Hello,
Something drive me crazy lol
I make a script to move new file to my nas, here the script:
#!/bin/bash
TYPE='move'
SDIR='/home/my_user/torrents/rtorrent/0. Complete'
rGD='DS920_WebDAV:'
TDIR='/download/0. Torrents/'
CONF='/root/.config/rclone/rclone.conf'
LOG='/var/log/rclone_move_ds920.log'
rclone "$TYPE" "$SDIR" "$rGD$TDIR" \
--config="$CONF" \
-c \
--exclude ".unionfs-fuse/**" \
--min-age 5m \
--log-file="$LOG"
And it works, except for the log file.
I always have the message : "--log-file=/var/log/rclone_move_ds920.log: No such file or directory"
But the folder /var/log exists...
Even if I manually create a rclone_move_ds920.log, i've got the same error.
Do you see why ?
Thank you 
Permission issue? Need to see the actual command / full output...
yes, so :
script file : /usr/share/scripts/rclone_move_ds920.sh
make executable with chmod a+x
for testing, launch via : /usr/share/scripts/rclone_move_ds920.sh
and the result :
/usr/share/rclone_move_ds920.sh: line 15: --log-file=/var/log/rclone_move_ds920.log: No such file or directory
thanks for your help 
No, permissions on creating the log file for that user. Not the script.
Run the command as the user without any script and validate it works.
Sorry. I run the command without script an it works perfectly, the log is created.
I give the good permission and know it works...
I thought I had done so
Sorry for the inconvenience anf thank you for your help
