how to retrieve the word between 2 specific words with shell script
Hi,

I have a file content like:

Code:
:
:
<span class="ColorRed"> 1.23</span><br>
:
:

the value 1.23 will be changed from time to time, and I want to use a shell script command, e.g grep or sed, to retrieve only the value, how to do it?

Thanks!
Victor

Hi,

Thanks a lot...

Can I have a further question, how to do that if the content looks like:

Code:
:
:
<span class="ColorRed"><img src="https://www.unix.com/../common/images/arrow_red_L.gif" width="26" height="26"> 1.23</span><br>

It would be better if you showed more contents from your inputfile...
but check this now...
Code:
sed 's/.*\>\( [0-9|.]*\)\<.*/\1/g' infile

generic, to remove '<>' tags
Code:
sed 's/<[^>]*>//g'

I don't think that's the requirement...

Code:
sed 's/.*\>\( [0-9|.]*\)\<.*/\1/g' infile
