How do I avoid getting large core files?
You can see and change your core file size limit and other limits. The command will depend on the shell you use.
If you use tcsh, then the "limit" command gives the info:
==> limit cputime unlimited filesize 50000 kbytes datasize unlimited stacksize 8192 kbytes coredumpsize 1000000 kbytes memoryuse unlimited descriptors 1024 memorylocked unlimited maxproc 256 openfiles 1024To eliminate core files, give the command
==> limit coredumpsize 0You can put this command in your .cshrc start-up file so that it takes effect in every shell.
If you use bash, then the corresponding command is "ulimit -a" (the "-a" is for "all").
[furnstah@ntg4004 furnstah]$ ulimit -a core file size (blocks) 1000000 data seg size (kbytes) unlimited file size (blocks) 50000 max memory size (kbytes) unlimited stack size (kbytes) 8192 cpu time (seconds) unlimited max user processes 256 pipe size (512 bytes) 8 open files 1024 virtual memory (kbytes) 2105343To eliminate core files, give the command
[furnstah@ntg4004 furnstah]$ ulimit -c 0You can put this command in one of your .bashrc start-up file so that it takes effect in every shell.
