RudiC, not to over complicate things, assume there is a loop through all the data files and the variables FilePathName, FilePath, FileName, Var1, ..., Var6 are defined within the loop before the code is called.

The transpose with padding code will be called for one file at a time within the loop. If awk is used, the variables can be passed using the -v option as needed. Var1-6 are not needed in the awk so they can be passed as one concatenated string.

After the loop, the sort is done and duplicate columns will be deleted. If you don't want to keep it general, assume it is the last two colums FilePath and FileName that are not part of the duplicate line determination.

NAME
pr - print file SYNOPSIS
pr [ option ... ] [ file ... ] DESCRIPTION
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name of the file or a specified header, and the page number. With no file arguments, pr prints its standard input. Options apply to all following files but may be reset between files: -n Produce n-column output. +n Begin printing with page n. -b Balance columns on last page, in case of multi-column output. -d Double space. -en Set the tab stops for input text every n spaces. -h Take the next argument as a page header (file by default). -in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces. -f Use formfeeds to separate pages. -ln Take the length of the page to be n lines instead of the default 66. -m Print all files simultaneously, each in one column. -n Number the lines of each file. -on Offset the left margin n character positions. -sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab. -t Do not print the 5-line header or the 5-line trailer normally supplied for each page. -wn For multi-column output, take the width of the page to be n characters instead of the default 72.
