 is terminated and Oracle Linux 6 is now in Extended Support. See Oracle Open Source Support Policies. Access to patches and fixes for critical security errata and select high-impact critical bug fixes continue to be provided but are limited to the packages listed on the inclusion list at http://linux.oracle.com/es/packagelist.html. Oracle strongly recommends that you migrate applications and data to Oracle Linux 7 or Oracle Linux 8 as soon as possible. Show
Oracle Linux 6 Release NotesImportant: Update releases such as Oracle Linux 6.1 or Oracle Linux 6 Update 1, are rolling snapshots of the latest supported packages for the Oracle Linux release and are not considered independent versions of Oracle Linux. Do not attempt to pin an Oracle Linux system to a particular update release. Always update systems to the most recent update release of the operating system. Failure to do so exposes your systems to common security vulnerabilities and other software bugs.

The /proc filesystem contains many files of varying importance. Get acquainted with the ones you need to know.

As you read in my first article, Exploring the /proc filesystem, the The following is a list of
If you issue a long listing command ( 0 (not shown) file have a zero size. However, these files are not empty. They contain valuable information.
The
And the most valuable of those are 2 and 3.Again, I'm not stating that other files don't have value, but these are the ones I've found that have the most value to me. For example, the 4 file gives you the system's uptime in seconds. For me, that's not particularly valuable. However, if I want that information, I use the 5 command that also gives me a more readable version of 6 as well.By comparison:
I think you get the idea. /proc/cmdlineThis file shows the parameters passed to the kernel at the time it is started.
The value of this information is in how the kernel was booted because any switches or special parameters will be listed here, too. And like all information under 9 for something./proc/cpuinfoThe 0 file is the first file I check when connecting to a new system. I want to know the CPU make-up of a system and this file tells me everything I need to know.
This is a virtual machine and only has one vCPU. If your system contains more than one CPU, the CPU numbering begins at 0 for the first CPU. /proc/meminfoThe 1 file is the second file I check on a new system. It gives me a general and a specific look at a system's memory allocation and usage.
I think most sysadmins either use the 2 or the 3 command to pull some of the data contained here. The 1 file gives me a quick memory overview that I like and can redirect to another file as a snapshot./proc/versionThe 5 command provides more information than the related 6 command does. Here are the two compared:
Usually, the 6 command is sufficient to give you kernel version info but for those of you who are developers or who are ultra-concerned with details, the 5 file is there for you.Wrapping upThe 2 or 3 to get a better picture of system performance rather than reading one of the available /proc files.[ Need to learn more about Linux system administration?

What file in the proc folder contains details about the CPU?/proc/cmdline: it contains the kernel command line details. /proc/consoles: all details about current consoles, such as tty. /proc/cpuinfo: all CPU information gets stored in the file.
What file in the proc directory contains?The /proc/ directory — also called the proc file system — contains a hierarchy of special files which represent the current state of the kernel — allowing applications and users to peer into the kernel's view of the system.
In which directory will you find the Cpuinfo file on most Linux systems?Check the content of /proc/cpuinfo
It's actually a virtual filesystem that contains runtime system information such as system memory, devices mounted, hardware configuration etc. If you want CPU information, you can read the content of the cpuinfo file in proc directory.
Which directory in the Linux root directory contains a file that contains information about the cpus?/proc : /proc, like /dev is a virtual directory. It contains information about your computer, such as information about your CPU and the kernel your Linux system is running.
