# Set inotify watch limit high enough for IntelliJ IDEA (PhpStorm, PyCharm, RubyMine, WebStorm).
# 1. Check current value in use: `cat /proc/sys/fs/inotify/max_user_watches`
# 2. Create this file as /etc/sysctl.d/60-jetbrains.conf (Debian, Ubuntu, Fedora...)
# 3. Apply new configuration: `sudo sysctl -p --system` or `sudo service procps start` or reboot
# 4. Check new value in use: `cat /proc/sys/fs/inotify/max_user_watches`

Backup android app, data included, no root needed, with adb

Note: This gist may be outdated, thanks to all contributors in comments.

adb is the Android CLI tool with which you can interact with your android device, from your PC

You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.

Don't hesitate to read comments, there is useful tips, thanks guys for this !
