→INVESTIGATION 2: FILE PERMISSIONS
# Perform a '''mathematical calculation''' by taking the octal number '''777''' and <u>subtracting</u><br>the default umask value you determined in the previous step. What is the result?<br><br>
# Convert that octal number result to a '''binary''' number. What does that represent as newly created directory permissions?<br>Does that correspond to the permissions for the newly created '''~/shared''' directory?<br><br>
# Repeat '''steps the calculation (like in step #2528) but with a umask setting of ''' and '''#26077''' to see how a this new umask setting of '''077''' would affect permissions of newly-created directories.<br><br>
# Issue the following Linux command: <span style="color:blue;font-weight:bold;font-family:courier;">umask 077</span><br><br>
# Issue the following Linux command (without arguments): <span style="color:blue;font-weight:bold;font-family:courier;">umask</span><br><br>NOTE: You should notice the value '''0077'''. By dropping the leading zero to the left,<br> that would provide the default '''umask value of 077'''.<br><br>
