If the return value of a command is greater than 128, it means that the command is terminated by signal.<\/p>\n
$ man bash<\/pre>\nThe return value of a simple command is its exit status, or 128+n if the command is terminated by signal n.\r\n<\/pre>\nExample:<\/p>\n
$ some_command\r\n$ echo $?\r\n139\r\n<\/pre>\nIn the above example, the return value is 139. Because 139=128+11 it means that the command was terminated by signal 11.
\nSee `man signal` and you will find that signal 11 is SIGSEGV and it means segmentation violation.<\/p>\n","protected":false},"excerpt":{"rendered":"
