Bug ID: 220924
Summary: bsdgrep(1) unexpectedly stops processing command line
arguments
Product: Base System
Version: 11.0-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
When searching for an empty expression '' with bsdgrep(1), processing of files
given on the command line stops when an empty file is encountered.
$ touch a
$ echo b > b
$ bsdgrep '' a b
$
The output is empty, while the expected output is a line containing 'b:b'.
This does not occur when passing the file names in the opposite order:
$ bsdgrep '' b a
b:b
$
Note that grep(1) (GNU grep) behaves as expected.
$ grep '' a b
b:b
$ grep '' b a
b:b
$
