This question is somewhat related to another one on AskUbuntu, where OP asked how to decide which command to use ,
tail. So far, all the answers have focused on using either looping in bash or
time for single-shot runs. What bothers me about looping approach is that it introduces
bash's looping performance as overhead.
Are there ways to test commmand line utilities for performance without introducing shell's performance into the picture ? Are there ways other than
time to test performance ? In general, what else can be used to test command-line utilities ?
