Sorry to be a pedant, but what command did you type?
All four of the sample commands posted contain logic errors, syntax errors, or typing errors? Space characters are very important in this type of command line.
These were the command lines posted: The first two are identical and have no space character after "-o". The third omits the "-o" switch. The fourth is not really relevant.
Quote:
join -t"|" -o'1.1 1.2 1.3 2.1 2.3' Courses.txt Grades.txt > Merged.txt
join -t"|" -o'1.1 1.2 1.3 2.1 2.3' Courses.txt Grades.txt > Merged.txt
join -t"|" -1 1 -2 1 Courses.txt Grades.txt > Merged.txt
join -t"|" -a1 Courses.txt Grades.txt > Merged.txt

Please post the exact command typed and run it on the sample data posted and then post the output (all within code tags).

On the off-chance .... have any of the data files been copied from a Microsoft Operating System?

Generates one hand with permutations and the tutorial for how to use them. --generate=N Generate N random boards --load=boards.txt Load boards+analysis from boards.txt --load-dds=boards.dds Load boards from boards.dds in dds format --load-analysis=tricks.txt Load analysis from tricks.txt --permutations=permutations.txt Generate the permutations and save them to the given file --curtains=curtains.txt Save curtain cards to file curtains.txt --save=boards.txt Save the boards+analysis to boards.txt --save-dds=boards.dds Save the boards to boards.dds in dds format --save-analysis=tricks.txt Save the analysis to tricks.txt --format=html|txt|pdf Set the output mode to the given format --title=title Set the title for the output --output=hands.txt Print the hands to hands.txt, rather than to standard output --stats Generate statistics about the set of boards; included in the hands output --analyze Run the dds analyzer on the boards and print the resulting numberof tricks (warning SLOW) --criteria= A list of criteria to apply to each generated hand to generate specific hand types. The list should be space separated and each item may be suffixed with a colon and a (fractional) probability value which can be used to weight the criteria. E.g. --criteria="weaknt:0.8 strongnt:0.5" Valid criteria are: unbalanced weaknt strongnt twont strongtwo weaktwo three twoclubs 4441 singlesuit twosuits partscore game slam game-invite slam-invite jumpshift jumpfit splinter bacon weird --probability=factor Generate hands matching the criteria with only the given probability. Factor is in the range 0 to 1. On each attempt to generate a board it is rejected if it doesn't match the criteria with the given probability. A factor of about 0.8 gives roughly half matching boards AUTHOR
