bsearch utility

[Sorav Bansal]

Hi,

I often use the 'sort' program often for sorting text files. Recently, I 
had to write a binary search utility that can search for a key in a file 
sorted using the 'sort' program. The command line 'bsearch' utility 
takes similar arguments to the sort program.

Since bsearch is a common operation on sorted files, I imagine it will 
be a useful utility to add to coreutils. If there is enough interest, I 
would be happy to write and maintain bsearch for coreutils. The basic 
program functionality is already working and tested, and it needs 
support for more command-line options and documentation before it is 
ready for coreutils.

Please let me know, if you think it would be useful to make bsearch a 
part of coreutils.

Regards,

Sorav
