difference between \/opt and \/usr\/local<\/strong><\/span><\/h4>\n
    \n
  • The basic difference is that \/usr\/local is for software not managed by the system packager, but still following the standard unix deployment rules.<\/li>\n
  • That’s why you have \/usr\/local\/bin, \/usr\/local\/sbin \/usr\/local\/include etc…<\/li>\n
  • \/opt is for software that doesn’t follow this and is deployed in a monolithic fashion. This usually includes commercial and\/or cross-platform software that is packaged in the “Windows” style.<\/li>\n
  • \/usr\/local\/ usually contains a bin, sbin, lib, and so forth, so works for small scripts, libraries, and the like while \/opt\/ tends to accumulate applications that’ve grown large enough to accumulate their own directory tree.<\/li>\n
  • \/usr\/local, for self, inhouse, compiled and maintained software. \/opt is for non-self, external, prepackaged binary\/application bundle installation area.<\/li>\n
  • \/opt is for third-party applications that don’t rely on any dependencies outside the scope of said package. \/usr\/local is for packages installed on this machine outside the scope of the distribution package manager.<\/li>\n<\/ul>\n

    An example:<\/strong><\/span><\/h4>\n
      \n
    • An open source sip-client supplied as a .deb would install into \/usr. If it was built with the Qt framework, apt would pull it in as a dependency.<\/li>\n
    • The same open source sip-client built from source would reside in \/usr\/local so it would not be messed up by apt if you later installed a .deb package for the same application. You could either build its dependencies from source, or get them from the package manager.<\/li>\n
    • A third-party application in \/opt is supposed to be self-contained. For instance, a proprietary sip-client using Qt would not rely on the version from apt, but would have it bundled or statically linked in.<\/li>\n<\/ul>\n[ad type=”banner”]\n","protected":false},"excerpt":{"rendered":"
