Your problem is the quotes:
The variable does not get expanded, because it's inside the single quotes, taken as literal. Turn the single quotes off and on:
and you should be good to go.
However this can be simplified quite a bit. All this perl stuff is not needed, since it only calls external tools (find, sed). You can do without:
The \x0a is a hex code of the newline char.
xargs will feed all the files to sed as arguments, so sed is actually called like:
Hi ,

Hi!
Considering below text, how would I use sed to insert text right below the v0005-line, using the SEPARATOR-line as a pattern to search for, so two lines above the separator? I can do it right above the separator, but not 2 lines...

match
MATCH(1L) Schily's USER COMMANDS MATCH(1L)NAME
match - searches for patterns in files
SYNOPSIS
match [ -option ] pattern [ file ... ]
DESCRIPTION
Match searches the named files or standard input (if no filenames are given) for the occurrences of the given pattern on each line. The
program accepts literal characters or special pattern matching characters. All lines that match the pattern are output on standard output.
You can only specify one pattern string for each match, however, you can construct an arbitrarily complex string. When you do not specify
a file, match can be used as a filter to display desired lines. Standard in is used if no files are specified.
OPTIONS -not, -v
Prints all lines that do not match.
-i Ignore the case of letters
-m Force not to use the magic mode
-w Search for pattern as a word
-x Display only those lines which match exactly
-c Display matching count for each file
-l Display name of each file which matches
-s Be silent indicate match in exit code
-h Do not display filenames
-n Precede matching lines with line number (with respect to the input file)
-b Precede matching lines with block number
REGULAR EXPRESSIONS
The following is a table of all the pattern matching characters:
c An ordinary character (not one of the special characters discussed below) is a one character regular expression that matches that
character.
c A backslash () followed by any special character is a one character regular expression that matches the special character itself.
The special characters are:
! # % * { } [ ] ? ^ $
! Logical OR as in match this!that!the_other. You may have to use `{}' for precedence grouping.
# A hash mark followed by any regular expression matches any number (including zero) occurrences of the regular expression.
? Matches exactly any one character. W? matches Wa, Wb, Wc, W1, W2, W3 ...
* Matches any number of any character.
% Matches exactly nothing. It can be used in groups of ored patterns to specify that an empty alternative is possible.
{} Curly brackets may be used to enclose patterns to specify a precedence grouping, and may be nested. {%!{test}}version matches the
strings testversion and version.
[string]
A non empty string of characters enclosed in square brackets is a one character regular expression that matches any one character in
that string. If however the first character of the string is a circumflex (^), the one character expression matches any character
which is not in the string. The ^ has this special meaning only if it occurs first in the string. The minus (-) may be used to indi-
cate a range of consecutive ASCII characters; for example, [0-9] is equivalent to any one of the digits. The - loses it's special
meaning if it occurs first (after an initial ^, if any) or last in the string. The right square bracket (]) and the backslash ()
must be quoted with a backslash if you want to use it within the string.
^ Matches the beginning of a line.
$ Matches the end of a line. (^*$ matches any entire line)
EXAMPLES FILES
None.
SEE ALSO grep(1), fgrep(1), egrep(1)DIAGNOSTICS NOTES
Even if a match occurs more than once per line, the line is output only once.
Quote special pattern matching characters to prevent them from being expanded by the Command Interpreter.
BUGS
The length of the pattern is currently limited to 100 characters.
This limit is reduced by 38 if the -w option is used.
