I am not looking for 4 different strings, each on it's own line. Grep -e, or egrep, would work fine for this.
I am searching for these 4 lines, together, when they appear back to back.
In order for the condition to be true, all 4 lines must exist, exactly as seen below.
In the pattern match, I need to search for something like this:
Code:
sed -e s/"abc\ndef\nghi\njkl\n"/""/g
I also tried:
Code:
sed -e s/"abc\rdef\rghi\rjkl\r"/""/g
I also thought about using "tr" to delete the matching strings, but I'm still having an issue matching the 4 lines, to include their special characters. i.e. Line Feeds or Carriage Returns.
Unfortunately, either I'm using the wrong carriage return characters, or something is wrong with my systax.
Basically, each time the above 4 lines occur, back to back, on separate lines, I need to remove all 4 lines.
There will be times when the 4 lines will appear, where they have some other entries in the middle, such as:
Code:
abc
e2c422 a12652
def
ghi
jkl
Note that if there are ANY characters or data of any kind between, or in the middle of the 4 line pattern, those are valid data lines, and must not be removed.
Only when the 4 lines appear, back to back, with NOTHING else between them, or appended to them, do they need to be removed.
I hope this helps to clarify the issue.

GREP(1) General Commands Manual GREP(1)NAME
grep, g - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
g [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines that match the pattern, a regular expression as defined in regexp(7) with
the addition of a newline character as an alternative (substitute for |) with lowest precedence. Normally, each line matching the pattern
is `selected', and each selected line is copied to the standard output. The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-e The following argument is taken as a pattern. This option makes it easy to specify patterns that might confuse argument parsing,
such as -n.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
-f The pattern argument is the name of a file containing regular expressions one per line.
-b Don't buffer the output: write each output line as soon as it is discovered.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'. An expression starting with '*' will treat the rest of the expression as literal characters.
G invokes grep with -n and forces tagging of output lines by file name. If no files are listed, it searches all files matching
*.C *.b *.c *.h *.m *.cc *.java *.cgi *.pl *.py *.tex *.ms
