From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-1.3.1 Firefox/1.0.3 Description of problem: When running R (http://www.r-project.org/) version 2.1.0 in a console using 'sudo R', ctrl-c will exit R and return to the console command line, however leaving an R process running. This has been replicated with at least one prior R version as well. It appears that R is run in sesh in this situation. Presumably, ctrl-c kills sesh, but does not kill R. A bug was filed in the R bug tracking system: http://r-bugs.biostat.ku.dk/cgi-bin/R/incoming?id=7819;user=guest;selectid=7819 However this appears to be related to using "sudo R" when SELinux is enabled, as the ctrl-c behavior does not occur when SELinux is disabled. Relevant output from "ps -aux" shows: root 12272 49.2 0.8 23108 16924 ? R 07:45 2:07 /usr/local/lib/R/bin/exec/R root 15503 0.0 0.0 2556 252 pts/1 S+ 07:46 0:00 sesh /usr/local/bin/R root 15626 0.5 0.8 23204 16920 pts/1 S+ 07:46 0:00 /usr/local/lib/R/bin/exec/R The first R session is what remains from the prior ctrl-c event. Relevant content from /etc/sudoers is: marcs ALL=(ALL) ALL Version-Release number of selected component (if applicable): sudo-1.6.7p5-30.1 How reproducible: Always Steps to Reproduce: With SELinux enabled: 1. Run "sudo R" from a terminal emulator 2. Enter password 3. R loads 4. Press ctrl-c once at the R prompt Actual Results: It appears that sesh is killed, exiting the R session. However an R process remains. Expected Results: Presumably ctrl-c should not kill sesh and the R session Additional info:
*** Bug 156086 has been marked as a duplicate of this bug. ***
The sudo command doesn't use sesh in distributions >=FC5. Closing.
