概念澄清与总体思路
用 Linux 做竞品分析的可行路径
实战流程示例
场景A:批量提取对手发布包或素材的元数据
mkdir -p out && echo "file,type,keyword" > out/meta.csv
for f in **/*.(jpg|jpeg|png|pdf|mp3|ogg|zip); do
type=$(file --brief --mime-type "$f")
echo -n "\"$f\",$type," >> out/meta.csv
extract -x comment -p comment "$f" 2>/dev/null | tr '\n' ';' | sed 's/;$//' >> out/meta.csv
done
cut -d',' -f3 out/meta.csv | tr ';' '\n' | sort | uniq -c | sort -nr | head
场景B:抓取并分析对手的榜单/页面内容
curl -s "https://example.com/rank?start=0&num=24" | \
grep -oP 'href="/app/\d+">' | sed 's/.*href="//;s/">//' | \
while read id; do
curl -s "https://example.com/app/$id" | \
grep -oP 'class="title">\K[^<]+' | head -1
done > top_titles.txt
