time in Ubuntu

我的Ubuntu 8.04上有兩個time

/usr/bin/time是屬於GNU的time package

test@test-laptop:~$ /usr/bin/time --version
GNU time 1.7test@test-laptop:~$ dpkg -S /usr/bin/time
time: /usr/bin/time
test@test-laptop:~$ dpkg -S /usr/bin/time
time: /usr/bin/time

這個則應該是bash builtin的time

test@test-laptop:~$ time --version
bash: --version: command not found

real 0m0.168s
user 0m0.132s
sys 0m0.036s
test@test-laptop:~$
