I keep getting the response 130; obviously an error. Where can i find a
list of error codes on linux?
Unfortunately there is no such thing. Exit code 0 for success, non-0
for failure. Some programs have documented exit codes other than 0
and 1.
Here is some information from the BASH man.page:
EXIT STATUS
For the shell's purposes, a command which exits with a zero exit status
has succeeded. An exit status of zero indicates success. A non-zero
exit status indicates failure. When a command terminates on a fatal
signal N, bash uses the value of 128+N as the exit status.
This would indicate that your program terminated on a fatal signal 2,
since 128+2 = 130.
From "man 7 signal":
SIGINT 2 Term Interrupt from keyboard
Interrupt from keyboard is what normally happens when you type <ctrl> C.
If this isn't what happened, and you wrote the program yourself, maybe
it doesn't have a proper exit() statement. Or somebody else wrote it
without a proper exit() statement.
