gcore - Generate a core file of a running program
gcore [-a] [-o prefix
Generate core dumps of one or more running programs with process IDs
, etc. A core file produced by gcore
is equivalent to one produced by the kernel when the process crashes
(and when "ulimit -c"
was used to set up an appropriate core dump
limit). However, unlike after a crash, after gcore
its job the program remains running without any change.
Dump all memory mappings. The actual effect of this option depends on
the Operating System. On GNU/Linux, it will disable
- -o prefix
The optional argument prefix specifies the prefix to be used
when composing the file names of the core dumps. The file name is
composed as prefix.pid, where pid is the
process ID of the running program being analyzed by gcore.
If not specified, prefix defaults to gcore.
The full documentation for GDB
is maintained as a Texinfo manual.
If the "info"
programs and GDB
documentation are properly installed at your site, the command
should give you access to the complete manual.
