Need help before i crack up!
Hi guys, i'm new to the forum, i need a script badly everything i try is awful as i'm new to this and usually i jump in at the deepend....however this unix scripting has got the better of me...hope someone can help!

firstly the script will prompt the user for a filename in the current directory, if the file exists it will then prompt for a directory in which to copy the file, if the directory does not exist one will be created and then the file will be copied...and also inform the user if the file was not found.

If anyone can help with this i would greatly appreciate it....i don't have any code as everything i've tried fails and i delete it.

Why don't you have any code? Surely there are some parts of the problem that you can solve.

The first thing to do is to break down the problem into its individual parts, then write the code for each one;

Code:
## print the prompt

## read the user's input

## check that the file exists

## prompt for directory

## check for directory's existsence

## if necessary, create directory

## copy the file

I got as far as this but when i tried to prompt for a directory it shuts back down to the menu, as i say i'm very new to this...almost ashamed to post such pathetic code.

echo "Enter file name: ";
read fname;

if [ -f $fname ];
then

Ok... so start with what you have and build on it
Code:
#!/bin/sh

## print the prompt
echo "Enter file name:";

## read the user's input
read FNAME;

## check that the file exists
if [ -f $FNAME ]; then
   echo "$FNAME found"

   ## prompt for directory
   DO SOMETHING

   ## check for directory's existsence
   DO SOMETHING

   ## if necessary, create directory
   DO SOMETHING

   ## copy the file
   DO SOMETHING

   exit
fi

## do something if the file does not exist
echo "$FNAME not found"
exit

Please put code inside [code] tags.

Code:
You don't need the semi-colons.

Quote:
Code:
    read fname;
 
if [ -f $fname ];
then


Once you finish the if statement, you are half way there.

Code:
if [ -f $fname ]
then
  : do whatever
fi

The next section is simply a repetition of what you already have with slight variations.

New problem:

when the file is not found i want it to return to the menu, however it carries out the next line when i hit a key

Iknow its probably something simple can anyone help?

here is my pause function: function pause(){
read -s -n 1 -p "Press any key to return to Menu . . ."
echo
}

SCRIPT CODE

echo "Enter file name: "
read fname;

if [ -f $fname ]; then
echo "$fname found"
else
echo "$fname not found"
pause
fi
echo "Enter directory for file to be copied to: "
read dname;
if [ -d $dname ]; then
cp $fname $dname
echo "file copied"
sleep 5
else
echo "$dname not found"
sleep 5

fi;;
