report which line of script we are at

This may have been discussed here but I'm not thinking of a good
string to find it with,
I wondered if a shell script can be made to report which line a
function that gets called is on.
I'm thinking of something like the perl code below that does that.
I use it to help debug scripts and in this case showing where in the
script this usage() function was invoked.
if(! $somevalue){
usage();
print "USAGE tripped at Line: <". __LINE__.">\n";
exit;
}
` __LINE__ ' carries the line number as value
Is there a handy way to do that in a shell script?
.
