Top Forums Shell Programming and Scripting How to put the command to remove duplicate lines in my awk script? Post 303037748 by Don Cragun on Monday 12th of August 2019 05:06:10 PM

Please show us the exact output you hope to produce from the three sample files that we can assume were used to produce the output shown in the image you showed us in post #1 in this thread (preferably as text in CODE tags rather than as an image).

If you're trying to do what I think you are trying to do, you cannot use !a[$0]++ to filter your input because it will throw away input before you know whether or not you will want to print it. I think you need to read all of your input files and then compare the data for each LPARS value. If and only if all of the entries are identical, then you can decide not to print that row of output.

Note that in your sample input file shown in post #1 in this thread, you showed us two lines that seem to be in completely different formats. Please explain what the real format is for your input files.

It is also unclear as to whether or not all of the input files will contain an entry for each LPARS value. If a record for a specific LPARS value is not included in a file, should that be treated as a "different" value causing a line to be printed? Or should a file be ignored when determining whether or not to print an LPARS value line if there is no entry for that LPARS value in that file?
