→INVESTIGATION 2: FILE PERMISSIONS
# Perform a mathematical calculation by taking the octal number '''777''' and subtracting the default umask value you determined in the previous step.<br>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 #27''' and '''#28''' to see how a 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>
# 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, that would provide the default '''umask value of 077'''.<br><br>
# Issue the following Linux command: <span style="color:blue;font-weight:bold;font-family:courier;">mkdir ~/shared2</span><br><br>
# Issue the following Linux command: <span style="color:blue;font-weight:bold;font-family:courier;">ls -ld ~/shared2</span><br><br>Do the permissions for this newly created directory match the predicted permissions that you calculated in step #?<br><br>\
