Development Journal

This is a journal the development process for this project. It is not intended to an extensive log of work, but rather a record of interesting challenges and errors and how they were resolved.

Redirection/Piping

Piping is a way to connect the output of one program to the input of another program without any temporary file.

Commands

  • ls -l lists the files in the current directory in long format.
  • wc -l counts the number of lines in the input.

Piping connects the output of ls -l to the input of wc -l.

ls -l | wc -l

To save the output of a command to a file (overwriting any existing content), use the > operator.

ls -l > file.txt

To append the output of a command to a file, use the >> operator.

ls -l >> file.txt
