I am releasing a multi-platform application. It will potentially be released on Windows, OSX, and Linux distributions.
Users expect to install it wherever they like, so it will not be a package like RPM. It will be a simple archive file.
I plan to put the platform name in the name of the downloadable file, like:
myapp-0.6.3-osname.tgz
While I could use anything for osname, I would like to follow whatever standard there is.
Is there a standard?
I've no idea if there is a standard. Here's Java's current naming convention for JDK SE 8u45, and it seems pretty good to me:
Product / File Description File Size Download
------------------------------------------------------------------------------------
Linux x86 146.89 MB jdk-8u45-linux-i586.rpm
Linux x86 166.88 MB jdk-8u45-linux-i586.tar.gz
Linux x64 145.19 MB jdk-8u45-linux-x64.rpm
Linux x64 165.24 MB jdk-8u45-linux-x64.tar.gz
Mac OS X x64 221.98 MB jdk-8u45-macosx-x64.dmg
Solaris SPARC 64-bit (SVR4 package) 131.73 MB jdk-8u45-solaris-sparcv9.tar.Z
Solaris SPARC 64-bit 92.9 MB jdk-8u45-solaris-sparcv9.tar.gz
Solaris x64 (SVR4 package) 139.51 MB jdk-8u45-solaris-x64.tar.Z
Solaris x64 95.88 MB jdk-8u45-solaris-x64.tar.gz
Windows x86 175.98 MB jdk-8u45-windows-i586.exe
Windows x64 180.44 MB jdk-8u45-windows-x64.exe
So the convention is basically {appname}-{version}-{OS}-{architecture}.{extension}.
