# util-linux
|
|
|
|
This projects aims at doing the same as https://github.com/uutils/coreutils for util-linux.
|
|
|
|
We are rewriting [these tools](https://github.com/util-linux/util-linux) in Rust as drop-in replacements.
|
|
|
|
First, reimplement the most important tools from util-linux:
|
|

|
- `dmesg`: Displays kernel messages.
|
|
- `lscpu`: Shows CPU architecture information.
|
|
Started
|
|

|
|
- `lsns`: Lists namespaces.
|
|
|
|
## Hardware Management
|
|
- `chcpu`: Manages CPU state.
|
|
- `rtcwake`: Manages system sleep states.

|
- `zramctl`: Manages zram devices.
|
|
- `wdctl`: Shows watchdog status.

|
|
|
|
## Filesystem Tools
|
|

|
|
- `wipefs`: Wipes filesystem signatures.
|
|
|
|
## Partition Management
|
|
- `blkdiscard`: Discards sectors on a device.
|
|
- `blkid`: Identifies block device attributes.
|
|
- `blkzone`: Manages zoned block device parameters.
|
|
- `blockdev`: Performs block device operations.
|
|
- `mkswap`: Sets up swap space.
|
|
- `swaplabel`: Manages swap space labels.
|
|
