Binary package hint: time
I was trying to use the 'time' command today to get execution time from a few different programs. It seems to work just fine so long as you just invoke it as 'time COMMAND COMMAND-ARGS'... however I wanted to get more verbose output, and eventually output to a file. From the 'time' man page:
--------------------------------------
-o FILE, --output=FILE
Write the resource use statistics to FILE instead of to the
standard error stream. By default, this overwrites the file,
destroying the file's previous contents. This option is useful
for collecting information on interactive programs and programs
that produce output on the standard error stream.
--------------------------------------
and....
--------------------------------------
-v, --verbose
Use the built-in verbose format, which displays each available
piece of information on the program's resource use on its own
line, with an English description of its meaning.
--------------------------------------
so... I tried calling 'time' first like so: "time -v octave test.m"
which returns:
--------------------------------------
-v: command not found
real 0m0.989s
user 0m0.190s
sys 0m0.070s
--------------------------------------
I also tried the long version:
--------------------------------------
$ time --verbose octave test.m
--verbose: command not found
real 0m0.200s
user 0m0.150s
sys 0m0.060s
--------------------------------------
what??? even the version command doesnt work:
--------------------------------------
$ time --version
--version: command not found
real 0m0.202s
user 0m0.170s
sys 0m0.040s
--------------------------------------
This is a significant issue for my project, since I need to output timing data for a lot of different commands, and I really dont want to copy-paste them all manually from the terminal, and redirecting the error stream (for time's info) isnt an option because I need to collect the program output as well, and it would be significantly difficult to extract the timing data from those files after the fact.

I was able to reproduce the issue with xubuntu 10.04
In fact an adapted example from the man page:
time -a -o log ls -l
does not seem to work
autif@xu:~$ time -a -o log ls -l
-a: command not found
