Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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.

Description of problem:
Lets say you have script like this on a RHEL 8 system that is also running sssd  daemon and you would like to get it's PID using pidof and your bash script happens to be named "sssd"

cat sssd 
#!/bin/bash
echo "my pid is $$"
echo "normal pidof:"
pidof sssd
echo "pidof with -x"
echo "-x     Scripts too - this causes the program to also return process id's of shells running the named scripts."
pidof -x sssd
echo 

Trying to run this on RHEL 8.2 works as expected:
./sssd 
my pid is 3286240
normal pidof:
945
pidof with -x
-x     Scripts too - this causes the program to also return process id's of shells running the named scripts.
3286240 945

Trying to run this on RHEL 8.3 works in a unexpected way:
./sssd 
my pid is 26311
normal pidof:
26311 1096
pidof with -x
-x     Scripts too - this causes the program to also return process id's of shells running the named scripts.
26311 1096

it returns the running scripts PID even though "-x" was not given as a parameter to pidof
