In above sample when it reads the first line x != $2 is satisfied and 1 is assigned to x and this line is printed. In case of second line x != $2 is not satisfied and the line is not printed. In case of third line x != $2 is satisfied and 2 is assigned to x and this line is printed.
First it picks up the records begining with "access-list"
after that (Note: $2 represents the second field( that is 1 for the first line))
the statement x!=$2 would be true for the first time. and then 1 is being assigned
to x so x has the value 1. when the command processes the second line then $2=1 that
means x=$2 so this time the condition fails and so nothing is printed uptill it reaches
where $2 value is 2 it would continue to skip the lines. once it has reached where $2=2
then again the condition(x!=$2) is true and the record is printed and this time 2 is
assigned to x and this continues uptill the end of file. Incase, if the record doesnt
start with "access-list" then also print the line.

I have one base file, and multiple target files-- each have uniform line structure so no need to use grep to find things-- can just define sections by line number.

Hi everyone,

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.
