Culprit commit: caed210

The bug report doesn' follow the bug report template, e.g. doesn't state the version, expected behavior or use case. But I'll assume that the request here is to help in environments with and without less command. E.g. if there is less then show the output "paged" if not then print everything.

Also, the possible view on the bug could be that the respected client package doesn't depend on less.

a workaround is to set PAGER environment variable to a utility that can be used instead of less.

PAGER=more
export PAGER
ipa help commands

Easy fix: add less to package dependencies for python2-ipalib and python3-ipalib.

+1. If FreeIPA's code calls external less, it should make sure it is installed via rpm Requires.

Note that there is already support for $PAGER. What is missing is the test for the executable existence.

If the pager lookup is extracted from open_in_pager() then this would be pretty trivial:

pager = get_pager()
if os.path.exists(pager): open_in_pager(pager, data)
else: for something in something: print

Fixed. Added checking of a pager's executable before subprocess.Popen.

If PAGER environment variable is defined check it - do which (check the path, is it a file and check does it has +x). If it is ok - use a pager, otherwise - print function.
