I'm trying (desperately) to find a "pre-canned" script that will take an html file and replace each reference to a .jpg file with the name of a .jpg file within the directory we are running the script (same one that contains the html file).

To be more clear, I have a monthly webpage with pictures of my newborn. The page has 24 jpg thumbnails which link to the large version of their respective picture. All 48 pictures, as well as the html file, are all in the same, unique directory. All of the thumbnails filenames end with .SMALL.THUMB.jpg and all of the larger size have the same name, but end only in .SMALL.jpg

So, is there some way to have a script just change all the old jpg references to match the current files in the directory, and do them in a way as to ensure that the thumbnails point to the correct picture? The thumb and the respective larger pic both have the same name, of course, with the addition of .THUMB on the thumbnail...

Oh, and I apologize, but I have no experience writing scripts. I'm running Mandrake 10, if that makes any difference. If you need any other info, please ask. I'll get back to you immediately.

Please help!

Thanks to you all!!!!!

Thank goodness for L.Q......

using your text editor, can't you just do a find/replace?

yeah, but seeing as I have a newborn, I'm using the excuse that I'm really busy and it takes too long to do by hand....

Perhaps it's just laziness, or a yearning for proficiency, but I'm getting tired of copy/pasitng the old names over the new. They're all different names (for each pair of thumbnail/larger image), so search and replace really only adds the step of typing in the OLD filename, whereas right now I just pipe "ls -l" in the directory to a text file and copy the filenames of the new images from there to the html file. It gets old.....

Please help....

perl -ep 's/onething/foranother; print;' << file

Don't I need to somehow have the script create a variable, read the names of the files in the current directory, and assign them sequentially to the variable as it changes each file name?

THe above looks to me as though I have to type in the old filename, then the / and then the new filename, which isn't really what I'm looking for...

Thanks so far though...

If your sed is >= 4.x :)


If it's an older version

Cheers,

That's what I'm taling about!!!

Thanks Tink!

I haven't done it yet, as I have one question. Is there somewhere in that line that I need to name the file that's it's editing? For instance, nine_months.html? Or is it just going to edit the only text file in the working directory?

*points at $file in Tink's example*

That's where you put your filename.

In my script it would modify every file it comes across...

to change that you need to modify the ls-statement in

for file in `ls -1`;

to

e.g.

for file in `ls -1 *months*html`;

I'm sorry, I'm usually not this much trouble. THANK YOU for getting me this far...

Here's what I deduced this should look like:

for file in `ls -1 *months*html`; do sed -i 's/small/SMALL/g' $file ; done

And nothing seems to have changed. Just for clarification, here's the contents of the current directory:

So again, I'm trying to replace the names of the jpeg references in the ten_months.html (which are names not seen in this directory) with the names you see above.

Nothing seems to have changed after I did the code above...

Any ideas what I'm doing wrong?

Thanks again

What does that -i do exactly?

I don't know what to say :)

If you edit a html file - what change (except for the obvious
in the time-stamp) do you expect to see in the directory listing?

As for my replacement string, that was also just taken from the
example in the perl command.
You obviously need to change that to whatever you're REALLY
trying to achieve (I wasn't quite sure from the original post - you
referred to large as opposed to old, and I wasn't sure what you
meant ;}).

Tink

Read
man sed

Sorry, I'm probably a bit spolied, as I expected to be able to just "copy/paste" your example without major modifications.

The old vs large etc thing was just as follows, and in retrospect I really should have given an example of the html code I'm looking to edit with this effort...

################################html code#####################################################

################################end cose#######################################################

So, I need to replace every filename (old files) you see after an occurance of 10_months/ (in the code above) with the filenames of the images in the directory listing, and hopefully get them to line up so that each <a href="xxxxx.SMALL.THUMB.jpg"> point to the correct <img src="xxxxx.SMALL.jpg">. The above code repeats 4 more times, so copy/pasting this manually takes a few and it makes me procrastinate doing it, so I'm trying to speed this up. Plus, this will really help me start to teach myself this kind of stuff, as I'm still considering myself a newbie to the linux world....and lovin it....

Seriously, I appreciate your patience and help...

Jeff

But in terms of the file-names I still don't know
(or couldn't figure out, whatever) what is the
old filename, and what you want to change it to.

Or, in other words, can you give me a before/after
scenario of one line of hrf /imgsrc combos?

Tink
