Linux CLI - Disk and Storage
What will be the output of the command mount | grep /mnt/usb if the device /dev/sdd1 is mounted on /mnt/usb?
A/dev/sdd1 on /mnt/usb type ext4 (rw,relatime)
BNo output, because grep filters nothing
CError: /mnt/usb not found
Dmount: command not found
Step-by-Step Solution
Solution:

  1. Step 1: Understand the command pipeline

    mount lists all mounts; piping to grep /mnt/usb filters lines containing '/mnt/usb'.

  2. Step 2: Predict output if device is mounted

    If /dev/sdd1 is mounted on /mnt/usb, the output line will show device, mount point, type, and options.

  3. Final Answer:

    /dev/sdd1 on /mnt/usb type ext4 (rw,relatime) -> Option A

  4. Quick Check:

    mount | grep mountpoint = mount info line [OK]
Quick Trick: Use mount | grep to find specific mount info [OK]
Common Mistakes:
  • Expecting no output when device is mounted
  • Confusing error messages with grep output
  • Assuming mount command is missing
