AIX automation

OK,

according to what I know from the previous Q:

-- Initialization and first step:
 

#!/bin/ksh
STEP="CAT I Remediation"
echo "You are about to start $STEP, would you like to continue? Enter yes or no."
read A; if ! echo $A | grep  -E -q "Yes|yes" ; then exit; fi
echo "Starting $STEP"

STEP="Store SSH Keys"
echo "You are about to start $STEP, would you like to continue? Enter yes or no."
read A; if ! echo $A | grep  -E -q "Yes|yes" ; then exit; fi
echo "Starting $STEP"

./maint/6100-01-03/save_sshkeys.ksh

if [[ $? -eq 0 ]]; then
   echo "$STEP succeeded"
     else echo "$STEP failed"
fi

-- Now for ssl/ssh
 

STEP="Install SSH"
echo "You are about to start $STEP, would you like to continue? Enter yes or no."

-- Finito.

Tickers or in-progress indicators are hard to implement in ksh.
It can be done by running the single steps in background and "ticking" while checking for existence of the backgroubd PID. But this is just too error-prone to do it just for fun. Is it really necessary?

Next, some hints to make the output look nice (?)

Just bolding:

BOLD=$(tput smso)
UNBOLD=$(tput rmso)

echo ${BOLD}SSH Keys are stored.${UNBOLD}

You can also use underlines. Bolding and underlining can be done with one attribute called "sgr", where:
All off:  
sgr 0 0
Underline on, bold off:
sgr 0 1
Both on:
sgr 1 1
Underline off, bold on:
sgr 1 0

So to underline and bold in one go:

BU=$(tput sgr 1 1)
NOBU=$(tput sgr 0 0)

echo ${BU}SSH Keys are stored.${NOBU}

And finally, if all errors shall go to an errorlog in /tmp:

Add as line 2 of the script, just after "#!/bin/ksh":

exec 2>/tmp/errorlog

Discarding stdout of the installp steps is already implemented.
