I have a file, we'll call it file.txt. It has thousands of lines of all kinds of output at any given time (ie. foo bar foo bar)
I need to copy out just a portion of the file from Point-A to Point-B. I'd like to save off just that portion to a file called test123xyz.txt.
How do I do that?

Hello,
We have edi files we need to do some extra parsing on.
There is a line that shows up that looks like this:
GE|8,845|000000000
We need to parse the file, find the line ( that begins with GE "^GE" ), and remove the comma(s).
What is the easiest way to do that ? I know I can grab... (5 Replies)

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.
