I want to time reading bash history and put the result into a variable.
time (which is a shell keyword) prints the result to
stderr, and apparently redirecting
stderr from shell keywords doesn't work the same as redirecting regular command output. In other words,
foo=$(time history -r 2>&1)
doesn't work (
foo variable is empty, output is printed to terminal). How can I capture the output of
history is a shell builtin, I cannot use external
time command (i.e.
/usr/bin/time) - I have to use
time keyword in bash.
