如何将html转换为一个行字符串？

I have some large templates as html:

<% /*   
  This is basically all the markup and interface
/* %>
<div id="test" class="test-right"></div>
  <div id="test" class="test-right"></div>

Which I need to have as one line string, for example:

<% /*
  This is basically all the markup and interface
*/ %>
<div id=\"test\" class=\"test-right\"></div>
   <div id=\"test\" class=\"test-right\"></div>

How can you do that?

original_string='test this id="one" test this id="two"'
string_to_replace_Suzi_with=\"
result_string="${original_string/"/$string_to_replace_Suzi_with}"

If you are looking for a pure bash way to do this, you can run them in command-line one at a time or in a script.

# Store the contents of the file into a variable
fileContents="$(<file)"

# Create a temporary string using 'GNU mktemp'
tempfile="$(mktemp)"

# Parameter substitution syntax to replace the new-line character by
# empty string and store it in the file identified by the temporary
# name
printf "%s
" "${fileContents//$'
'//}" > "$tempfile"

# Revert the temp file to original file
mv "$tempfile" file

But considering bash is slower for this trivial task, use Awk by restting the ORS from new-line to empty string,

awk -v ORS="" 1 file
<% /*     This is basically all the markup and interface/* %><div id="test" class="test-right"></div>  <div id="test" class="test-right"></div>

If you want to replace newlines (carriage return) by a litteral , you can use awk:

awk -v ORS='\
' 1 file

This will replace the output record separator ORS to a litteral . The 1 triggers the default action in awk, print the entire record.
