Concatenate text between patterns in individual strings
In any given file, wherever a certain data block exists I need to concatenate the values(text after each "=" sign) from that block. in that block. The block starts and ends with specific pattern, say BEGIN DS and END DS respectively. The block size may vary. A file will have multiple such blocks. So say if there are 6 such blocks then I need 6 strings which have data in those respective blocks. Kindly guide.

Eg. "$file" has content :
Code:
 
Some lines of 
text
Begin DS
var1=some
var2=text 2 b concatenated 
End DS 
some more 
data
Begin DS
var1=some more
var2=text
var3=2 concatenate in 
var4=next string
End DS
:
:
so on

OUTPUT :::
Code:
 
text 2 b concatenated 
some more text 2 concatenate in next string
:

I know how to use sed for this if the block size was fixed ...

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.
