Command line history, I/O redirection, and piping
* history [options] – to display the command line history.
* key – to complete a partially typed file/directory name or command.
* <↑> / <↓> keys – to navigate the command history buffer.
* ; – to separate multiple commands on a single line. Ffor example command1 ; command2.
* >,>> – to redirect the output of a command. For example ls -la directoryname > myfile.txt will write the output of the ls command to the file myfile.txt (and not to the screen!) while overwriting any previous contents of the file. If >> is used instead of > the original contents of the file myfile.txt will not be ereased but the output of ls will be appended to it.
* < – to use a specific file as an input to a command. For example cpio [options] < filenamelistfile.txt
* | – to pipe the output of one command to another command. Ffor example ls -al directoryname | less.
