NET 4000 Chapter Notes - Chapter 1.7.5: Bucket Sort, Nonesuch Records, Standard Streams
Document Summary
Administrators often use the following methods to manipulate information created by shell commands: Redirection directs standard input, output, and error streams to locations other than the default. By default, the linux system classifies information with the following file descriptors: Linux commands use the greater than symbol (>) to show redirection of output, the less than symbol arrow (>) to append output to an existing file. If you use a single greater than symbol (>) to redirect output to a file and that file already exists, its contents will be overwritten. To preserve the contents of the file, use the double greater than symbol (>>). The tee command writes to standard output and redirects it to a file at the same time. Piping directs the output of one command into the input of another command. Can combine several commands to make a text stream.
