Omit repeating lines
Can someone help me with the following 2 objectives? 1) The following command is just an example. It gets a list of all print jobs. From there I am trying to extract the printer name. It works with the following command: Code:
lpstat -W "completed" -o | awk -F- '{ print $1}'
Problem is, I want to be able to omit these multiple lines: Code:
My_office_printer My_office_printer My_office_printer My_home_printer My_home_printer So it looks like this: Code:
My_office_printer My_home_printer Now, each line is actually different (because each one is its own print job), but because I use awk to just get the name of the printer, the end result displays the printer name for however many print jobs there were. I just want one instance of each printer name. 2) In the previous section, I want to reduce the number of lines returned to one per printer. Before I do, I want to count how many there are. For example, how many time was My_office_printer listed. Any help is greatly appreciated.... |
