"-s" switch is not working bash shell script. It throws error without prompting for the password.
Using: Ubuntu 16.04.6 LTS
Am i missing anything?
#!/bin/bash
echo "Enter password"
read -s password
echo "password:" $password
Enter password test.sh: 4: read: Illegal option -s password:
You are running the script with sh, not bash which provides the functionality in question. Either invoke the script directly with bash:
bash test.sh
Or make the file executable so the interpreter will read your shebang:
chmod +x test.sh # only required once
./test.sh
The .sh extension is unnecessary unless you are running actual POSIX shell scripts in certain special directories.
