/etc/environment output
Code:
# START KALI-DEFAULTS CONFIG
# Everything from here and until STOP KALI-DEFAULTS CONFIG
# was installed by the kali-defaults package, and it will
# be removed if ever the kali-defaults package is removed.
# If you want to disable a line, please do NOT remove it,
# as it would be added back when kali-defaults is upgraded.
# Instead, comment the line out, and your change will be
# preserved across upgrades.
