Name

       nix-store --read-log - print build log

Synopsis

       nix-store {--read-log | -l} paths…

Description

       The  operation --read-log prints the build log of the specified store paths on standard output. The build
       log is whatever the builder of a derivation wrote to standard output and standard error. If a store  path
       is not a derivation, the deriver of the store path is used.

       Build  logs  are  kept  in  /nix/var/log/nix/drvs.  However,  there  is  no guarantee that a build log is
       available for any particular store path.  For instance, if the path was downloaded as a pre-built  binary
       through a substitute, then the log is unavailable.
