What are the two file viewing programs that were discussed in the lecture recordings? Specifically list the ones that let you interactively navigate the file.
Suppose we have a program named
MyProgram.javain the current directory. What is the command to run the compiled version of this program and have it read standard input from a file?
In your own words, describe the difference between running:and
grep "a" letters.txtWould you expect these two commands to have the same or different output? Why or why not?
cat letters.txt | grep "a"
Fill in the blanks below as to what “type” of object should go in each blank based on the type of operations we are performing. For each blank, use options:
filefor a file name
commandfor another command
command | _______ _______ | command command < _______ > _______ command < _______ | _______ command < _______ | _______ > _______
What command would tell us how many files (including hidden files) exist in our parent directory?
Suppose that I had a file named
MyOtherProgram.javain the current directory. What do you think would happen if I were to run
java MyOtherProgram.java > MyOtherProgram.java?
