I have recently noticed that my Ubuntu system has been slowly filling up a file called ~/core
-rw------- 1 tom tom 2.4G Feb 1 18:08 core
It has recently reached 2.4G in size.
It contains many lines like this:
��9��6����6�I��6�Cu���~I:��e���x86_64/snap/pycharm-professional/179/jbr/bin/java-classpath/snap/pycharm-professional/179/lib/bootstrap.jar:/snap/pycharm-professional/179/lib/extensions.jar:/snap/pycharm-professional/179/lib/util.jar:/snap/pycharm-professional/179/lib/jdom.jar:/snap/pycharm-professional/179/lib/log4j.jar:/snap/pycharm-professional/179/lib/trove4j.jar:/snap/pycharm-professional/179/lib/jna.jar-Xms128m-Xmx1995m-XX:ReservedCodeCacheSize=240m-XX:+UseConcMarkSweepGC-XX:SoftRefLRUPolicyMSPerMB=50-ea-XX:CICompilerCount=2-Dsun.io.useCanonPrefixCache=false-Djava.net.preferIPv4Stack=true-Djdk.http.auth.tunneling.disabledSchemes=""-XX:+HeapDumpOnOutOfMemoryError-XX:-OmitStackTraceInFastThrow-Djdk.attach.allowAttachSelf=true-Dkotlinx.coroutines.debug=off-
I can't seem to find any information about this file online.
Is it safe to delete this file or symlink it to /dev/null?
file ~/coreand/orgdb -c ~/core. See for example A big core dump appeared in my home folder - what is it and how can I delete it? – steeldriver Feb 01 '20 at 16:06
