Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Previously the command "less" wasn't working correctly. It produced a sequence of garbled characters when viewing the log or another file and it was hard to exit the current view page. This has been rectified using alias less "cat $1 | /usr/bin/less", so "less" works correctly now.

less
Description of problem:
"Less" is a program similar to "more", but actually the command "less" doesn't work well.
1. Tt will show as garbled sequence of characters when user view log or other file.
2. It is hard to exit the current view page.
Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.5-20130222.0.auto1707.el6.iso
ovirt-node-3.0.0-1.999.20130701111251git99aadc6.el6.noarch
How reproducible:
100%
Steps to Reproduce:
1. Install RHEV-H 6.5.
2. Login RHEV-H and drop to shell.
3. run command #less /var/log/ovirt.log
Actual results:
1. Command "less" doesn't work well, it will show as garbled sequence of characters when user view log or other file.
2. It is hard to exit the current view page.
Expected results:
Command "less" can work well.
Additional info:
Agree this is bad/ugly. We should definitely try to fix it, though it's not quite as high a priority since we don't support dropping to a shell and running commands manually.
It's unlikely that this will make 6.5. It may be a fundamental problem with urwid, but no method I've attempted (switching VTs, different urwid screen renderers has resolved). Design problem.

How is urwid impacting this? we're in a shell environment, aren't we?
can we implement a simple workaround like:
alias less "cat $1 | /usr/bin/less"

We can do this, which is surprising. I hadn't tried it (unnecessary use of cat and all that), but it works. urwid throws a ton of escape codes if you `less /some/file`, but works if you cat it first. I'll go that way.
