egrep "| N1" and "| N2" and "| N3" from file 1

[littleIdiot]

Hi,

Simply really ... I have a pipe delimited text file and want to grep everything except the following text:

| N1
| N2
| N3
| N4
| N5
| N6
| N7
| N8
| N9

I have searched the FAQ's and this forum, but not really getting anywhere.

I think egrep and an input file listing my text will work, so I have a file as above called strings.txt but the following fails:

egrep -e strings.txt pipe_delim.txt

any ideas?

egrep -[!]f[/!] strings.txt pipe_delim.txt

Hope This Helps, PH.

Thanks - but no joy ...

% more strings2.txt
| N1
| N2
| N3
| N4
| N5
| N6
| N7
| N8
| N9
% egrep -f strings.txt pip_delim.txt
egrep: syntax error
%

sorry - strings2.txt should be strings.txt

I have tried it with

"| N1"
and
| N1

You may try this:
\| N1
...

Ah ha - that works ...

egrep "\| N1|\| N2" pipe_delim.txt

Many thanks (yet again) to PHV

Try :

fgrep -f strings.txt pipe_delim.txt

Another way:
grep '| N[1-9]' pipe_delim.txt
