You're right: $ time (echo `dircolors` > /dev/null) real 0m0.318s user 0m0.312s sys 0m0.008s I ran the previous tests with bash-3.1. With bash-3.2, echo `dircolors` take 0.088s of user time (1/4th of the time needed by bash-3.1), and dircolors > dircolors_output && sh ./dircolors_output still takes 0.004s, so it is more than 20 times faster than using command substitution. So, do you think that speeding up command substitution would be a difficult task? Regards, Nicolas
