Hi anbu23,

Thanks for this. I'm not on Solaris so I've made a minor change (at least that's why I think I had to change it...)

Code:

 /test/nigelp> awk -F, -f alg_awk_2 test.alg | sort -t, +3n      
TEST:HOME,01010515,20061230204800,,0794,10,DIAG;                    
TEST:HOME,0102050A,20061230205838,,1094,10,DIAG;                    
TEST:HOME,01020518,20061230213158,,2844,10,DIAG;                    
TEST:HOME,01020502,20061230185622,,7397,10,DIAG;                    
TEST:HOME,01010513,20061230195958,,8721,10,DIAG;                    
TEST:HOME,0102051A,20061230201042,,8998,10,DIAG;                    
TEST:HOME,01020514,20061230202733,,9620,10,DIAG;

Interestingly it's not sorting field 3 as I'd expect - it's a date time field which I would've thought should sort numerically. Am I doing something wrong?

Also I'd really like the sort to be contained within the awk to keep things elegant. Is there a way of doing this?

Many thanks, p.
