RHBA-2014:0755 - Bug Fix Advisory

Topic

Updated less packages that fix one bug are now available for Red Hat Enterprise
Linux 6.

Description

The "less" utility is a text file browser that resembles "more", but allows
users to move backwards in the file as well as forwards. Since "less" does not
read the entire input file at startup, it also starts more quickly than ordinary
text editors.

This update fixes the following bug:

• Previously, the lesspipe script returned incorrect exit status codes. As a

consequence, the less utility failed to decompress empty files that had been
compressed with the gzip utility, and an unwanted message was displayed. With
this update, a pipe character ("|") has been added in front of the LESSOPEN
environment variable to enforce a new default behavior of lesspipe. For backward
compatibility, lesspipe has the same behavior if LESSOPEN remains unchanged. As
a result, the less utility now detects and displays empty files correctly.
(BZ#615303)

Users of less are advised to upgrade to these updated packages, which fix this
bug.
