Examining Core Files

The proc tools enable you to examine process core files, as well as live processes. The proc tools are utilities that can manipulate features of the /proc file system.

The /usr/proc/bin/pstack, pmap, pldd, pflags, and pcred tools can be applied to core files by specifying the name of the core file on the command line, similar to the way you specify a process ID to these commands.

For more information about using proc tools to examine core files, see proc(1).
