I have a web page, say https://test.salesforce.com. I would like to search for a pattern, e.g. "src" at the beginning of a line in the entire webpage content. If the pattern is found, I need to retrieve that particular line which starts with the pattern and save it to a text file. I have tried curl and wget but I'm not getting proper output. So far i have tried the following

content=$(wget https://test.salesforce.com -q -O -)  
echo $content | grep -i src > test.txt

  • Please edit your original post and paste the exact command you've tried, preferably formatted as code. From what you've pasted here it's unclear whether this would even be executed properly. – Erathiel May 21 '15 at 17:33

Try something like

wget -qO- http://www.google.com/ | tr " " \\n | fgrep src= | tr \" \\n | fgrep -v src=

which will, however, output URLs as they are written in the file - which may be relative the the base URL.

  • Thank you for the response When i say web content, I would require only what showing in webpage, No properties or publisher details or anything like that. Is there any way we can get that ? – RRaju May 21 '15 at 18:36
  • In that case you need to analyse the whole tag, including stuff like <img and >. It is very helpful in these cases to know how the webpage code looks like (e.g. coming from the same source, like a CMS) to see where there are line breaks etc. If you need something which can apply to many web pages you need a more sophisticated SGML, XML and HTML5 parser. – Ned64 May 21 '15 at 18:45
