command not found…

Which command will display the number of devices in my system (routers/switches/AP)

I purchased the Hp 15-n018 model laptop, when i checking with vendor they said will not support for Linux operating and i didn’t found the driver in internet….. i able found in win 8 and 8.1….
But am very interested in Linux operating system…. any one can please help me where i can the driver.

Sudinhar: it really depends on what driver you’re talking about for which specific device and for which specific Linux distribution.
The laptop itself may require any number of drivers, including HD, CD/DVD, sound, display, network, etc.
Many Linux distributions come with drivers for a wide variety of systems & devices, and you can generally get Linux up & running on just about anything these days with enough patience.
You can generally repartition your hard drive without losing any data using tools provided in distribution ISOs/DVDs & install Linux as a dual boot without fear of not being able to also use Windows if necessary as a backup.
I first installed Linux on a laptop back in the 90s, and it was difficult to get all the drivers but I did eventually & it worked ok.
These days it’s usually much simpler and any up to date Linux distribution should run just fine on your laptop with a little setup & TLC.

As a side note, I’d like to thank the author of this article, the commands worked as advertised & provided the information I required.

Linux has a long history of not “playing well” with laptops, and unless you get a laptop that is “certified” to run with Linux, you’re bound to have headaches. Something else you might try is keeping the laptop as is, and installing Virtual Box, by Sun (Oracle?) I believe it’s available on-line at no charge. This is a VM system, which will allow you to load a real copy of Linux, as it emulates a real computer. Personally, I use VMware Workstation (I’ve had it for years, but it’s a commercial product) which does the same thing, but I’ve heard nothing but good things about Virtual Box. You can then launch Linux in a window, and it’s a “real” linux version, which you will install from the distribution ISO.

Let’s say I want to display on the i3status bar whether a device/share is mounted.
How would that be accomplished?

I’m kind of new to i3, but as of what I’ve found online about the wm, it is a matter of finding the right parameter on i3status or i3blocks (whichever you use).

How to Check if a Filesystem is Mounted in Linux?

To start working, you must have any Linux distribution installed on your system. Login from your Linux system and open the command terminal. Make sure you have the “util-linux” package installed on your system to start checking the mounted filesystem. For this purpose, try the below “apt” command followed by the keyword “install” in a shell. Instantly, the installation will be completed, and you can now check the mounted filesystem.

There are many methods available to check the file system on your system. We will illustrate each one of them one by one.

Method 01: Using Findmnt Command

Our first and most used way in the Linux system to know the filesystem type is the “findmnt” command. The “findmnt” command helps us find all the mounted filesystems. Let’s start working on it. To see the list of mounted filesystems, type the simple “findmnt” command in the shell as below, which will list all the filesystems in a tree-type format. This snapshot contains all the necessary details about the filesystem; its type, source, and many more. It is clear from the image that our main filesystem is “ext4”.

Let us display the filesystems in a simple format using the below “findmnt” command with a “-l” flag.

We can list the type of our mounted filesystem using the findmnt command along with the “-t” flag followed by the name of the filesystem, e.g., “ext4”. So, execute the below-stated command in the shell. The output shows the information regarding the “ext4” filesystem.

To see the “df” style list of output about the filesystem, you have to use the below command. You can see that it will show extra information regarding the filesystems and their sources.

You can use the modified form of this command as follows:

If you want to search for the configured filesystem in a particular device, you can do so using the below command. You can see that the output shows the “vfat” type filesystem for the specific device.

If you want to see the mount point of a filesystem, try using the below “findmnt” command followed by the backslash “/” sign.

If you want to know more details about the filesystem, use the man command as follows:

The output is shown below.

Method 02: Using Blkid Command

In most cases, the “findmnt” command will be enough in knowing the filesystem’s type, but there are some alternative commands for this purpose. One of them is the “blkid” command which we don’t need to mount. After the execution of the “blkid” command below, along with the “sudo” keyword, we will be able to display all the block devices along with the filesystem type.

We can use the “blkid” command to know the filesystem for the particular device.

To see extra details about the filesystem, try the below command:

For further details try the man command below:

The output is given below.

Method 03: Using DF Command

The DF command is cast-off to know the disk space usage of the filesystem. Use it with the “-T” flag to know all the filesystem’s types.

Go through the man page to know more.

The detail is given in the snapshot.

Method 04: Using File Command

Another method to check the mounted file system is using the “file” command in the shell. You can use it for files having no extension. Hence, execute the below command to know the filesystem for a partition. It may require your password to function.

To have extra information, try the below man command in the shell.

You can see the details on the main page as shown in the appended image.

Method 05: Usinf Fsck Command

The “fsck” command may be used to verify or restore the reliability of a filesystem by providing the partition as an argument. You will decide what sort of filesystem it is.

For further details, have a look at the main page.

And you can see the details shown below.

Method 06: Using Fstab Command

Another new way to view the filesystem is using the “fstab” in the cat command. Therefore, try executing the below cat command in the shell.

For extra details, try the same man command along with the keyword “fstab”.

Now you will be having details about the filesystem, as shown in the image attached.

Method 07: Using Lsblk Command

The “lsbkl” command will show the filesystem types and the devices.

Run the below man command to see the details.

And the extra information regarding the filesystem is displayed below.

Method 08: Using grep Command

Last but not least, the “grep” command is used to check the filesystem.

Conclusion:

We have done all the commands to check the mounted filesystem. I hope you can easily check the mounted filesystem in your Linux distribution.
