Get page titles from a list of URLS

I have list of URLS where I need to get the page titles saved in another list. wget or curl seems to be the right way, but I don't know exactly how. Can you help? Thanks

Solution

You mean something like that?

wget_title_from_filelist.sh

#!/bin/bash
while read -r URL; do
    echo -n "$URL --> "
    wget -q -O - "$URL" | \
       tr "\n" " " | \
       sed 's|.*<title>\([^<]*\).*</head>.*|\1|;s|^\s*||;s|\s*$||'
    echo
done

filelist.txt

explanation

tr "\n" " "     # remove \n, create one line of input for sed

sed 's|.*<title>\([^<]*\).*</head>.*|\1|;   # find <title> in <head>
s|^\s*||;                                   # remove leading spaces
s|\s*$||'                                   # remove trailing spaces
