I'm pretty new to linux. Just wondering if there is a command for linux to print up a list of hardware specs on a computer, also giving information on if the hardware is working properly or not. I'm using Knoppix 3.3. Thanks in advance.

You mean you don't know what hardware is in your computer? Here are a few bash commands for finding out stuff.

Handy bash commands for finding out stuff in Linux:
# Find CPU specifications
cat /proc/cpuinfo

# Find running kernel version
uname -r

# What compiler version do I have installed
gcc -v
gcc --version

# What is the running kernel and compiler installed
cat /proc/version

# Find X server version
X -showconfig

# What pci cards are installed and what irq/port is used
cat /proc/pci

# What kernel modules are loaded
lsmod

# Memory and swap information
cat /proc/meminfo
free
An article: Tips for Optimizing Linux Memory

# How are the hard drives partitioned
fdisk -l

# How much free/used drive space
df -h

# Show disk usage by current directory and all subdirectories
du | less

# What takes up so much space on your box
# Run from the directory in question and the largest chunk shows up last
find $1 -type d | xargs du -sm | sort -g

# What is the distribution
cat /etc/.product
cat /etc/.issue
cat /etc/issue
cat /etc/issue.net
sysinfo

# For finding or locating files
find
locate
which
whereis

# Use dmesg to view the kernel ring buffer (error messages)
dmesg | less

# Watch error messages as they happen (sysklog needed)
as root, tail -f /var/log/messages (shows last 10 lines, use a number in front of f for more lines)

# What processes are running
ps -A

# Find a process by name
ps -ef | grep -i <plain text>
For example, XCDroast
ps -ef xcdroast

# See current environment list, or pipe to file
env | more
env > environmentvariablelist.txt

# Show current userid and assigned groups
id

# See all command aliases for the current user
alias

# See rpms installed on current system
rpmquery --all | less
rpmquery --all > <filename>
rpmquery --all | grep -i <plaintext>

Autospec for tarballs
RPM tools

# What directory am I using
pwd

# Get ls colors in less
ls --color=always | less -R

Look at man <command> or info <command> for the flags I used and for other options you can use for bash commands.

you can try below commands to get hardware details.
lspci
/proc
dmidecode
hwinfo

This article which I referred have linux hardware information

Thanks for the great link!! I want to find the GUI version of lshw!!

Normally, it's not good to reopen (very) old threads----but I think this is an exception.

This is a nice tutorials for hardware related commands:

There are a number of ways to check what hardware you have in Linux. These are all important to know when configuring a kernel from source before compiling it. I will be covering commands for finding hardware information because that's what you asked for, not information about your software like the first guy posted.

There may be more that are just a google search away, and they might just give you the same info as the ones above do.

To see drivers (kernel modules) in use, use

On my machine, here is a snip of the output.

You can see the kernel module (driver) in use is snd-hda-intel. This is extremely useful when compiling a kernel to know what to include in your kernel config. Most everything should be compiled directly into the kernel for your specific hardware. That will result in a much faster more efficient kernel.

For a few devices that are not always in use such as my usb webcam, I left it as a module, so that it only loads when in use. This is just my preference. You can do it either way.

If you plugin hardware such as a usb device while Linux is running, information about it will show in

lshw -html > myhardware.html

Now you can open that file with a GUI such as firefox or your web browser of choice.

Sorry I mean to edit a different thread. Not sure how to delete this now :-)

Hey, I'm glad you got the wrong thread! Looking over this older stuff, I learned something new. Thanks

Coordially,
