Hello Some feedback on this page https://man7.org/linux/man-pages/man5/core.5.html 1) "disk file" sounds rather old fashioned, usually would just say "file", on this page, removing the word "disk" "The default action of certain signals is to cause a process to terminate and produce a /core dump file/, a disk file containing an" 2) We wouldn't regularly say "nonwritable" in English, "not writeable" is better English 3) Could i ask to clarify my understanding. For this "The binary being executed by the process does not have read permission enabled." -- is this when the binary permissions are changed after it starts running? I thought a core file was just a dump from RAM, does it really even need to open the ELF file again? 4) I noticed %P always gave me P1200 even after a reboot I recall, I had expected it be '1', do you see similar?
