After that, you can run Lintian on a changes file or any Debian binary, udeb or source packages like this:
$ lintian libc5_5.4.38-1.deb W: libc5: old-fsf-address-in-copyright-file W: libc5: shlib-without-dependency-information usr/lib/libgnumalloc.so.5.4.38 W: libc5: shlib-without-dependency-information lib/libc.so.5.4.38 W: libc5: shlib-without-dependency-information lib/libm.so.5.0.9 E: libc5: shlib-with-executable-bit lib/libc.so.5.4.38 0755 E: libc5: shlib-with-executable-bit lib/libm.so.5.0.9 0755 E: libc5: shlib-missing-in-control-file libgnumalloc usr/lib/libgnumalloc.so.5.4.38 $
Please note that some checks are cross-package checks and can only be (accurately) performed if the binary packages and the source are processed together. If Lintian is passed a changes file, it will attempt to process all packages listed in the changes file.
Lintian supports a number of command line options, which are documented in the manpage of lintian(1). Some of the options may appear in the lintianrc file (without the leading dashes) in Lintian 2.5.1 (or newer).
