gcore -- get core images of running process
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 com-
mand 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 4.2BSD.
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 tempo-
rarily stop the target process.
The gcore utility is not compatible with the original 4.2BSD version.
