# Script for removing emails, IPs, and other sensitive info from log files.

if [ $# -eq 0 ]; then
    echo "Usage: $0 [-i] [file ...]"
    exit 1
fi

# Extended, case-insensitive regex patterns for things you want to remove
sanitize=(
	"Martin"
	"mhebes"
	"mywindowsusername"
	"C:"
	"D:"
	"My Server's Friendly Name"
	"The Name of The Movie( \(2004\))?"
)

# Create replacement pattern from array
pat=""
for i in ${!sanitize[@]}; do
	pat="${pat};s/${sanitize[$i]}/[REDACTED]/gi"
done

# 1. Replaces emails with MYEMAIL@example.com
# 2. Replace the first two octects for IP addresses with XXX's (e.g. 192.168.1.50 -> XXX.XXX.1.50)
# 3. Replaces anything in the sanitize list with [REDACTED]
