: this is what i tryed on the command prompt.
:
: perl -pi -e 's{^<!--\n<td>}{test}' hello.txt
:
: but this command is not working .. so anybody kindly please help me in getting a
:regular expression for this.
Two things:
1. The -p flag by itself will only read in one line of hello.txt at a time.
Use -0777 (that's "dash zero" followed by 777) to make perl slurp up the whole
file as a single string.
2. Use the "s" modifier to treat the slurped-up file as a single string.
So the command would look like this:
perl -0777 -pi -e 's{^<!--\n<td>}{test}s' hello.txt
(I would also change -i to -i.bak so you have a backup copy of the
original file.)
