# 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:

## System Information
- `dmesg`: Displays kernel messages.
- `lscpu`: Shows CPU architecture information.
  Started
- `lsipc`: Lists IPC facilities.
- `lslocks`: Lists system locks.
- `lsmem`: Lists memory ranges and status.
- `lsns`: Lists namespaces.

## Hardware Management
- `chcpu`: Manages CPU state.
- `rtcwake`: Manages system sleep states.
- `zramctl`: Manages zram devices.
- `wdctl`: Shows watchdog status.
- `chmem`: Manages kernel memory usage.

## Filesystem Tools
- `findmnt`: Lists mounted filesystems.
- `mountpoint`: Checks if a directory is a mountpoint.
  Started
- `fsck`: Checks and repairs filesystems.
- `fsfreeze`: Freezes/unfreezes filesystems.
  Done
- `fstrim`: Discards unused blocks on filesystems.
- `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.
- `addpart`: Adds a partition.
- `delpart`: Deletes a partition.
- `partx`: Manages partition entries.
- `resizepart`: Resizes a partition.

## Process and Resource Management
- `runuser`: Runs a shell with different user/group IDs.
- `sulogin`: Provides single-user mode login.
- `chrt`: Manages real-time process attributes.
- `ionice`: Sets process I/O scheduling class/priority.
- `kill`: Sends signals to processes.
- `renice`: Alters process priority.
- `prlimit`: Sets/gets process resource limits.
- `taskset`: Sets/gets process CPU affinity.
- `uclampset`: Manages process utilization clamping.

## User and Session Management
- `su`: Changes user ID or becomes superuser.
- `agetty`: Manages TTYs for login prompts.
- `ctrlaltdel`: Configures Ctrl-Alt-Del action.
- `pivot_root`: Changes the root filesystem.
- `switch_root`: Switches to a different root filesystem.
- `last`: Lists last logged-in users.
- `lslogins`: Displays user information.
- `mesg`: Controls write access to terminal.
- `setsid`: Runs a program in a new session.
- `setterm`: Sets terminal attributes.
- `getty`: Manages virtual console login prompts.

## Networking and IPC
- `ipcmk`: Creates IPC resources.
- `ipcrm`: Removes IPC resources.
- `ipcs`: Shows IPC facilities status.
- `nsenter`: Enters different namespaces.

## Utility Tools
- `lsblk`: Lists block devices.
- `fallocate`: Preallocates file space.
- `flock`: Manages file locks.
- `getopt`: Parses command options.
- `hardlink`: Creates hard links.
- `mcookie`: Generates random numbers.
- `namei`: Follows a pathname to its endpoint.
- `rename`: Renames files.
- `rev`: Reverses lines in a file.
- `setarch`: Sets architecture emulation.
- `setpriv`: Runs a program with different privileges.
- `unshare`: Runs a program with unshared namespaces.
- `utmpdump`: Dumps UTMP/WTMP files.
- `whereis`: Locates binaries, sources, and manuals.
- `ldattach`: Attaches line discipline to a serial line.
- `readprofile`: Reads kernel profiling info.
- `i386, linux32, linux64, x86_64`: Set personality flags for execution environment.
- `uuidgen`: Generate different types of UUID.

Note:
* /bin/more is already implemented in https://github.com/uutils/coreutils
