Apending word before each line in a file.

[ranjank]

Hi,

I have a file which continas 300 lines with each line starting with ".
e.g

"/var/opt/log"

I want to append a word before each line like :--

%dir %attr(0755,root,root)"/var/opt/log"

Can anyone give pointers on this.

With sed you may use ^ as a regular expression for the beginning of the line.

So to add the word 'newtext' at the beginning of every line:
sed -e 's/^/newtext/' input_file

Or to replace the word 'oldtext' by 'newtext', but only if it is at the beginning of a line:
sed -e 's/^oldtext/newtext/' input_file

hope this helps
