Top Forums UNIX for Advanced & Expert Users Want to get average value for each hour Post 302940357 by mjf on Friday 3rd of April 2015 09:25:48 PM

I understand the concatenation but what I'm not getting is why the extra digits being added are off by one for each line. For example, for line 3, I would expect the extra digit in red to be 1 instead of 0 as count is 1. So why it is that count[$1 hour]++ is 0 when it's concatenated to the array for line 3?

Code:
 
line    array["03/02/2015 00"]        count["03/02/2015 00"]  
  3     24.560                                 1    
  4     24.560 + 24.401 (48.961)               2 
  5     48.961 + 23.232 (72.193)               3

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)
