hello...
i have one question can you help me...???
please..

Write a script (Named execadd.sh) that will take a single filename as an argument and adds execute permission to the file for the user, but only if the file is a regular file.
Your script must check to see that there is exactly one argument. If there are no arguments or more than one arguments, your script must produce a "usage" message that tells how to use the script. You write it this way:
echo "Usage: $0 filename"
You must check to see if the file exists; if it doesn't, give an error message. You must check to see if the file is a regular file; if not, give an appropriate message

Try

Code:

#!/bin/bash
FILE=$1

usage(){
    echo "Usage: $0 filename"
    exit 1
}

[ $# -ne 1 ] && usage

if [ -f $FILE ]
then
    chmod +x $FILE
else
    echo "Error: $FILE not a regular file."
fi

usage(){
echo "Usage: $0 filename"
exit 1
}

[ $# -ne 1 ] && usage

if [ -f $FILE ]
then
chmod +x $FILE
else
echo "Error: $FILE not a regular file."
fi
