[SOLVED] [logrotate] why the stderr cannot be redirected to stdout?

utnubudnai · 11-26-2017, 08:34 PM

my command is this:

Code:

 logrotate  -v -f /opt/backup/logrotate.conf -s /opt/backup/logrotate.log 2>&1 >> /tmp/run.log

I intend to redirect all the outputs into the /tmp/run.log file, but I failed, I can see all the outputs within the console. below are the outputs.

Code:

reading config file /opt/backup/logrotate.conf

Handling 1 logs

rotating pattern: /opt/backup/config.tar  forced from command line (8 rotations)
empty log files are rotated, old logs are removed
considering log /opt/backup/config.tar
  log needs rotating
rotating log /opt/backup/config.tar, log->rotateCount is 8
dateext suffix '-20171127'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
destination /opt/backup/config.tar-20171127 already exists, skipping rotation

Try putting the 2>&1 *after* the >> /tmp/run.log
Idk why; let us know IF it works for you (it did for me)

Great, that works, but, how, why?

2>&1 directs stderr where stdin currently goes.
So you must first direct stdin to the file.

I'll google it, but the problem has been resolved now. I am closing it.
