CID2  --- TYP2 --- DCN2 --- INDATE2 --- IN-DATA2
CID3  --- TYP1 --- DCN3 --- INDATE3 --- IN-DATA3
CID4  --- TYP1 --- DCN4 --- INDATE4 --- IN-DATA4
CID5  --- TYP1 --- DCN5 --- INDATE5 --- IN-DATA5

Input File2 

CID2  --- TYP2 --- DCN2 --- OUTDATE2 --- OUT-DATA2
CID3  --- TYP1 --- DCN3 --- OUTDATE3 --- OUT-DATA3
CID1  --- TYP1 --- DCN1 --- OUTDATE1 --- OUT-DATA1
CID4  --- TYP1 --- DCN4 --- OUTDATE4 --- OUT-DATA4
CID5  --- TYP1 --- DCN5 --- OUTDATE5 --- OUT-DATA5

Expected output
----------------
CID: CID1
DCN: DCN1
Type: TYP1
INDATE1: Req data: IN-DATA1
OUTDATE1: resp data: OUT-DATA1
-----------------
CID: CID2
DCN: DCN2
Type: TYP2
INDATE2: Req data: IN-DATA2
OUTDATE2: resp data: OUT-DATA2
-------------------
CID ID: CID3
DCN: DCN3
Type: TYP1
INDATE3: Req data: IN-DATA3
OUTDATE3: resp data: OUT-DATA3

How is you awk program supposed to determine which input records produce output? (Why is there no output for the CID4 and CID5 input lines?)

How is you awk program supposed to know whether to print CID: or CID ID: on the second line of output for a given pair of CID input lines?

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.

Version 1.23.1							  Sun Jan 8 2012						      set_color(1)
