Code:
perl -lne # Invoke perl with options -l -n and -e.
-l for adding \n each time it prints something. 
-n to read the input file line by line. 
-e to tell the shell that the following instructions are commands to be sent to the perl interpreter.
'BEGIN{open O,">output.txt"}; # BEGIN block runs only once at the start of the program. Opens the file output.txt in handle O for writing.
if(/^xtopShared/../;$/) { # Find lines between (and including) patterns /^stopShared/ and /;$/. In the world of perl, this is known as flipflop operator
    while (/(\w+?_sh)/g) {print O "##### buildapi $1 nodebug.####"} # Pattern to match each of abcd_sh, ijk_sh, etc.. Continues to match iteratively.
}; END{close O} # END block runs only once during program execution just like BEGIN block and here we close the filehandle O.
' xtop_env.txt # Input file to be read

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)
