pfetch-rs
A rewrite of the pfetch system information tool by dylanaraps in Rust
About
If you are familiar with the pfetch system information tool by dylanaraps, this does the exact same thing, but with an about 10x faster runtime. pfetch is simple by design with some (but not many) configuration options and a minimalistic look.

Installation
Note: On openSUSE, install the rpm-devel
package for faster package count.
Binary
Download a binary from the latest release.
Cargo
cargo install pfetch
Homebrew
brew install pfetch-rs
AUR
Install the pfetch-rs or pfetch-rs-bin AUR package.
Performance
Benchmarks performed on an AMD Ryzen 5 3600. Execution time is measured using
hyperfine with -w 4 -m 500 -N
flags
Implementation | Mean [ms] | Min [ms] | Max [ms] |
---|---|---|---|
POSIX sh (bash) |
23.7 ± 0.9 | 22.3 | 29.3 |
POSIX sh (dash) |
15.9 ± 0.3 | 15.1 | 18.2 |
Rust (v2.3.0) | 2.2 ± 0.2 | 1.8 | 3.9 |
Note: This is with pacman
and flatpak
being the only installed package
managers. For more info, see Improving Performance.
Improving Performance
The by far slowest part of the pfetch
execution time is counting the installed
packages. For most package managers this is still very fast, but there are some
(currently nix
(and zypper
, if rpm-devel
is not installed)) that take
~500ms to report installed packages, which takes away all performance benefits
of the Rust version. If you have one or more of these installed, you can skip
counting them by setting the PF_FAST_PKG_COUNT
environment variable to any
value.
Configuration
Like the original pfetch
, pfetch-rs
is configured through environment
variables. Your existing config will probably still work, the only difference is
how padding is configured.
If you want to display a custom logo, you will have to download the source code,
make your changes to ./pfetch-extractor/logos.sh
and build the binary with
cargo b --release
