I've been trying to update my backup script such that it saves data on a remote server instead of on a local disk.
I have succeeded in converting the entire script but the last part in which I remove all the files from the directory except the
In order to debug and pinpoint the cause I have temporarily removed all variables.
The command I wish to run on my remote machine is the following:
ls -tr1 /mnt/backup1tb/testarossa/test | tail -n +5 | xargs -d '\n' rm -f
When I execute this command it does what I expect it to do. It leaves the newest 4 files (or directories) and removes the rest.
To execute it over SSH I have the following line in my script:
foo=`ssh $remoteuser@$remoteaddr ls -tr1 /mnt/backup1tb/testarossa/test | tail -n +5 | xargs -d '\n' rm -f`
I have tried removing the last part, the
| xargs -d '\n' rm -f and that indeed returns the directory listing of files that need removal. Howeve, adding the xarg part does not remove the files.
