Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

Thank you so much Rudic!
It's almost okay. The only error is at here:
In barisprep code:
'a:1:{i:0;s:2:'" $2


How may I change it to:

Thank you

Hey c'mon, Baris, that should be easily doable by yourself, don't you think? You did similar things in your post #4.
# 10  
:/ Yes, I did before posting. This is my 2nd try:

Changed the part as:
'a:1:{i:0;s:2:'" \"$2\"

awk: 2: unexpected character '\'
awk: 3: unexpected character '''
awk: barisprep: line 3: runaway string constant "} ...

Also tried without escape:
'a:1:{i:0;s:2:'" "$2"

gives single quote:

Thank you

Did you look at what youdid in post #4? This a:1:{i:0;s:2:\"$COL2\";}" is close ... complete it with two unescaped double quotes.

FWIW - it seems to me you may not know about a shell facility called a here document.

It lets you write code that dynamically enters data for another program like mysql, and behaves as is if it was you directly typing into the program. What you are doing is temporarily replacing stdin with a shell script or an awk script, or a really complex set of statements, etc. The kind of thing data entry staff employees did 50 years ago.

Syntax: we are going to feed the program yesterday's date and last Friday's date, as a very simple example (uses linux/GNU date in the example)
/path/to/program  <<EOF   [ > /path/to/output file, write program stdout  from program to a file -- optional feature]
date -d yesterday
date -d "last friday"
# thanks to RudiC for finding the typo.

the <<EOF tells the shell to start feeding "keystrokes" to /path/to/program EOF is block name could be anything, Charlie or Baris or !
the EOF marks the end of the code block. This has to be in the LEFTMOST column
Most of what you asked for help with can be handled more easily with a here document.
