get a substring with a bash command
 

Hi,

i've a file that has the following content:

<param>1</param>
<param>2</param>
<param>3</param>
...
<param>n</param>

I want to use a bash command that put to the output only the values:
1
2
3
...
n

How is this possible?

Thanks,
Pedro

Thanks, for the answer.
And, which bash command should i use to remove the spaces from the beginning of each line?

Thanks,
Pedro

sed 's/^ *//g' file
to see output

sed -i.bak 's/^ *//g' file
to edit file in place and make backup

Thanks for the aswner
