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. shtml">manServer 1.07 from gcore.1 using doc macros.
