Question

convert hh:mm:ss to seconds

Asked by: drewrockshard

Is there any one liner to convert hh:mm:ss to seconds.  In other words 01:20:50 (1:20 AM and 50 seconds) to just seconds?

It seems really simple -  however, I don't think the date command would work.  I don't want seconds from original Unix time - I actually want to know how many seconds are in 01:20:50.  This is obviously a sample time and will be different at any given time - so that's why I need a way to do this.  This would be a bash one-liner or sample code of the like.  I can implement into my script, so no need to create a whole base script for me (snippets welcomed).

How about a quick one-liner in perl?

perl -e '($h,$m,$s)=split(/:/,$ARGV[0]);print $h*3600+$m*60+$s, "\n";' 1:20:50

Is there a way without perl?  Ya, I could use it - however, I hate mixing languages like that.  Is there a way (function of some sort, etc) that I could do this in bash?
