IP-Extractor

ip-extractor.sh is a Bash script designed to extract IP addresses from any text input via the nano editor. It processes the input, saves clean IP lists into several formats, and provides immediate feedback in the console.

---

📦 Prerequisites

• Bash-compatible environment (Linux, macOS, WSL, etc.)
• nano editor installed
• Standard Unix tools: grep, sort, tr, cat, rm, sed, etc.

---

🚀 Usage

1. Run the script:

   ./ip-extractor.sh

2. On first run, a file called load will be opened in nano. Paste your raw text (e.g., log files, traceroutes, firewall logs).

3. Save and exit (Ctrl + O, Enter, Ctrl + X).

4. The script will:

   • Extract all non-localhost IPv4 addresses
   • Save them to a file called hosts
   • Remove duplicates
   • Create two additional files:
     • hostcom: IPs in a comma-separated format
     • chost: IPs in a space-separated format
   • Display the final list of IPs in console
   • Inform how many IPs were found

📁 Output Files

File	Description
hosts	Unique extracted IP addresses, one per line
hostcom	Same IPs as in hosts, comma-separated
chost	Same IPs as in hosts, space-separated
load	Temporary input file (deleted after run)
loadlast	Copy of last processed input

---

🛠 Features

• Clean parsing: skips 127.*.*.* and non-IP lines
• Visual feedback (▓, Done!) during processing
• Duplicate removal via sort -u
• Auto-relaunches itself if load file is empty or missing
• Multi-format output: plain, comma, and space-separated

---

🔁 Notes

• The script only works with IPv4 addresses.
• Edit the regex in grep if you want to support other formats or behaviours.
• You can comment or customise the JobFin messages for quieter output.
