# automating my gemlog index on sdf

so this iis the second post and I have updated my script to update the gemlog.
 
```
cat << 'EOF' > update-gemlog.sh
#!/bin/bash

GEMLOG_DIR="gemlog"
INDEX_FILE="${GEMLOG_DIR}/index.gmi"



# Write Header
cat << 'HEADER' > "$INDEX_FILE"
# Field Notes & Gemlog

Welcome to my log. Entries are listed in reverse chronological order.

HEADER

# Find all .gmi files except index.gmi, extract title or filename, and sort reverse-chronologically
for file in $(ls -r ${GEMLOG_DIR}/*.gmi 2>/dev/null); do
    basename=$(basename "$file")
    
    # Skip the index itself
    if [ "$basename" = "index.gmi" ]; then
        continue
    fi

    # Read the first heading (# Title) or fall back to filename
    title=$(grep -m 1 "^# " "$file" | sed 's/^# //')
    if [ -z "$title" ]; then
        title="$basename"
    fi

    echo "=> ${basename} ${title}" >> "$INDEX_FILE"
done

# Write Footer
cat << 'FOOTER' >> "$INDEX_FILE"

=> / Back to main capsule
FOOTER

echo "Gemlog index updated successfully!"
EOF
