[Trisquel-users] Re : Script needed to compare one two-column file with another two-column file

As far as I understand, amenex wants a "natural join".  Also, you could write  
'sort -u SmallerFile.txt LargerFile.txt' instead of 'cat SmallerFile.txt  
LargerFile.txt | sort | uniq', which is not only uselessly long but also much  
slower in presence of many duplicates.
