Handle $ character in a string

MaryG · 09-11-2009, 02:27 AM

Hi.

I'm new with linux.

I have bash script.
In this script I ask in imput a password and it is like this: wdifg$aa

As you can see there is the $ character in it.

So when I use it I got an error.
I have to replace that password with this: "wdifg\$aa"

How can I do this?

Just incase the string in single quotes:

Code:

# echo '$date'
$date

read -ep pwd_user

aa=$pwd_user

echo $aa

If I execute this echo command doesn't show anything.

Quote the variables if you want to display their contents textually.

Code:

echo "$aa"

Why did you use the -e option?

Try

Code:

read -p 'Enter password: ' pwd_user
echo "DEBUG: pwd_user: '$pwd_user'"

or

Code:

read -p 'Enter password: '
pwd_user="$REPLY'
echo "DEBUG: pwd_user: '$pwd_user'"
