GREP or similar to update my files?

[Dungeon]

One of my client's web site has hundreds of HTML pages with the same bad template. Therefore all the pages have the exact same typo. One of the options is to download all the html pages, do a find & replace (Gsar is perfect for this job on Windows platform) then upload them back. But it's kinda hassle. Is there any way to do a GREP on the server directly so I can do find&replace easily?

Raise a trouble ticket.

If you provide the exact details to the support team, I'm sure it would be possible if a global search and replace is all that is needed. (Can't promise, I'm not the support team and don't know how busy they are with priority issues, but no harm in asking.)

(Alternatively, you could do it via php, but this would be long winded!)

Nevermind. For now, I did using the long way (DL/UL)

That would be nice if I could use awk or some similar linux command at crontab.
