Help with sed-script
Hi!

I really need some help and feedback with my sed-script below.

I want to find all HTML files and then remove everything before <body> and everything after </body>, including both tags. When the SED is done it should save the new content to a new file with the name "index.html_nobody" (just add "_nobody" to the filename).

The problem I got is "Syntax error: newline unexpected".

Theres a simple HTML page:
Code:
<!DOCTYPE html>
<html>
<body>

<img src="w3schools.jpg" alt="W3Schools.com" width="104" height="142">

</body>
</html>

The script should return only this line:
Code:
<img src="w3schools.jpg" alt="W3Schools.com" width="104" height="142">

Here's my script so far:

Code:
path="$1"

#!/bin/bash

find "$1" -type f -name "*.html" -o -name "*.htm" | while read -r filename; do
     echo -e "\nFound:\n""$files\n"

        if [ -e "$1" ]
then
                echo "Editing files"
                exec sh -c "$filename" | sed '0,/<body/ { /<body/! d ; /<body/ s/.*<body[^>]*>// } ; \|</body|,$ { \|</body|! d ; \|</body| s|</body.*|| }' ; > "{}_nobody"

else
        echo "File not found."
fi
done

You said:
Code:
exec sh -c "$filename" | sed ... etc...

I think you want to do your sed on the file, so either "cat" the file or use file as an argument to your sed.

Thank you cjcox!!

Now I have the saving problem. It won't save the file with the new filename.
If the original filename is index.html the new filename should be index.html_nobody.

I have the code > "{}_nobody" but it won't work...
It saves the file to be named exactly {}_nobody but with no content...

Change our output redirect to:
Code:
...... > "${filename}_nobody"

Your output sample does not fit your spec; according to the spec, there should be an empty line before and after the source line, respectively.

How about
Code:
sed -n '/body/,/\/body/ {/\/*body/d;p}' file > index.html_nobody

I got it all right now, but the output file is empty...

Code:
#!/bin/bash
path="$1"

find "$1" -type f -name "*.html" -o -name "*.htm" | while read -r filename; do
     echo -e "\nFound:\n""$filename\n"

	if [ -e "$1" ]
then
		echo "Editing files"
		cat "$filename" | sed '0,/<body/ { /<body/! d ; /<body/ s/.*<body[^>]*>// } ; \|</body|,$ { \|</body|! d ; \|</body| s|</body.*|| }' ; > "${filename}_nobody"

else
	echo "No files found."
fi
done

I got this output below, but it won't save it, just created a new file with correct filename but with no content...

Code:
Found:
/home/user1/test.html

Editing files

That semicolon ends the sed, which then prints to stdout, and starts a new command (just redirection), which creates a new file.
