Thank You!

Can anyone tell me what this error means?:

Usage: grep -hblcnsviw pattern file . . .

Thanks in advance!

Solved it.

This will work if anyone else has the same problem:

sed -n -e H -e '${' -e g -e 's/--#\n/newline \
/2' -e p -e \} file > newfile

Ok,
Ive found out what I need to do, I need to expand the pattern space to include the entire file (not just one line), then search for the nth occurence of '--#'.

Does anyone know how to do...

Oh I see, it works if I change the number to 9 (The line number of the second '--#'.

But I have many files and the 2nd occurnce of '--#' occurs on different lines in each file.

Is there anyway...

Thank you, that works on the first occurence if i change the 2 at the start to a 1, but it doesnt work on the 2nd occurence if it is left as a 2!

Im not sure why!

Thanks that worked great!

Is there any method of apply this to only the second line containing only '--#' and leaving the first line the same?

Thanks for your help!

Hi,

I have the following file:

--#
--#line1
--#line2
--#line3
--#
--#line4
--#line5

and I want to use something like:

sed 's/--#/newline/g' file > newfile

to substitute the lines...

Sorry, I just wasnt sure if it was a beginners problem or an advanced problem!
Wont do it in the future!

I have a file like this:

--#
--#line1
--#line2
--#line3
--#line4
--#line5

--#
line6
line7
etc...

I want to insert a line before the second occurence of '--#' on its own.
eg I want...

I have a file which looks something like this:

--#
--#line1
--#line2
--#line3
--#line4
--#line5
--#line6

--#
line7
line8
line9
.........and so on


Id like to insert a line (2...

Its ok, I sorted it in the end!

For anyone else with the same problem, you dont need to change the first 2 delimiters, only the ones after the s! The following code works!

code:
sed...

Thats great!
How would it be used if i wanted the first line somewhere in the middle of the rest of the line eg:

input:
line1
line2
line3

output:
line1
create|vt|line1...

Ok im stuck on the same command again!
I want to put a filename after each of the lines, but the filename obviously contains '/' so I need to use a different delimiter, but when I change:

sed...

Thank you for that, it works perfectly!
Uve saved me sooo much time!
Cheers!

Thanks for the reply, but I cant get that to work!
I was looking for a method which i dont need to type each line out because I need to run it on a file with 800 lines and I want it to do the same...

Thanks for the reply, but i tried it and it said:
sed: illegal option -- r

so I removed the -r and it said:
sed: command garbled: s/^(.*)$/\1new\n\1newline\n/

I dont understand why!

Sorry if im being stupid, but what would the code be if you wanted to add a third (or more) line to each line of original code? (each new line may contain the original line)

Thanks,
Dave

The first one worked, thank you for all your help!

Yeah it definately is!
I copied your code exactly.
Ive been looking around and there are a few people with the same problem, apparently \n doesnt work on some versions of UNIX.
Do you know of any...

Yeah thats exactly what I want!
But for some reason, when I run it, i get:

file:
line1
line2
line3

cat file|sed 's/\(.*\)/\nextra\1/'>newfile

cat newfile:
nextraline1
nextraline2...

Thanks, that works for the first line, but i want to create a second line with the first line in it. And the following code doesnt work.

sed -e 's/\(.*\)/\1\nextra\1/' -e '/\(.*\)/ a\\...

I would like to change the lines:
originalline1
originalline2

to:
originalline1new
originalline1newline

originalline2new
originalline2newline

To do this, id like to combine the...

Im trying to replace every line

line1
line2
line3

with:

line1
extraline1

line2
extraline2

line3
extraline3


with about 10 extra lines
I am able to add axtra lines with:
