특정 웹페이지의 현재 URL을 반환하는 bash 셸의 스크립트를 사용하려고 합니다... 내가 가진 것은 모든 URL을 반환하는 스크립트이지만 원하는 링크를 코드에 넣어야 합니다. 사용자가 단어를 입력한 다음 해당 단어가 포함된 모든 URL을 반환하도록 하려고 합니다. 이렇게 ./reddit.sh Linux하면 해당 단어가 포함된 URL이 표시됩니다. 이것은 지금까지 내 코드입니다.
wget -qO- http://reddit.com/ | grep -Eo "(http|https)://[a-zA-Z0-9./?=_-]*" | sort | unique

답변3
Reddit의 검색 결과(URL만)를 표시하고 API를 사용하지 않으려면 다음과 같이 하면 됩니다.
reddit() {
local 'search_term' 'user_agent'
user_agent='your_user_agent'
for search_term; do
curl \
--data-urlencode "q=${search_term}" \
--get \
--header "User-Agent: ${user_agent}" \
--silent \
"https://www.reddit.com/search" \
| grep -P -o -e '<a [^>]*? class="search-title may-blank" >.*?<\/a>' \
| grep -P -o -e '(?<=href=")(.*?)(?=")' \
| tail -n '+4'
done
}
