DAg,

ik zou wel één GROTE tabel willen, waar ALLE gegevns in staan (of bijna 
alle), omdat zo de verwerking en generatie van alle spullen makkelijker 
en overzichtelijker is.  Dat geeft wel redundantie, maar .. we betalen 
ervoor...

Nu ken ik een commando "join"
        -a FILENUM
               print  unpairable lines coming from file FILENUM, where 
FILENUM is 1 or 2,
               corresponding to FILE1 or FILE2

        -e EMPTY
               replace missing input fields with EMPTY

        -i, --ignore-case
               ignore differences in case when comparing fields

        -j FIELD
               equivalent to `-1 FIELD -2 FIELD'

        -o FORMAT
               obey FORMAT while constructing output line

        -t CHAR
               use CHAR as input and output field separator

        -v FILENUM
               like -a FILENUM, but suppress joined output lines

        -1 FIELD
               join on this FIELD of file 1

        -2 FIELD
               join on this FIELD of file 2

        --check-order
               check that the input is correctly sorted, even  if  all 
input  lines  are
               pairable


Iemand ermee vertrouwd??

Marc
