I track the output of large builds by running the make/configure etc from within an emacs shell
Sometimes the build is so large that I also want to track how long it takes (while I go do something else not necessarily on the computer)
So I do something like
date
make
date
in the emacs eshell. ie I type the second date when the make starts
However I dont see its output (maybe lost somewhere in the make output??)
Any ideas?
