Re: loop through records

[Tony Zanella]

awk may be a help here. Using it, you can refer to fields, like so:

$ cat f1
187431346 0323 mirrored 11866
187431346 0324 mirrored 11866
187431346 0325 mirrored 11866
187431346 0326 mirrored 11866

$ awk '{print $1;print$2}' f1
187431346
0323
187431346
0324
187431346
0325
187431346
0326
