time not accepting arguments
I installed time but when I use it, I am getting the portable format, not the default format. When installed I think it said GNU time 1.7 or 1.72.
Commands like
time --help
time --version
fail with the error "command not found". The TIME environment variable is unset. Why is time behaving like this?

timeis a shell keyword, you probably have to point to the full path of the installed time to use it:/usr/bin/time --versionor maybe alias it.

Is it possible you already have an alias fortime='time -p'that would explain the portable format?

@Jesse_b no alias. I think it is using the bash keyword 'time' which apparently is identical to time -p

On my system the time builtin still has a-poption to print portable.

When looking for a command the shell uses the following preference:
- aliases
- Parameter expansion, command substitution, arithmetic expansion, and quote removal before being assigned to the variable
- functions
- BUILTIN commands
- HASH table
- Search
PATH
So the time keyword will be used with preference over the installed version of time presumably found in your PATH. You can overcome this with an alias.

While Jesse_b is correct about how shells generally look up commands, there's an easier fix.
time --version
Bash, ksh, zsh, and I believe a few other common shells will treat a leading backslash on a command with no path as 'skip to looking into the PATH for this thing.'
Also, knowing what the time builtin is, we could also get around this by running
time time --version
After all, the reason for the command not found error rather than a no such option error is because the shell builtin just runs the command that follows and checks how long it took to run when it finishes... which is the same thing that /bin/time does.
If you're expecting time to take arguments... are you wanting to find out what time it is? Because that's the date command.
