Whoo hoo! Finally after working on this all day I finished it. I feel so accomplished now.
Code:
#!/bin/bash
# Program: myrm
if [ "$#" -le 0 ]
then
echo "Not enough arguments"
echo "Usage: myrm [arg1] [myarg2] etc.."
fi
if [ -z "$MAXFILES" ]
then
for i in $1 $2 $3 $4 $5 $6 $7 $8 $9 ${10}
do
rm -rf $i
shift
done
exit 1
fi
x=$(ls | wc -l)
if [ -n "$MAXFILES" -a "$#" -lt "$MAXFILES" ]
then
rm -rf $*
else
echo "Remove $# files? (y/n)"
read choice
case "$choice"
in
y) rm -rf $*;;
n) echo "Ok, I will not delete any files then";;
*) echo "Invalid option"
exit;;
esac
fi
And here is how it works:
Code:
$ ls
f1 f10 f11 f12 f13 f14 f15 f2 f3 f4 f5 f6 f7 f8 f9 myrm
$ MAXFILES= ./myrm f*
$ ls
f5 f6 f7 f8 f9 myrm
# MAXFILES is set to null and deletes up to 10 files even though I specified more.
$ MAXFILES=2 ./myrm f1 f2 f3 f4 f5
Remove 5 files? (y/n)
y
$ ls
f10 f11 f12 f13 f14 f15 f6 f7 f8 f9 myrm
# MAXFILES is set to 2 but I specified 5 files to delete. So it asks me y/n to confirm.
$ MAXFILES=5 ./myrm f1 f2 f3
$ ls
f10 f11 f12 f13 f14 f15 f4 f5 f6 f7 f8 f9 myrm
$
# MAXFILES is set to 5 and since I have specifed less than 5 arguments, it just does it without question.
Now that I have getch() to work, I have yet another problem. BTW, thank you for answering these questions, I do ask a lot, only because I am eager to know, what is a board used for anyways :)
Ok, he's the problem...

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.
