Temporary File Hosting with 0x0.st

Sometimes you need a quick way to upload and share temporary files, like logs, for troubleshooting. 0x0.st is a simple and open-source solution that

• Upload files for free
• Keep them at least 30 days (which should be more than enough for most cases)
• Has an API for you to use.

How I use it

I wrote a small script to upload files or data directly to 0x0.st. Here’s the script:

#!/bin/env bash

# Check if the script is receiving input from a pipe
if [ -p /dev/stdin ]; then
    curl -sS -F "file=@-" https://0x0.st | tee >(xclip -selection clipboard)
# Check if a file argument is provided
elif [[ -n "$1" && -f "$1" ]]; then
    curl -sS -F "file=@$1" https://0x0.st | tee >(xclip -selection clipboard)
else
    echo "Usage: $0 <file> or pipe data to the script"
    exit 1
fi

How it works is that it detects input: checks if data comes from a pipe or a provided file & send them over to 0x0.st. The script then print the upload URL & copy the URL to clipboard. You need curl, tee & xclip for this to work.

Example usage

To upload logs or other output, you can pipe data like this:

journalctl -u foo | upload_0x0

Or upload a file:

upload_0x0 somefile.log

This generates a URL you can share with others for troubleshooting. Simple and effective!
