You can adjust it as needed and as for why I have --insecure flag, I have a direct network cable between my PC to the server, so encryption or HTTPS is not needed here. This is probably my favorite command, because I would write above as .sra.sh in home directory and then alias the .bashrc to make a sra command by adding alias sra=/home/{your user account}/.sra.sh in .bashrc and from there, anytime I have an interesting repository that I want to archive, I simply run sra {git url} and that’s it. It also specify the mirror interval manually for 3 days interval rather than every 8 hours that would’ve needlessly spam the git server.

This is something I rely on everyday both as developer and system admin, I would maintain a different supply chain and prevent a supply chain attacks by generating my own package feeds/registry automatically from Gitea/Forgejo.

Edited to Add: I noticed this community is Powershell, here the powershell version of above:

param (
    [Parameter(Mandatory=$true)]
    [string]$gitRepoUrl
)

function Test-Url($url) {
    $regex = "(https?|ftp|file)://[-[:alnum:]\+&@#/%?=~_|!:,.;]*[-[:alnum:]\+&@#/%=~_|]"
    return $url -match $regex
}


$basename = Split-Path $gitRepoUrl -Leaf
$reponame = [System.IO.Path]::GetFileNameWithoutExtension($basename)
