Insert text at the beginning of every line of a log file.

[Adam Prince]

G'day all,
I have a logfile and I would like to insert text and the beginning of every line. I am pretty sure I use sed but I can seem to get the syntax right. Any help would be greatly appericated. Merry Xmas to all.

Hi,

try this:

sed -e 's/^/your_text/' file > file1

Hi Adam,

With perl, you can also do an in-line edit:

perl -pi -e 'print "your_text"' logfile

Rgds, Robin.

# sed 's/^/hello /g' fileA > fileB

==> will insert text "hello "

Andreas answer is better than the a append or i insert options of sed. I would go with that sed option for easy of use.
