I think you're misunderstanding what I'm trying to do.
First lets start with this:
I don't see how it's too little too late. It's doing exactly what the shell should do. Single quotes don't expand anything and double quotes allow expansion. If you set a variable to '*' then it literally equals *, however if instead you set it to just * then glob comes into play and you get an array containing all of the files/directories in your current directory.
I'm currectly writing a program to do this I did post all the code I had in the first post. Which works almost as it should. If you give it a file that is newline seperated such as:
It currently loops through and prints the following (I'm only going to show the last line):
So for the argument opt4' I expect to see 'opt4'\'''. In this case I'm getting 'opt4'\' which means the part that replacess all occurences of ' with '\'' isn't working correctly. It also isn't consistent as for arg 2 ' is replaced with just '\
I think the code makes it clear that I'm simply replacing all occurences of ' with '\'' and then appending ' to the begining and end of each string/arg. This because everything in between the two single quotes will not be expanded and will be read literally. However the shell isn't capaple of allowing me to escape a ' in the middle of a single quoted string. (can't do: 'don't' can do 'don'\''t')
The final version would of course execute command and pass the args, however I want to see what is going to the command before I call it so I can verify if it's working which is why it currently just prints the args line per line.
When I open a file in vi, I see the following characters:
\302\240
Can someone explain what these characters mean. Is it ASCII format? I need to trim those characters from a file.
I am doing the following:
tr -d '\302\240'

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.
