add word to each line of the file?

If I want to insert a word into the beginning of each line in a file do I use the command "paste"?

from

is a test
is a test2
is a test3

to

this is a test
this is a test2
this is a test3

if so whats the format?

I would use sed instead...

Code:

$ cat file
is a test
is a test2
is a test3
$ cat file | sed -e 's/is/this is/g' >> file2
$ cat file2
this is a test
this is a test2
this is a test3

Paste will combine the lines of two files, separated by a tab.

Or for the same file "sed -i -e 's/is/this is/' filename"
The "g" would add "this" to all words "is" in a line.

Your right makuyl, good catch...

hi there,

just to contribute:
if your line does not share the same pattern you can use ^

Code:

sed "s/^/this /g" your_file
