Hi. I have a file with asterisk field separators and backslash line terminators. The first field in each line names the line type. I am trying to process each range separately. Here's what the data looks like:
So what I want do is get the ranges of text between LS and LE. Then with each range I want replace the '00020' occurrences with a number that is increased each iteration. So on the first pass '00020' is changed to '1' then on the next range 00020 is changed to '2'. Here's how the data should look after processing:
I can get the ranges with this using sed and awk:
Since I want to work with the range of data I can't just process it line by line because I need to update the range of data. Everything seems to treat the ranges as one big range. I am trying to learn perl too so I thought maybe I could use perl but I don't know how to put a multi-lined string into a perl array. If anyone has any suggestions as to what would be the best approach I would be very grateful.
Can I use search & replace in any variable?
Suppose I have one variable named var1 which holds value "abcabc" I need to search 'a' in var1 and want to replace with 'x' like 'xbcxbc'. Is it possible? Can you provide me an example?

diff3
diff3(1) General Commands Manual diff3(1)NAME
diff3 - 3-way differential file comparison
SYNOPSIS
file1 file2 file3
DESCRIPTION
compares three versions of a file, and prints disagreeing ranges of text flagged with these codes:
all three files differ
file1 is different
file2 is different
file3 is different
The type of change required to convert a given range of a given file to some other is indicated in one of these ways:
Text is to be appended after line number
n1 in file f, where f = or
Text is to be changed in the range line
n1 through line n2. If n1 = n2, the range can be abbreviated to n1.
The original contents of the range follows immediately after a indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
Produces a script for the
editor that can be used to incorporate into file1 all changes between file2 and file3 (see ed(1)); i.e., the changes that
normally would be flagged and
Produces a script to incorporate only changes flagged
Produces a script to incorporate only changes flagged
Produces a script that will incorporate all
changes between file2 and file3, but treat overlapping changes (that is, changes that would be flagged with in normal
listing) differently. The overlapping lines in both files will be inserted by the edit script bracketed by and lines.
Produces a script that will incorporate only changes flagged
, but treat these changes in the manner of option.
The following command applies the resulting script to file1.
