What are common pitfalls with passwd command?

Using the passwd command in Linux is essential for managing user passwords, but there are several common pitfalls that users may encounter. Here are a few to watch out for:

• Forgetting Current Password: When changing a password, users may forget the current password, which prevents them from changing their password using the command.
• Weak Passwords: Users often select weak passwords that do not comply with system security policies, leading to vulnerabilities.
• User Restrictions: Some users may not have the necessary permissions or may be restricted by administrators from changing passwords.
• Environment Variables: Dependencies on specific environment settings might lead to unexpected behaviors when using the command.
• Using the Wrong Syntax: A common error is using incorrect syntax or options when invoking the passwd command.
