join

[Maarten . Vanneste]

Hello,

I have tried to use the "join" program to merge two large files (containing
thousands of separate lines both, and each file has at least 10 columns of
data). It appears that the join command, using the first column in each
file as the join field always stopped at about the same level. I have tried
a number of things to circumvent this issue, but to no avail. The final
solution was to split up my two input files and join the smaller files, and
afterwards using cat to put them back into one big file. This suggests that
the join command has a maximum number of lines it can read, is this correct
? From my test, it turns out to be somewhere around 6600 lines after which
the program terminates.

With kind regards,
Maarten
