Creation Date: 97/10/21

Post Date:  97/10/24

Hardware Platforms - OS Releases:
	s700: 10.20
	s800: 10.20

Products: N/A

Filesets:
	OS-Core.UX-CORE

Automatic Reboot?: No

Path Name: /hp-ux_patches/s700_800/10.X/PHCO_12959

Symptoms:
	PHCO_12959:
	egrep -v 'bcd|^xxx' and egrep -v '^xxx|bcd' gives different
	outputs.

	PHCO_12722:
	grep '' file1 > file2 is inserting null characters.

	PHCO_10144:
	The grep command behaves incorrectly because of the
	misbehaviour of the regexec and regcomp libc routines.

	PHCO_9272:
	PHCO_8877 was built with an incorrect version
	of libc. Thus the performance improvements
	were not included in the patch.

	PHCO_8877:
	egrep is slower on 10.X than on 9.X.

Defect Description:
	PHCO_12959:
	egrep command behaves incorrectly for alternate regular
	expressions with anchored non-first subexpression if don't
	use parenthesis.

	PHCO_12722:
	grep '' file1 > file2 is inserting null characters
	in lines greater than 2046 characters.

	PHCO_10144:
	If the LANG is set to other than C, the command
	"grep -v '^$' <file> matches the non blank lines
	resulting in erroneous results.

	PHCO_9272:
	PHCO_8877 was build with an incorrect version
	of libc. Thus the performance improvements
	were not included in the patch.

	PHCO_8877:
	egrep is slower on 10.X than on 9.X.

Installation Instructions:

	SupportLine User Guide or your Hewlett-Packard support terms
	and conditions for precautions, scope of license,

	before installing this patch.
	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHCO_12959

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHCO_12959.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHCO_12959.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHCO_12959.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHCO_12959.text file to
	/var/adm/sw/patch for future reference.

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHCO_12959.depot of=/dev/rmt/0m bs=2k
