Topic
An updated grep package that fixes various bugs is now available.
Description
Grep searches through textual input for lines matching a regular
expression.
This updated grep package includes fixes for the following bugs:
- while searching certain immense binary files in which the newline
character did not appear for large expanses (for hundreds of megabytes of
text, for instance), grep may have missed a subsequent match. Because the
grep utility is not intended to process arbitrarily-long files in this
manner, this updated version now exits with a "line too long" error message
and an appropriate error code under these conditions. (BZ#483073)
- when operating on particular multi-byte character sets (but not, notably,
UTF-8), grep could enter an infinite loop and become unresponsive. This has
been fixed in this updated package so that grep is once again able to
process these multi-byte character sets without hanging. (BZ#479151)
- certain output control option combinations could cause the grep tool to
segmentation fault. With this updated package, these combinations work as
expected and no longer cause a segmentation fault. (BZ#452127)
- the example attached to the "--label" option description was not
illustrative enough: as documented, the option actually had no effect. The
updated package contains an improved example that shows the "--label"
option's utility, both in the manual and info pages. (BZ#484366)
All users of grep are advised to upgrade to this updated package, which
resolves these issues.
