Back up script
Trying to mess with a backup script but not having much luck
 If anyone can give a helping hand would be much appreciated. Im trying to get the script to: 1) Prompt for the name of the user account; 2) Prompt for the file name to be backed up 3) If the filename is a directory display the message "<Filename> is a directory" Else Backup the user file by copying it into users home directory Hope to get some help Cheers,

Show us what you have so far.
I assume it will have: A prompt for user name. A check to see if user is valid. A prompt for file to select A check on file type A check on permissions on source and target A copy A check of exit code from the copy

Sorry for late reply havent been on over weekend.
So far what i got i need a check on the setup,spacing and how exactly to finish the copy of the file. echo "Enter username:" read name if [ -d \home\$name ] then echo "Valid username" ls $name else echo "Invalid username" echo "enter filename" read file if [ -d $file] then echo "Valid file" else echo $file "is a directory" (not to sure whether $file should be inside the brackets here) now as for the actual backup will it just be a: cp source | $file not to sure here. Thanks in advance any help at all will be appreciated.

Ok, just a few pointers,as what you have is basically just about there.
Just checking that a directory called /home/$name exists does not prove that user exists/is valid. You do not have a check for null input when you prompt for data. Your if statements need a balancing fi to terminate them. The test for file/directory seems to be inverted from your original requirement. Some hints: Code:
# Obtain user name
echo "Enter username: \c"
read name
if [ "$name" = "" ]
then
echo "No name entered, exiting"
exit 2
fi
# Check user exists and get their home directory
namedir=`grep "^${name}:" /etc/passwd | awk -F: '{print {$?}'`
if [ "$namedir" = "" ]
then
echo "Invalid user"
exit 3
else
if [ ! -d $namedir]
then
echo "user home dir is not valid"
fi
fi
# Got here,so valid user, valid home dir.
# Now get file to backup
echo "Enter file to backup: \c"
read $file
if [ ["$file" = "" ]
then
echo "No file specified"
exit 4
fi
if [ -d $file ]
then
echo "$file is a directory"
elif [ ! -f $file ]
echo "$file is not a standard file or does not exist"
else
cp $file $namedir
cp_rc=$?
if [ [ $cp_rc -ne 0 ]
then
echo "backup of $file to $namedir failed - code $cp_rc"
fi
fi

Meant to say that the ? in the awk command is just a placeholder as I cannot, off the top of my head, remember which colon-delimited field the hoe directory is! Find that out and change the ? to the right number.
And it is nice to see someone willing to RTFM!
