| // Make sure manually escaped pipes are handled properly by the shell. |
| // Specifically, we want to make sure that if we escape a pipe after %{exec}, |
| // it gets executed by the %{exec} substitution, as opposed to the result of |
| // the %{exec} substitution being piped into the following command. |
| // |
| // This is a bit tricky to test. To test this, we basically want to ensure |
| // that both sides of the pipe are executed inside %{exec}. When we're inside |
| // %{exec}, the one difference we can rely on is that we're in a temporary |
| // directory with all file dependencies satisfied, so that's what we use. |

| // RUN: touch %t.foobar |
| // RUN: %{exec} echo \| ls > %t.out |
| // RUN: grep -e ".foobar" %t.out |
