Much of the code uses echo as way of returning results or a partial result in a pipe.
Other times echo is used as a logging mechanism, and inconsistently.
Here are two examples of the later:
uname_os_check.sh: echo "$0: uname_os_check: internal error '$(uname -s)' got converted to '$os' which is not a GOOS value. Please file bug at https://github.com/client9/shlib"
untar.sh: echo "Unknown archive format for ${tarball}"
Both also go to stdout, not stderr.
Better would be to have a function that does logging.
Thinking
log_error
log_info
log_debug
log_prefix
The last one would be a function that would emit a common prefix. A function so smart people could completely over-ride it and add a date or whatever, but by default it would be:
log_prefix() {
echo $0 or nothing ""
}
Also need some way of setting the level. Will need to see what syslog and friends do.
