|
||||
|
||||
B<2search> searches a sorted file for a string. It outputs the
|
||||
following line or the byte position of this line, which is where the
|
||||
string would have been if it had been in the sorted file.
|
||||
B<2search> searches a sorted file for lines starting with a string. It
|
||||
outputs the following line or the byte position of this line, which is
|
||||
where the string would have been if it had been in the sorted file.
|
||||
|
||||
B<2grep> output all lines starting with a given string. The file must
|
||||
be sorted.
|
||||
|
||||
By using B<-k> the same way as in B<sort> you can instead search for
|
||||
strings in columns, if the file is sorted using the B<-k> syntax.
