Old logs are not deleted

[proninyaroslav]

I use rsync-incremental-backup-system and rsync-incremental-backup-system-remote scripts.
I have the maxLogFiles option set to 7, but when deleting the logs I see the following error on the sender side:

[2022-06-15T20:45:40+0300] Deleting excess of logs at target
tail: unable to open '+7' for reading: No such file or directory

My options:

backupDepth = 7
maxLogFiles = 7
useChecksum = 
useCompression = 1
additionalFlags = 
interactiveMode = no

Hi, I'm not able to reproduce this on my environment, but I think it may be caused by using an old version of bash at remote (assuming your output example came from rsync-incremental-backup-system-remote).

Can you run bash --version at your remote server and share output? Here is mine, as reference:

$ bash --version

Or maybe the outdated is tail itself. Here is my version output:

$ tail --version

OS: Fedora 36 (although I observed this problem on 35)
bash: 5.1.16(1)-release (x86_64-redhat-linux-gnu)
tail: 9.0

Hmm.. no old versions there.

Can you confirm with tail --help that you have -n, --lines=[+]NUM option available? If it is there, I can include -n to prefix the offset parameter (instead of using this wshorthand).

[proninyaroslav]

Yes

  -n, --lines=[+]NUM       output the last NUM lines, instead of the last 10;
                             or use -n +NUM to output starting with line NUM

Thanks!

[proninyaroslav]

Thank you, I will test it

[proninyaroslav]

Yes, works fine
