144 .IX Header "SYNOPSIS"
145 gcore [\-o \fIfilename\fR] \fIpid\fR
147 .IX Header "DESCRIPTION"
148 Generate a core dump of a running program with process \s-1ID \s0\fIpid\fR.
149 Produced file is equivalent to a kernel produced core file as if the process
150 crashed (and if \f(CW\*(C`ulimit \-c\*(C'\fR were used to set up an appropriate core dump
151 limit). Unlike after a crash, after \fBgcore\fR the program remains
152 running without any change.
155 .IP "\fB\-o\fR \fIfilename\fR" 4
156 .IX Item "-o filename"
157 The optional argument
158 \&\fIfilename\fR specifies the file name where to put the core dump.
159 If not specified, the file name defaults to \fIcore.\fIpid\fI\fR,
160 where \fIpid\fR is the running program process \s-1ID.\s0
