Masking Password from within a Bash Shell Script
Is there a way to mask the password inside of a script to minimize the impact of a comprimised server? So

Code:
ssh -o "PasswordAuthentication no" -o "HostbasedAuthentication yes" -l testuser 192.168.3.1 "mysqldump --opt --all-databases -u root -pPassword| gzip" > $backup_dir/mysqldump.gz

a seperate password file maybe and using backticks? Just throwing stuff out there

Code:
ssh -o "PasswordAuthentication no" -o "HostbasedAuthentication yes" -l testuser 192.168.3.1 "mysqldump --opt --all-databases -u root -p`cat /some/dir/passwd_file`| gzip" > $backup_dir/mysqldump.gz

That won't mask it, no. It'll still show it because it'll have to figure out what the password is before it runs the command, how else could it do it?

If you could give mysql just -p instead of '-ppassword' it might read it from stdin, so you could redirect a local file into ssh.
