set debug [<level>]
When turned on, this variable enables various degrees of debugging while the client is running. It is useful for seeing precisely where a particular alias or function is failing, what variables are being assigned what values, etc. There are three general classes of debug output, each assigned a unique number.
| Bit | Value | Purpose |
|---|---|---|
| 0 | 1 | displays all commands executed, including aliases |
| 1 | 2 | displays all actual alias and variable substitutions |
| 2 | 4 | displays all function calls and their return values |
Multiple classes may be displayed at once by adding the desired values together. A setting of 0 (zero) turns off debugging.
To show all commands executed and alias expansion:
/set debug 3
To show everything:
/set debug 7
This command can generate a lot of output, so setting HOLD_MODE on is recommended.
