This is the third in our series of articles highlighting essential system tools. These are small utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities.
The first tools under the spotlight were ps_mem, a small utility that accurately reports memory consumption of software, and gtop, a system monitoring dashboard.
This time, we’ll take a look at pet, a simple command-line snippet manager. The software is written in the Go programming language.
A command-line interface allows the user to interact with the computer by typing in commands. The computer displays a prompt, the user keys in the command and presses enter or return.
These days I usually gravitate to installing software by compiling the source code. First clone the repository, and try to compile.
The make install failed on my system as my system was missing dep, a tool for managing dependencies for Go projects. The steps taken to install dep were:
go get github.com/golang/dep/cmd/dep
This creates a binary in /home/sde/golang/bin/. I also added the directory to the PATH environment.
Packages are available for popular Linux distributions including Debian, Ubuntu, RedHat, and others. For example, there’s a package available for pet in the Arch User Repository.
At a shell, typing ‘pet’ or ‘pet –help’ shows the available options.
For each snippet you can add a detailed description of what the command does, which acts as a useful aide-memoire.
Features of pet include:
- Register your command snippets easily using pet new.
- Easily edit snippet files.
- List all your snippets.
- Use variables (
<param=default_value>) in snippets.
- Search snippets interactively.
- Run snippets directly.
- Edit snippets easily (the snippets are managed in a TOML1 file).
- Sync and share snippets via Gist or GitLab Snippets automatically.
If you’re like me, you often forget useful commands, particularly ones with lots of flags. You can create aliases or use the history command combined with grep to alleviate this issue. But pet arguably offers a slicker way, as it lets you search the snippets to quickly find what you need.

1 TOML is a configuration file format that’s intended to be easy to read due to more obvious semantics which aims to be “minimal”.
