@ -29,4 +29,6 @@ The following options are available:
- `-D` or `--debug-stack-frames=DEBUG_LEVEL` specify how many stack frames to display when debug messages are written. The default is zero. A value of 3 or 4 is usually sufficient to gain insight into how a given debug call was reached but you can specify a value up to 128.
- `-f` or `--features=FEATURES` enables one or more feature flags (separated by a comma). These are how fish stages changes that might break scripts.
The fish exit status is generally the exit status of the last foreground command. If fish is exiting because of a parse error, the exit status is 127.
