Re: How do i figure out what exit code 13 means?

[Alex Mantel]

Hello Paul,

thank you for your input. I used strace and found out, that I 
accidentally closed stderr manually. My provided sample did not 
sufficient represent the problem.

Using strace as you said, showed a pipe error ("-1 EPIPE (Broken 
pipe)"). Which indicated that something was wrong with stderr. You can 
inspect the line below:

```
read(0, "", 10184)                      = 0
write(2, "tar: ", 5)                    = -1 EPIPE (Broken pipe)
--- SIGPIPE {si_signo=SIGPIPE, si_code=SI_USER, si_pid=78098, 
si_uid=103} ---
+++ killed by SIGPIPE +++
````

However, it didn't explain why the return code was 13 after removing the 
manual close on stderr Especially because it seems that the program has 
been 'killed'.

Thank you! Regards, Alex
