Zsh has an ingenious feature that automatically prints timing statistics for commands taking longer than $REPORTTIME
to execute. Think of it as automatically executing a pipeline through time
as needed.
From the Zsh Manual:
REPORTTIME
If nonzero, commands whose combined user and system execution times
(measured in seconds) are greater than this value have timing statistics
printed for them.
Does there exist a similar feature, or set of scripts that enables similar behaviour, for Bash?
preexec
