join (pls help on join command)
Hi,

I am a new learner of join command. Some result really make me confused.
Please kindly help me.

input:
Code:
file1:
LEO oracle engineer 210375
P.Jones Office Runner ID897
L.Clip Personl Chief ID982
S.Round UNIX admin ID6

file2:
Dept2C ID897 6 years
Dept5Z ID982 1 year
Dept3S ID6 2 years
GEDA 210375 1 year
What i exactly want is:

ID897 P.Jones Office Runner Dept2C 6 years
ID982 L.Clip Personl Chief Dept5Z 1 year
ID6 S.Round UNIX admin Dept3S 2 years
210375 LEO oracle engineer GEDA 1 year
Follow is the code and result according to my example. Could anybody explain why the result is not correct. It seems my soaris can only output first two lines(since if i split the input file to four groups, and each group contain only one line, it works ok.)

ID897 P.Jones Office Runner Dept2C 6 years
