Bash script to open, read, and write then save....
- by Alex Vo
I'm new on this bash script thing. Can you show me some example on writing Bash script. I want to write a script that can read from a filename and save it to a variable; increment the value of the variable and write that variable back to the file and save it. This is what I have started and stuck on it so far.
#!/bin/bash
# if file exist
#echo "Testing \ "$1""
if [ -f "$1" ]; then
echo "$1 does exist"
else
echo "$1 does not exist!"
echo "Creating $1"
touch $1
echo "This is test" > $1
exit 1
fi
#echo "Testing \ "$2""
if [ "$2" == "" ]; then
echo "Enter the filename"
elif [ -f "$2" ]; then
echo "$2 Fille does exist"
else
echo "$2 File doesn't exist"
echo "Creating $2"
touch $2
exit 1
fi
counter=1
echo -n "Enter a file name : "
read file
if [ ! -f $file ]
then
echo "$file not a file!"
exit 1
fi
