I am looking for a command that will
accept (as input) multiple lines of text, each line containing a single integer, and
output the sum of these integers.
As a bit of
background, I have a log file which includes timing measurements. Through grepping for
the relevant lines and a bit of sed
reformatting I can list all
of the timings in that file. I would like to work out the total. I can pipe this
intermediate output to any command in order to do the final sum. I have always used
expr
in the past, but unless it runs in RPN mode I do not think
it is going to cope with this (and even then it would be
tricky).
How can I get the summation of
integers?
