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.

1025,HOST1     15533-rdp2     
 1025,COMMENT   # RDP-Terminal 2

Don't forget to reset your IFS afterwards.


EDIT: or, even better to get HOST1 and 2 in the right order:

Code:
echo "${!ENTRIES[*]}" | sort -t, -k1,1n -k2,2.2r -k2.3 | while read IX; do printf "%-15s%-15s\n" $IX ${ENTRIES[$IX]}; done

Your method is not working, this is what i get back
Code:
414,IP         205,HOST1
205,HOST2      414,COMMENT
505,HOST2      505,IP
505,HOST1      1025,COMMENT
775,COMMENT    1015,IP
1025,IP        775,IP
505,COMMENT    205,COMMENT
410,IP         775,HOST1
1015,HOST2     1015,HOST1
775,HOST2      410,HOST1
1015,COMMENT   410,HOST2
414,HOST1      414,HOST2
1025,HOST2     1025,HOST1
410,COMMENT    205,IP

This methode from nezabudka even works better. this sorts my array correct
Code:
shuf -e ${!ENTRIES[@]} | sort -V | while read d; do echo $d=${ENTRIES[$d]}; done

my only problem is now how to get the this entrys in this output order
Code:
# IP - HOST1  - HOST2 - COMMENT

# 9  
Did you set the IFS variable as indicated?
Try the sort keys given with netzabudka's proposal as well.

Oh it was my fault. Its working of course as well. Thank you

So know i dont understand (my bash skills are very low) how to get this in a file line by line in this format
Code:
# IP - HOST1  - HOST2 - COMMENT

Like this
Code:
10.155.33.20              unas15533              unas      # Comment
10.155.33.101             15533-rdp1             rdp1      # Comment
10.155.33.102             15533-rdp2             rdp2      # Comment

I know how to create the file and how to write in it but i dont understand how i can use your funtion to geht this
# 11  
Try paste:
Code:
echo "${!ENTRIES[*]}" | sort -t, -k1,1n -k2,2.2r -k2.3 | while read IX; do printf "%s\n" ${ENTRIES[$IX]}; done | paste -sd"\t\t\t\n"
111.122.133.20     unas15533     unas    # UNAS
111.122.133.77     15533-wlan    wlan    # WLAN Access Point
111.122.133.101    15533-rdp1    rdp1    # RDP-Terminal 1
111.122.133.102    15533-rdp2    rdp2    # RDP-Terminal 2

Aside: How did you create those arrays? Mayhap all this messing around could be avoided, and your output correctly computed in the first place?

Code:

--- Post updated at 14:02 ---

And so it works
sort -t, -k1,1n -k2,2.2r

Thank you so much

This works perfect for me:
Code:
IFS=$'\n'
echo "${!ENTRIES[*]}" | sort -t, -k1,1n -k2,2.2r -k2.3 | while read IX; do printf "%-20s\n" ${ENTRIES[$IX]}; done | paste -sd"\t\t\t\n"
