Im a newbie to shell scripting - in fact you could even call me a Linux newbie, well, mabye not i started with CYGWIN a year ago... but i only just recently wiped the Windoze partition off my drive.
-Anyways, heres the script i have a problem with:

Code:

#!/bin/bash
#
#PeMPcoder

function invertconsole () {
echo -e "\033[7m"
}

function defconsole () {
echo -e "\033[0m"
}

function setinput () {
echo -e "file to encode:"
invertconsole
read file2encode
defconsole
}

function setoutput () {
echo -e "output PMP file(default is $file2encode.PMP)"
invertconsole
read pmpout
defconsole
}

function sudogui () {
while [ ! -n $inputfilefound ]
do
if test -n $file2encode -a "$file2encode" != ""
inputfilefound="yesitsdeclared"
else <--- Problem 'round here
setinput
fi
done
echo "succesful"
}
