[GLLUG] Merging Records in Input

[Mick Farmer]

Dear GLLUGers,

I have an input consisting of two fields such as

...
7 010c
7 060b
8 003d
8 003g
8 005n
8 008c
8 010a
9 100c
11 005m
11 013a
...

which I want to merge on the first field (key) as follows

...
7 010c 060b
8 003d 003g 005n 008c 010a
9 100c
11 005m 013m
...

I'm sure there's a UNIX utility that does this (sort?, uniq?) but can't
currently find it.  Can anyone help?

Many thanks in advance.

Regards,

Mick
