[amp_mcq option1=”chmod go + x, u – x letter” option2=”chmod g – x, uo + r letter” option3=”chmod go + r, u + x letter” option4=”chmod u – x, go + r letter E. None of the above” correct=”option4″]<\/p>\n
The correct answer is D. chmod u – x, go + r letter.<\/p>\n
The chmod command is used to change the permissions of a file. The first argument is the mode, which is a combination of three octal digits. The first digit specifies the permissions for the owner of the file, the second digit specifies the permissions for the group that owns the file, and the third digit specifies the permissions for everyone else.<\/p>\n
The letters r, w, and x represent read, write, and execute permissions, respectively. A dash (-) indicates that a permission is not granted.<\/p>\n
In this case, we want to remove the executable permission from the user (u) and assign read permission to the group (g) and others (o). This can be done by using the following command:<\/p>\n
This command will change the permissions of the file named “letter” to the following:<\/p>\n This means that the owner of the file will only be able to read the file, the group will be able to read and write the file, and everyone else will only be able to read the file.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”chmod go + x, u – x letter” option2=”chmod g – x, uo + r letter” option3=”chmod go + r, u + x letter” option4=”chmod u – x, go + r letter E.
