/usr/bin/time: No such file or directory

Question

I'm trying to run the time command for a file on a virtual machine running Fedora 19 64-bit and I get the message "/usr/bin/time: No such file or directory". I tried googling, but it appears it's something that I should already have. How do I get this on my computer?

Answer 1

For those on a raspberry pi or similar debian-based distributions, I found that I could install the package time ( sudo apt install time ) to obtain access to the time command.

Edit: For Fedora-based systems, the package name might be different. Try a dnf search time , followed by a sudo dnf install {package_name} . I don't have a Fedora machine immediately to hand to get the exact package name from.

Answer 2

bash/zsh/modern shells usually implement a basic time command as a builtin. So it won't exist on the filesystem, but time mycommand should work.

If you want the "proper" time command (with more options eg: -l / -v ), then you'll need to install it via apt/yum/etc. You'll need to run it as /usr/bin/time mycommand so the shell-builtin doesn't get invoked.

Answer 3

It might be in other locations. I'd start by typing:

which time

This command will give you the path to time, if it's anywhere in your path.

If you need to build it yourself, you can get the source here:
