Pattern in a paragraph
Hi,
I have read similar questions and I was not able to get a solution, so please help
I have two files:
1-Pattern file contains list of patterns
pattern1
pattern2
pattern3
pattern4
....
pattern#
2-input file in the format
>hdhfshsdfjhpattern1xmbxmbxnmv
bzxnxnbnccm,nvbnmvbnvvn,v,v,v
ncxnmvbnmvbnvvnnv
>vnbnmcbvn,mx,fmf,mnxvm,nv,mnv
nxnvnv,mcn,vn,
>pattern3mmdlskfjkd
nxmnxm,nvmnv
I am trying to remove the line with matching pattern plus the following lines. I have this solution, that will delete the pattern and next line but not the whole record
for keyword in `cat pattern.txt`; do sed -i -e '/'$keyword'./N/d' input.txt; done
Thanks,

NAME
copt - peephole optimizer
SYSNOPIS
copt file ...
DESCRIPTION
copt is a general-purpose peephole optimizer. It reads code from its standard input and writes an improved version to its standard output.
copy reads the named files for its optimizations, which are encoded as follows:
<pattern for input line 1>
<pattern for input line 2>
...
<pattern for input line n>
=
<pattern for output line 1>
<pattern for output line 2>
...
<pattern for output line m>
<blank line>
Pattern matching uses literal string comparison, with one exception: ``%%'' matches the ``%'' character, and ``%'' followed by a digit
matches everything up to the next occurrence of the next pattern character, though all occurrences of %n must denote the same string. For
example, the pattern ``%1=%1.'' matches exactly those strings that begin with a string X, followed by a ``='' (the first), followed by a
second occurrence of X, followed by a period. In this way, the input/output pattern
mov $%1,r%2
mov *r%2,r%2
=
mov %1,r%2
commands copt to replace runs like
mov $_a,r3
mov *r3,r3
with
mov _a,r3
Note that a tab or newline can terminate a %n variable.
copt compares each run of input patterns with the current input instruction and its predecessors. If no match is found, it advances to the
next input instruction and tries again. Otherwise, it replaces the input instructions with the corresponding output patterns, pattern vari-
ables instantiated,and resumes its search with the first instruction of the replacement. copt matches input patterns in reverse order to
cascade optimizations without backing up.
BUGS
Errors in optimization files are always possible.
