Replacing text in between the string
Here is just a few variations that follow the same principle. We need to update the path to all images (only images)

Code:
<IMG src="/3251_8832613.jpg">
<IMG src="https://www.unix.com/images/1303_4703925.jpg">
<IMG src="\\SERVER\DATA\Image\1948_4703925.jpg">
<img src="\\SERVER\STORE\image\2721_7990660.jpg">
<IMG style="HEIGHT: 3.5in" src="\\server\data\image\90417_4302013100410.jpg">
<IMG style="HEIGHT: 3.5in" src="\\10.10.10.10\data\image\90417_4302013100411.jpg">
<IMG style="WIDTH: 434px; HEIGHT: 369px" height=433 src="/2360_7990660.jpg" width=438>
<IMG style="WIDTH: 3.5in" src="https://66.66.66.66/images/5942_7990660.jpg">

The goal is to identify anything between <IMG .* > and replace the source path for the images src="" until there is a / or \ to this type of output, leaving actual filename in tact, only uniforming the path to where they are located.

Code:
<IMG src="https://www.unix.com/images/3251_8832613.jpg">
<IMG src="https://www.unix.com/images/1303_4703925.jpg">
<img src="https://www.unix.com/images/1948_4703925.jpg">
<img src="https://www.unix.com/images/2721_7990660.jpg">
<IMG style="HEIGHT: 3.5in" src="https://www.unix.com/images/90417_4302013100410.jpg">
<IMG style="HEIGHT: 3.5in" src="https://www.unix.com/images/90417_4302013100411.jpg">
<IMG style="WIDTH: 434px; HEIGHT: 369px" height=433 src="https://www.unix.com/images/2360_7990660.jpg" width=438>
<IMG style="WIDTH: 3.5in" src="https://www.unix.com/images/5942_7990660.jpg">

Thanks in advance as I've been out of ideas on how to get this pattern in awk, sed, grep...

Try:
Code:
sed 'sXsrc=".*[\\/]Xsrc="https://www.unix.com/images/X' file

Don,

it almost worked, however there are some paths like this that actually got completely removed:

Code:
<IMG src="/2531_4703925.jpg"><BR><IMG src="/2531_7990660.jpg"><BR></P>

After running sed above:


Code:
<P><IMG src = " images/P>


P.S. argh why does it replace the images/p with this: "https://www.unix.com/images/P ? I've tried to edit this post few times already. this time adding spaces after src = and "

Try this:
Code:
sed '/^<[Ii][Mm][Gg]/sXsrc="[!"]*[\\/]Xsrc="https://www.unix.com/images/Xg' file

When file contains:
Code:
<IMG src="/3251_8832613.jpg">
<IMG src="https://www.unix.com/images/1303_4703925.jpg">
<IMG src="\\SERVER\DATA\Image\1948_4703925.jpg">
<img src="\\SERVER\STORE\image\2721_7990660.jpg">
<IMG style="HEIGHT: 3.5in" src="\\server\data\image\90417_4302013100410.jpg">
<IMG style="HEIGHT: 3.5in" src="\\10.10.10.10\data\image\90417_4302013100411.jpg">
<IMG style="WIDTH: 434px; HEIGHT: 369px" height=433 src="/2360_7990660.jpg" width=438>
<IMG style="WIDTH: 3.5in" src="https://66.66.66.66/images/5942_7990660.jpg">
<IMG src="/2531_4703925.jpg"><BR><IMG src="/2531_7990660.jpg"><BR></P

the output produced is:
Code:
<IMG src="https://www.unix.com/images/3251_8832613.jpg">
<IMG src="https://www.unix.com/images/1303_4703925.jpg">

<img src="https://www.unix.com/images/\SERVER\STORE\image\2721_7990660.jpg">
<IMG style="HEIGHT: 3.5in" src="https://www.unix.com/images/\server\data\image\90417_4302013100410.jpg">
<IMG style="HEIGHT: 3.5in" src="https://www.unix.com/images/\10.10.10.10\data\image\90417_4302013100411.jpg">
<IMG style="WIDTH: 434px; HEIGHT: 369px" height=433 src="https://www.unix.com/images/2360_7990660.jpg" width=438>
<IMG style="WIDTH: 3.5in" src="https://66.66.66.66/images/5942_7990660.jpg">
<IMG src="https://www.unix.com/images/2531_4703925.jpg"><BR><IMG src="https://www.unix.com/images/2531_7990660.jpg"><BR></P>

If you don't show us a representative sample of your input when you start, it should not be a surprise if input in a different format doesn't work with the solutions we suggest. Smilie

Thanks Don, but even in your output I don't see it correctly Smilie

Code:
<IMG src="https://www.unix.com/images/\SERVER\DATA\Image\1948_4703925.jpg">

It misses multiple paths... argh... I thought we were so close Smilie

Sorry, I had a typo. Try:
Code:
sed '/^<[Ii][Mm][Gg]/sXsrc="[^"]*[\\/]Xsrc="https://www.unix.com/images/Xg' file

producing the output:

<IMG src="https://www.unix.com/images/1303_4703925.jpg">

Hmm, I can't get latest regex to trigger at all on my data Smilie

Code:
$ sed '/^<[Ii][Mm][Gg]/sXsrc="[!"]*[\\/]Xsrc="https://www.unix.com/images/Xg' input > output
$ diff input output
$

tried with your latest one:

Code:
$ sed '/^<[Ii][Mm][Gg]/sXsrc="[^"]*[\\/]Xsrc="https://www.unix.com/images/Xg' input > output
$ diff input output
$

first script worked and had replaced, however this one for some reason does not eve trigger. I checked for the entries and yes, I do have them:

Code:
egrep "3251_8832613.jpg" input -c
5

here is few returns from the input file:
Code:
<IMG src="/3251_8832613.jpg">
<IMG style="HEIGHT: 3.5in" src="R:\Image\3251_8832613.jpg">

---------- Post updated at 09:29 PM ---------- Previous update was at 09:26 PM ----------

arghh, it was the ^ as my input file has a a lot more text before and ater, testing now data integrity Smilie

knock knock!
