Quickly list and query active mount points to pinpoint mounts and devices. 16.01.2026 | reading time: 2 min When an admin needs to know what is mounted and where, he runs findmnt to get a clear, machine-friendly view of active mountpoints and their sources. Locate a specific mount quickly Try this on a system where "/data" should be mounted; it shows the command and the expected output in one glance: ```$ findmnt -o TARGET,SOURCE,FSTYPE,OPTIONS --target /data TARGET SOURCE FSTYPE OPTIONS /data /dev/sdb1 ext4 rw,relatime,data=ordered ``` Filters and output tricks to shape results Use options to ask exactly what you need: `--target` or `-T` to query a path, `--source` or `-S` to query a device, `-t` to filter by filesystem type, `-o` to select columns, `-n` to omit headers and `-r` for raw output; combine these to script checks or produce parsable reports. When to reach for findmnt Reach for findmnt when you require a concise view of active mounts, when you must resolve which device backs a path, or when you need formatted output for automation; for quick human-readable trees just run `findmnt` without options. Wrap-up and next steps You have a fast way to verify mounts and to script checks around storage and fstab changes; dig deeper by combining findmnt with lsblk or fstab edits and practise on a lab system to gain confidence; consider formalizing that skill with courses and exam prep such as bitsandbytes.academy for CompTIA Linux+ or LPIC-1.
