Bug in Documentation (Binary download)

[iocron]

It's interesting that this got unnoticed so far (tested on amazon linux, ubuntu). Based on the documentation https://www.parca.dev/docs/quickstart?environment=binary to download the agent (binary) you have to use the command below:

curl -sL https://github.com/parca-dev/parca-agent/releases/download/v0.40.2/parca-agent_0.40.2_`uname -s`_`uname -m` chmod +x ./parca-agent*

1. This won't download the file, the -o flag is missing
2. Potentially giving too much execute rights (chmod on ./parca-agent*) on all files that start with string "parca-agent..."
3. Always quote URLs
4. (optional) chmod u+x would be actually sufficient enough to run the command, since parca-agent needs to be started with root/sudo anyway

The corrected command (should usually work in all environments) would look like:

curl -o parca-agent -sL "https://github.com/parca-dev/parca-agent/releases/download/v0.40.2/parca-agent_0.40.2_$(uname -s)_$(uname -m)" && chmod u+x ./parca-agent

I'd like to add that for arm64 system this won't work even after this fix as uname -m says aarch64 particularly on my system, not arm64. There is no such binaries available for download.
