[CentOS] Logrotate "firstaction" with non-0 exit status. Or: How to keep logrotate from rotating via scripts?
Hi, I'm wondering if anyone here has any experience with the "firstaction" script in logrotate config files, or more specifically, the behaviour with a non-0 exit status. The logrotate manpage says: firstaction/endscript The lines between firstaction and endscript (both of which must appear on lines by themselves) are executed (using /bin/sh) once before all log files that match the wildcarded pattern are rotated, before prerotate script is run and only if at least one log will actually be rotated. These directives may only appear inside a log file definition. Whole pattern is passed to the script as first argument. If the script exits with error, no further processing is done. See also lastaction. My question is, what exactly does "no further processing is done" mean? The obvious interpretation seems to be that the log file will not be rotated, but based on tests I've done, this does not seem to be the case. If I run logrotate with this config: /tmp/testfile { missingok size 0 rotate 1000 copytruncate firstaction false endscript } I get the message: error: error running first action script for /tmp/testfile But /tmp/testfile is still copied to /tmp/testfile.1 (provided that it exists.) Then if I run again, I end up with /tmp/testfile, /tmp/testfile.1 and /tmp/testfile.2, and so on... Does this mean the manpage note must be interpreted differently? Or is perhaps the behaviour buggy? And, is there any way at all I can use commands in the config file to control whether the rotation is done or not; this is what I'm looking for, really? I've tested this on CentOS release 5.8... - Toralf This e-mail, including any attachments and response string, may contain proprietary information which is confidential and may be legally privileged.
