You need to use command called lsdev. It gathers information about your computer's installed hardware from the interrupts, ioports and dma files in the /proc directory, thus giving you a quick overview of which hardware uses what I/O addresses and what IRQ and DMA channels.

This command is very useful while troubleshooting various hardware conflict problems.

Task display : CPU Information

$ cat /proc/cpuinfo

Task: Display Free and used Memory Information

$ free -m

Task: Display partition information

# fdisk -l

Task: Display file system disk space usage

# df -H
OR
# df -h

Task: Estimate file space usage

# du

Task: List PCI devices

# lspci

Task: List USB devices

# lsusb

Task display : More Information

$ lsdev

Output:
