Help with awk replacing identical columns based on another file
Hello,
I am using Awk in UBUNTU 12.04.
I have a file like following with three fields and 44706 rows.
F1 A A
F2 G G
F3 A T
I have another file like this:
AL_1 F1 A A
AL_2 F1 A T
AL_3 F1 A A
AL_1 F2 G G
AL_2 F2 G A
AL_3 F2 G G
BO_1 F1 A A
BO_2 F1 A T
BO_1 F2 G A
BO_2 F2 G G
CO_1 F1 A T
CO_2 F1 T T
CO_1 F2 G G
CO_2 F2 G A
( I didn't write for F3 anymore but it contains F3 as well)
This sounds a bit complex. What I want to have is like this:
F1 A T
F2 G A
F3 A T
Sorry as this sounds complex. So, what I want to do is to look in the second file for a "F1" whose 3rd and 4th fields are not the same (i.e. A T instead of A A) and replace it in the first file for "F1".
So, for F2, F3 and the rest.
Thank you very much for any help.

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.
