HTML itself is just plain text, there aren't any tags that run operations
on the server like including a file's contents into the page.
Depending on where you're hosting you could use CGI, Server Side Includes,
PHP, or any number of other language options to do the job.
If you want to use a shell script, with no template, you could try
something like this:
Step 1: Enclose the md5 sum with <span> tags and an ID you can use to find
it. <span id='progmd5'>705e7980394e597ade51f8ccd2cbfe20 MyProgram.exe</span>
Script option 1 -- inline md5sum:
perl -p -i -e "s|(<span id='progmd5'>).*?(</span>)|\${1}`md5sum
MyProgram.exe`\${2}|" output.html
Script option 2 -- md5sum in variable
PROGRAM_MD5=`md5sum test.html`
perl -p -i -e "s|(<span id='progmd5'>).*?(</span>)|\${1}$PROGRAM_MD5\${2}|"
output.html
The above regex assumes that the start and end span tags are on the same
line.
