Re: Capture Exit Code Using Pipe & Tee

The exit value is always 0, because it's returning the tee value, and not make. Any and all help is very apprciated.

Not quite. It's returning the error code of the shell invoked to execute the command. system sometimes, but not always, passes the command to /bin/sh. This is one of those times. See the docs for details.

Both true and ~~untrue~~ misleading(?). It's getting the return/error code of the shell, yes. However, the shell is getting it from the tee command. If tee were to return 1, the shell would return 1, regardless of what make did. merlyn's answer is definitely the right track. Doing this in perl is actually not that bad, and though it may take more code than shmem's response, I'm not sure it'd be less readable ;-)	[reply]

No, it doesn't necessarily get it from the `tee` command, and it always gets it from the shell when the it is called. I can think of three circumstances where it does not. If the shell can't execute `tee`, the error code would not be that of `tee`. If the shell exits due to a signal or a core dump, the error code would not be that of `tee`. (Right?) If the script runs under Windows and `tee` returns an error code greater than 1, the error code returned would be 1.	[reply] [d/l] [select]
