Question 1

How to install up on Linux?

Accepted Answer

Download the binary from GitHub releases or use package managers: on ArchLinux, install via 'aur/up'; on FreeBSD, use 'pkg install up'; or on macOS, try 'brew install up', though support is unofficial.

Question 2

up vs Pipecut: which is better for building pipelines?

Accepted Answer

up offers a more interactive, terminal-based UI with instant preview and real-time feedback, while Pipecut is prior art with different features. up is actively developed for rapid iteration, but Pipecut might suit other workflows.

Question 3

How to save a pipeline in up?

Accepted Answer

After typing your pipeline in the input box, press Ctrl-X to exit and save the command to a file like up1.sh in the current directory. If the file exists, it increments the number up to 1000.

Question 4

Can up handle binary data or only text?

Accepted Answer

up is designed for text data exploration and boosts Linux text-processing utilities like grep and awk, so it may not handle binary data effectively. It's best for textual command output.

Question 5

Is up safe to use with dangerous commands like rm?

Accepted Answer

The README warns that using commands like 'rm' in up could be dangerous, as it executes pipelines interactively. Users should exercise the same caution as in a regular terminal to avoid data loss.

Question 6

How does up handle large or long-running inputs?

Accepted Answer

For long-running commands, up shows a tilde indicator and allows freezing the buffer with Ctrl-S to inject EOF, then unfreezing with Ctrl-Q. The 40 MB buffer limit may require splitting large datasets.
