Redirect – ls command creates file called file_list.txt instead of sending to stdout:
$ ls > file_list.txt
Redirect Append – ls command appends file_list.txt instead of sending to stdout:
$ ls >> file_list.txt
Pipe – sends output of ls command to less command:
$ ls | less
Pipes can be stacked:
$ ps aux | grep conky | grep -v grep | awk '{print $2}' | xargs kill
If you pipe to the command ‘tee’, the command output goes to stdout and a file of your choice:
$ ls | tee file_list.txt
