Hi,

Sed will do it...

sed 's/test>\(.*\)<info/\1/g' file.txt

sed 's/test>\(.*\)<info/\1/' <file>

If you actually have a delimiter like ">" or "<", you could also use "cut":

In your example:
cut -d'>' -f2 file |cut -d'<' -f1

should do the trick too.

thanks a lot that works all apart from one problem it seems out output the text on the line after <info for example if i have

Code:

test>test1<info

test>test2<info(more info)

test>test3<info

it will out output

Code:

test1

test2(more info)

test3

is there a way to stop this ive worked out how to use
sed -n 's/test>\(.*\)<info/\1/gp' <file>
to filter out other lines but i cant seem to work this last part out

I went a step more and put some text in front also....

Code:

test>test1<info

here is some test>test2<info(more info)

test>test3<info

So, I used .* to indicate one or more characters before test> and after <info

Code:

sed 's/.*test>\(.*\)<info.*/\1/g' file.txt
