When doing a
tail -f error.log, how to insert programmatically a line break after nothing has been appened to the file for 3 seconds ?
(obviously, once one line break has been added, no other line break should be added until other line(s) of text is added to the log file)
For instance, these lines are appened to error.log :
foo bar boo [[wait 4 seconds]] 2far 2foo 2bar 2boo [[wait 40 seconds]] 2far
This would be the output in the console :
foo bar boo 2far 2foo 2bar 2boo 2far
