77	2022-08-23 09:33:58	12715	to previous	emanuele6	simplify awk (the environment variables are always set, and even if they weren't it would not be a problem)	view
76	2022-08-21 21:43:48	12727	to previous	emanuele6	fixup variable names	view
75	2022-08-21 21:38:10	12724	to previous	emanuele6	pass variables to awk using environment variables instead of -v var="${var//'\'/'\\'}". it seems that nawk doesn't like strings containing newline as argument for -v, so that pe is not good enough	view
