I wondered if someone could point out the differences between the time commmand and usr/bin/time and the accuracy one might have over another.
Also, is there a website or two a person could maybe link for me to describe the differences?

9. UNIX for Dummies Questions & Answers
I have a filename 'INITIATE_FINAL_ALL_000080889.dat', and I want to capture just the number '80889' from it.
Here is what I have so far:
%> echo INITIATE_FINAL_ALL_000080889.dat | sed "s/*//g"
000080889
Now, I just need to trim off the padded zeroes.
