Question 1

How do I use sig to monitor Kubernetes logs?

Accepted Answer

Pipe the output of tools like stern to sig, e.g., 'stern --context kind-kind etcd |& sig'. Use the --cmd option to enable command retry for re-evaluating past data, as shown in the examples.

Question 2

sig vs grep for live log filtering?

Accepted Answer

Sig is interactive and updates in real-time as you type, ideal for streaming data, while traditional grep is better for batch processing static files. Sig adds features like pause/resume and archived modes for flexibility.

Question 3

How to customize keybindings in sig?

Accepted Answer

Edit the config.toml file to define custom keybinds for actions like exit, retry, and navigation, as detailed in the configuration section of the README with examples for streaming and archived modes.

Question 4

Can sig handle multi-line log entries?

Accepted Answer

The README does not specify multi-line support; sig appears designed for line-based streaming, so it might not be ideal for logs that span multiple lines without preprocessing.

Question 5

What's the difference between sig and ugrep?

Accepted Answer

Sig focuses on real-time interactive grep for streaming, with features like command retry and archived mode. Ugrep offers more advanced regex options and static file handling, but sig's archived mode is similar to ugrep's -Q for interactive search.

Question 6

Is sig available for Windows?

Accepted Answer

Installation methods listed are primarily for Unix-like systems (Homebrew, Cargo, Arch Linux, Nix). Windows support might require building from source via Cargo, which could be less straightforward than native package managers.
