A comment on A disk so full, it couldn't be restored. Parent comment

That seems to be zsh-specific syntax that is like ">" except that overrides a CLOBBER setting[1].

However, it won't work in bash. It will create file named "!" with the same contents as "filename". It is equivalent to "cat /dev/null filename > !". (Bash lets you put the redirection almost anywhere, including between one argument and another.)

Yikes, then I have remembered wrong about bash, thank you.

In that case I'll just always use `truncate -s0` then. Safest option to remember without having to carry around context about which shell is running the script, it seems.
