From: Gerrit Pape <[email protected]>
ENOSPC as a result of an echo builting failing gives no diagnostic.
Just as other shells, dash sets $? to 1, but aside from terminating
the script, this does not inform the user what the problem is:
zsh:
% echo foo > /dev/full
echo: write error: no space left on device
bash:
$ echo foo > /dev/full
bash: echo: write error: No space left on device
dash:
$ echo foo > /dev/full
[nothing]
Print an error to stderr like the other shells.
