Linux Command Merch

Setting 777 permissions to a file or directory means that it will be readable, writable and executable by all users and may pose a huge security risk. For example, if you recursively change the permissions of all files and subdirectories under the /var/www directory to 777, any user on the system will be able to create, delete or modify files in that directory. If you experience permission issues with your web server, instead of recursively setting the permission to 777, change the file’s ownership to the user running the application and set the file’s permissions to 644 and directory’s permissions to 755. File ownership can be changed using the chown command and permissions with the chmod command.

'whoami' command is used both in Unix Operating System and as well as in Windows Operating System. It is basically the concatenation of the strings “who”,”am”,”i” as whoami. It displays the username of the current user when this command is invoked. The whoami command prints the user name of the effective user ID. In other words, it displays the name of the currently logged-in user.

Linux CLI Sleep command is used to delay for a fixed amount of time during the execution of any script. When the coder needs to pause the execution of any command for the particular purpose then this command is used with the particular time value. You can set the delay amount by seconds, minutes, hours and days.

Funny command (and so dangerous) for Linux users. Hope it bring to you a lot of laughs to make an awesome with Linux.
