Let us take a look at the fields present in the syntax of the lshw command:<\/p>\n
<options><\/strong><\/p>\n This field takes in a variety of options that specify how the zip command should function, format, and print the output. You can also specify multiple options in this field.<\/p>\n <format><\/strong><\/p>\n This field specifies the format in which the lshw must print the output. You can specify any of the following four format specifiers in this field.<\/p>\n 1. -html<\/strong>: Output hardware tree as HTML. The lshw command has only a couple of options. Here are some of the most used ones in this section, and cover the remaining on the fly as we look at some examples in the subsequent section.<\/p>\n 1. -enable<\/strong><\/p>\n This option enables different parameters of the system. It is the complete opposite of the “–disable” command.<\/p>\n 2. -disable<\/strong><\/p>\n This option disables various parameters of the system. It is the complete opposite of the “–enable” command.<\/p>\n 3. –help<\/strong><\/p>\n This option prints the help menu of the lshw command, as shown below:<\/p>\n 4. -numeric<\/strong><\/p>\n This option displays and prints out numeric ID’s for fields like PCB, USB, and more.<\/p>\n 5. -sanitize<\/strong><\/p>\n This option prints the output without any sensitive information. If you want to print the information of your system’s hardware configuration without displaying any private and sensitive information, use the lshw command along with the “–sanitize” option.<\/p>\n 6. -c<\/strong><\/p>\n This option displays only the class of hardware you specified.<\/p>\n 7. -quite<\/strong><\/p>\n This option hides the display status.<\/p>\n 8. -notime<\/strong><\/p>\n This option excludes volatile attributes from the output.<\/p>\n Now, let us look at some Practical examples of the lshw command in the terminal of Ubuntu 20.04.<\/p>\n To display complete hardware information of your computer, use the lshw command with no options and format specifiers.<\/p>\n To change the format of the output and print it in HTML format, use the lshw command followed by the format specifiers “-html” as shown:<\/p>\n To change the output format and print it in XML format, use the lshw command followed by the format specifiers “-xml” as shown:<\/p>\n To change the output format and print it in JSON format, use the lshw command followed by the format specifiers “-json” as shown:<\/p>\n If you want to display the paths of the hardware, run the lshw command by combining it with the format specifier “-short” as shown:<\/p>\n If you want to display the bus information that gives more details on the sections SCSI, USB, IDE, and PCI addresses, run the lshw command by combining it with the format specifier “-businfo” as shown:<\/p>\n If you want to display a specific class of hardware, execute the lshw command by pairing it with the option “-c” followed by the class of hardware on which you want to see the information.<\/p>\n If you want to print the system information, couple the lshw command with the option “-class” followed by the “system” class of hardware as shown:<\/p>\n To display the system information, couple the lshw command with the option “-class” followed by the “display” class of hardware as shown below:<\/p>\n To display the network information, couple the lshw command with the option “-class” followed by the “network” class of hardware as shown:<\/p>\n To display the storage information, couple the lshw command with the option “-class” followed by the “storage” class of hardware as shown:<\/p>\n To display the disk information, couple the lshw command with the option “-class” followed by the “disk” class of hardware as shown:<\/p>\n To display the processor information, couple the lshw command with the option “-class” followed by the “processor” class of hardware as shown:<\/p>\n To display the motherboard information, couple the lshw command with the option “-class” followed by the “bus” class of hardware as shown:<\/p>\n We can save the output of the lshw command in a separate file by making use of the redirection operator as shown in the syntax below:<\/p>\n Pairing the lshw command with the option “–enable” lets us enable various system parameters. These parameters include dmi, Device-tree, Spd, Memory, cpuinfo, cpuid, pci, isapnp, pcmcia, ide, usb, scsi, and network.<\/p>\n Just like enabling, disabling is also extremely easy. All you have to do is replace the option “-enable” with “-disable,” as shown in the syntax below:<\/p>\n If you don’t want the status displayed in the output, run the lshw command along with the option “-quiet” as shown:<\/span><\/p>\n As we saw above, to hide sensitive or private information like IP addresses, serial numbers, etc., use the option “-sanitize” as shown:<\/p>\n
\n2. -xml:<\/strong> Output hardware tree as XML.
\n3. -short:<\/strong> Output hardware paths.
\n4. -businfo<\/strong>: Output bus information.
\n5. -json:<\/strong> Output device tree as a JSON object.<\/p>\nOptions used with linux lshw command<\/h3>\n
