How To Find Library Version On Linux Mac Unix by Command line

November 17th, 2011 by Regaz



If you need to find Version Info about the Libraries associated to a Package on Mac

Take the Time of Reading and Understanding to Get a Clear Insight

  1. You perform from Terminal the following Commands:
    otool -L /path/To/Your/bin/Package

    In the Output you find a List of Libraries Associated with the Relative Version.
    Example:

    otool -L /usr/local/bin/curl

    Output:

    /usr/local/bin/curl:
    /usr/local/lib/libcurl.4.dylib (compatibility version 7.0.0, current version 7.0.0)
    /System/Library/Frameworks/LDAP.framework/Versions/A/LDAP (compatibility version 1.0.0, current version 2.2.0)
    /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3)
    /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.7)

    So if you need only to know Which is the Library Version before you need to find an Associated Package…
    On Unix and Linux you can Use Instead the ldd Command.

    ldd /path/To/Your/bin/Package
