3. Write a shell script called access_file.sh which accepts one parameter and changes the permissions to 755
4. Write a shell script called unaccessible_sh.sh which accepts one parameter and changes the permissions to 300
5. Using sed write the command to replace all instances of the name "foo" with the string "bar" in a file called baz.txt
6. Write the command to only print out all of the pids using awk
7. Type in the df -h command - it will show you much space you have on your hard drive. Using the awk command, print out only the first percentage capacity.
