9811,"sage exits with 0, even if it is unable to install a package.",drkirkby,GeorgSWeber,"I wanted to do some testing of Sage in a loop and would check the return code to see if what I used worked or not. But this is impossible, as Sage appears to exit with 0, even if it should not have. In the example below, I try to install a non-existent package using Sage. The return code in a case like this should be non-zero, but it is not.

The same happens if one uses {{{sage -i}}} to install a package. If it fails, the exit code is still 0.
In contrast, if I try this with a well written command like {{{ls}}}
{{{
drkirkby@hawk:~/sage-4.5.2$ ls some-non-existant-package
some-non-existant-package: No such file or directory
drkirkby@hawk:~/sage-4.5.2$ $?
bash: 2: command not found
}}}
the exit code is non-zero - in this case 2.

Also on a similar theme is #9799, showing that {{{make}}} can exit with the wrong code too.
