if in my file consist with record like this :
AAA1234567
BBB3314134
AAA1232134
CCC1231232
DDD0980980
AAA8098090
And I want to delete record
which substring(record,1,3)="AAA".
Is it possible to do that (deleting specific record) by unix shell script or perl without coding any high level language (like C or java).
if it is possible, what is the command/ statement ?
thank's for your kind answer.
