[File] Change mime-type of OpenRC script to text/x-shellscript

[Edin Tarić]

Hi there,

The OpenRC service scripts are essentially shell scripts and since there are text editors that rely on 'file' to perform correct syntax highlighting, it would be great if the mime-type can be adjusted to reflect that. :)

OpenRC scripts can be recognized by this shebang:
#!/sbin/openrc-run

'file' currently recognizes it as "a /sbin/openrc-run script, ASCII text executable" with a mime-type of text/plain.

Thanks in advance!

Best,
Edin
