[Q-e-developers] Parsing wall time, bug with fixed width?

[Alin Marin Elena]

or a sed, bc solution which is space agnostic


[14:56:55 alin at abaddon:~]: echo "1h23m45.6s" | sed "s/h/*3600+/g;
s/m/*60+/g; s/s//g" | bc -l
5025.6
[14:57:09 alin at abaddon:~]: echo "1 h 23 m 45.6 s" | sed "s/h/*3600+/g;
s/m/*60+/g; s/s//g" | bc -l
5025.6

regards,
Alin
