util-linux

This projects aims at doing the same as https://github.com/uutils/coreutils for util-linux.

We are rewriting these tools 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.
• 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.ul: 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.

Note:

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