no ECHO, BOLD PROMPT etc in ./install script

[rmathar]

In the installation description there is an instruction to call ./install (with options...) in the local directory after untarring the iraf.tar.gz. However, there are no commands ECHO, BOLD, PROMPT etc used but not defined in that bin/sh, and just a ton of error messages on that fact is issued. There are some lower-case equivalent standard shell command in Linuxes, but not those misspelled once. I propose to define ECHO, BOLD and so on within the install shell script so the installation can proceed.

The ECHO, BOLD_ON etc. functions are defined in unix/hlib/util.sh and sourced in the install script:

iraf/install

Lines 37 to 39 in ba22d13

	if [ -e "$iraf/unix/hlib/util.sh" ]; then
	. "$iraf/unix/hlib/util.sh"
	fi

It is tested to work on both Linux and macOS, like here:

Could you specify you environment (Linux? macOS? Which version and distribution?), and which IRAF version you used? What is your /bin/sh?

Is this still a problem?

[rmathar]

No. I forgot to use a unset iraf before calling ./install -s.
A minor point is that the mkdir for the Local unix commands directory should have a switch -p to create non-existing directories.
