1. Download
2. Extract
3. Make executable
4. Move to your custom folder
5. Use it

wget https://git.sitnikov.ga/gas/nextcloud_scripts/archive/master.zip
unzip master.zip
cd nextcloud_scripts
chmod +x *.sh
mv *.sh /usr/local/bin/
mv nextcloud-bot-links-list /usr/local/bin/nextcloud-bot-links-list
mv ./etc/nextcloud-scripts-config.conf /etc/nextcloud-scripts-config.conf

Run it under nextcloud user (for me it is www-data).

nextcloud-scripts-config.conf is a central configuration file, very handy if you are using more than one script from this bunch. Options are:

• Your NC OCC Command path e.g. Command=/var/www/nextcloud/occ
• Your NC log file path e.g. LogFile=/var/www/nextcloud/data/nextcloud.log
• Your log file path for other output if needed e.g. CronLogFile=/var/log/nextvloud-cron.log
• Your PHP location if different from default e.g. PHP=/usr/bin/php

Perform Audit log analyze for a given time and output in cacti format. "Auditing / Logging" App must be enabled. Example:

sudo -u www-data /var/www/cacti/scripts/nextcloud_auditlog.sh -n
Login_UnknownUser:6 FileAccess_UnknownUser:0 FileWritten_UnknownUser:0 FileCreated_UnknownUser:0 FileDeleted_UnknownUser:0 New_Share_UnknownUser:0 Share_access_UnknownUser:0 Preview_access_UnknownUser:0

Syntax is nextcloud-auditlog.sh -h?Hv <user>

    -h, or ? for this help
    -H  will generate Human output
    -c  will generate clean output with only valid data
    -n  will generate information about nonregistered users, e.g. CLI User, or user trying to login with wrong name, etc.
    <user> will generate output only for a particular user. Default - all users will be fetched from the nextcloud

TODO Adjust for common config file and set limit to the users amount.

If you have antivirus installed, then try it. Perform nextcloud.log analyze and send notification to any user. Made to avoid this Issue.

This script will search all duplicates in user folder and tag them with corresponding tag. Configuration:

tagName=duplicate Tag Name to set on duplicates. Should be exist in system (at least 1 file being tagged with this tag)

NextcloudURL="https://yourFQDN/nextcloud" Nextcloud URL to perform API calls

User="user" Username

password="xxxxx-xxxxx-xxxxxx" Password, please create application password under .../index.php/settings/user/security

LogLvL=Info Log Level could be: none|Info

NextCloudPath=/var/www/nextcloud Path to nextcloud Folder. Data folder will be retrieved automatically from the config file.

Performs External Shares rescan only that will save a lot of time in compare to scan whole nextcloud. Basically, it works out from the box. Only that you must check you nextcloud path, log path and create a log file for php occ output. Will do external ONLY shares rescan for nextcloud.

Run it under nextcloud user (for me it is www-data) basically twice per day at 2:30 and 14:30. You can run it also hourly. This is my cron config (for more cron examples, please refer to manpages):

30 2,14 * * * perl -e 'sleep int(rand(1800))' && /usr/local/bin/nextcloud-file-sync.sh #Nextcloud file sync

Here I add perl -e 'sleep int(rand(1800))' to inject some random start time within 30 Minutes, but since it scans externals only it is not necessary anymore. Your cron job config to run it hourly could be simple:

@hourly /usr/local/bin/nextcloud-file-sync.sh

If you would like to perform WHOLE nextcloud re-scan, please add -all to command, e.g.:

sudo -u www-data ./nextcloud-file-sync.sh -all

Will generate NC log output:

I have had some issues (like described here https://help.nextcloud.com/t/occ-files-cleanup-does-it-delete-the-db-table-entries-of-the-missing-files/20253) in older NC versions, so I added workaround from line 60 till 67 as files:cleanup command, nut sure if it is needed now, but it does not harm anything.

This script will read Nextcloud Activity RSS via API call and push them to Gotify server. If you do not see any new activities, try to delete lock file, specified in LOCKFILE

Please create Application password for this script.

This script will read Nextcloud Notifications via API call and push them to Gotify server. If you do not see any notifications, try to delete lock file, specified in LOCKFILE

Please create Application password for this script.

In Gotify Server you have to create an Application and provide API Token to script.

There are 2 modes: push and sync.

• In case of push Notifications from Nextcloud will be pushed to Gotify if you delete notification in Nextcloud or Gotify there will be no reaction.
• In case of sync you will have synced notifications stage between both Nextcloud and Gotify, Notification delete in Gotify will cause deletion of this Notification in Nextcloud and opposite. In Gotify Server you must create a Client Token and provide it to script additionally.

In order to reduce HDD space being used, this script will create hardlinks to duplicated files together with rdfind.

This script avoids parallel Preview Jobs and write execution time to the logs.

Since last update, Application will detect if it is already run and will not be executed twice/parallel (https://help.nextcloud.com/t/clarity-on-the-crontab-settings-for-the-preview-generator-app/6144/54), so you can add it e.g. to execute each 20 Minutes as cron job directly. This means that nextcloud-preview.sh is not needed anymore, only make sense if you would like to have execution information directly in nextcloud logs.

Will generate NC log output:

This script will do backup of Nextcloud folders via RSYNC to remote machine with SSH Key authentication. You can edit key --exclude=FolderToExclude to exclude folders such as:

• data/appdata*/preview exclude Previews - they could be newly generated,
• data/*/files_trashbin/ exclude users trash-bins,
• data/*/files_versions/ exclude users files Versions,
• data/updater* exclude updater backups and downloads,
• *.ocTransferId*.part exclude partly uploaded data from backup.

Or you can even combine and do rsync into archive (with remote authentication via SSH Key) if you set CompressToArchive=true.

As per this tread I added simple script that will do check if updates or reboot is required and show it as NC notification. Works on Ubuntu 16.04+.

You only must specify user from the Administrator group to get notifications via USER="admin"

This script works with https://apps.nextcloud.com/apps/user_usage_report

Will generate report and output it in cacti format. Supports Argument as "user" if you need to check statistic for one user only run ./nextcloud-usage_report.sh user to get specific user information. AS-IS without any warranty. Output fields are:

storage_all, storage_used, shares_new, files_all, files_new, files_read

This script work as a Talk Chat bot. Will return you useful links specified in nextcloud-links-list. To add bot simply execute:

sudo -u www-data php /var/www/nextcloud/occ talk:command:add links links "/usr/local/bin/nextcloud-bot-links.sh {ARGUMENTS} {USER}" 2 3

More information about is under https://nextcloud-talk.readthedocs.io/en/latest/commands/

In a code, please specify absolute link to the nextcloud-links-list as list, e.g.:

list="/usr/local/bin/nextcloud_links_list"

Output example:

/links git
Hey,  here is something useful for you:
Your git is under https://domain/git

Known Bug/Feature: it will return all lines with matched words, e.g. if you are typing /links Your, you will get whole list from example below.

This is a list of useful Links or other Info for a Talk Chat bot. Simply one line per output. E.g.:

Your wiki is under https://domain/wiki
Your git is under https://domain/git
Your notes are under https://domain/index.php/apps/notes

Basically, you can put in this list whatever to be shown as one line per request.

This script work as a Talk Chat bot. Will return you (girls) rate from 1 till 10. To add bot simply execute:

More information about is under https://nextcloud-talk.readthedocs.io/en/latest/commands/

Output example:

/rate
