The replacement part itself ( replaceScript.sh script ) is not very hard. The point is that the *ABC scripts will be running multiple times, and after their first change through the replacement script, there won't be any more tags @..@ left in them ( or am I missing something here ? ), and you need to change those values back again in the future.

Code:
    before 			after
VAR_MAN_NAME="@MAN_NAME@"  VAR_MAN_NAME=other         NO more tags @..@!
VAR_PORT_NUM="@PORT_NUM@"  VAR_PORT_NUM=1001 
VAR_TEST_NUM="@TEST_NUM@"  VAR_TEST_NUM=20

So how are you planning to rechange the new values ( other,1001,20,...) to the old tag values @..@, for the next run ?

Are the variable names VAR_MAN_NAME, VAR_PORT_NUM,..., the same in all *ABC scripts ? If so, you can replace their values based on their unique names in all the files.

Another way, you might use their same record number ( NR ) in all the files, if they are in the same position.

I think you need to provide more details about the unique properties of these variables.

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.
