| <!-- man end --> |
| </pre> |
| <!-- man begin DESCRIPTION gcore --> |
| <p>Generate core dumps of one or more running programs with process IDs |
| <var>pid1</var>, <var>pid2</var>, etc. A core file produced by <samp><span class="command">gcore</span></samp> |
| is equivalent to one produced by the kernel when the process crashes |
| (and when <kbd>ulimit -c</kbd> was used to set up an appropriate core dump |
| limit). However, unlike after a crash, after <samp><span class="command">gcore</span></samp> finishes |
| its job the program remains running without any change. |

| <dt><samp><span class="env">-a</span></samp><dd>Dump all memory mappings. The actual effect of this option depends on |
| the Operating System. On <span class="sc">gnu</span>/Linux, it will disable |
| <code>use-coredump-filter</code> (see <a href="set-use_002dcoredump_002dfilter.html#set-use_002dcoredump_002dfilter">set use-coredump-filter</a>) and |
| enable <code>dump-excluded-mappings</code> (see <a href="set-dump_002dexcluded_002dmappings.html#set-dump_002dexcluded_002dmappings">set dump-excluded-mappings</a>). |
| |
| <br><dt><samp><span class="env">-o </span><var>prefix</var></samp><dd>The optional argument <var>prefix</var> specifies the prefix to be used |
| when composing the file names of the core dumps. The file name is |
| composed as <samp><var>prefix</var><span class="file">.</span><var>pid</var></samp>, where <var>pid</var> is the |
| process ID of the running program being analyzed by <samp><span class="command">gcore</span></samp>. |
| If not specified, <var>prefix</var> defaults to <var>gcore</var>. |
