gcore(1)


NAME

   gcore - Generate a core file of a running program

SYNOPSIS

   gcore [-o filename] pid

DESCRIPTION

   Generate a core dump of a running program with process ID pid.
   Produced file is equivalent to a kernel produced core file as if the
   process crashed (and if "ulimit -c" were used to set up an appropriate
   core dump limit).  Unlike after a crash, after gcore the program
   remains running without any change.

OPTIONS

   -o filename
       The optional argument filename specifies the file name where to put
       the core dump.  If not specified, the file name defaults to
       core.pid, where pid is the running program process ID.

SEE ALSO

   The full documentation for GDB is maintained as a Texinfo manual.  If
   the "info" and "gdb" programs and GDB's Texinfo documentation are
   properly installed at your site, the command

           info gdb

   should give you access to the complete manual.

Opportunity


Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.



Free Software


Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.



Free Books


The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.



Education


Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
