SYNOPSIS

gcore [-s] [-c core] [executable] pid

DESCRIPTION

The gcore utility creates a core image of the specified process, suitable for use with gdb(1). By default, the core is written to the file "core.<pid>". The process identifier, pid, must be given on the command line. If no executable image is specified, gcore will use "/proc/<pid>/file".

The following options are available:

-c Write the core file to the specified file instead of "core.<pid>".
-s Stop the process while gathering the core image, and resume it when done. This guarantees that the resulting core dump will be in a consistent state. The process is resumed even if it was already stopped. The same effect can be achieved manually with kill(1).

FILES

core.<pid> the core image
/proc/<pid>/file
the executable image

HISTORY

A gcore utility appeared in BSD 4.2 .

BUGS

Context switches or paging activity that occur while gcore is running may cause the program to become confused. For best results, use -s to temporarily stop the target process.

The gcore utility is not compatible with the original BSD 4.2 version.
