To be more clear, on any files return by the command find :
1° The start pattern to search § is generaly at line 11 but should be more or less
2° The start pattern to search § is always on a new line starting with the comment character # which is followed by one ore more space or tab
3°) The end pattern to search ɸ is always the second one on the same line. Some thing like
^#.*ɸ.*ɸ.*#.*$
4°)Between the first pattern § and the last pattern ɸ there is at least 3 line :

Code:

#    §2017_08_23§                      #
#    ¨version:11-0-2¨                  #
#    ɸmodif_version:2-2-1ɸ             #

But it could be more

Code:

#    §2019_01_13§                      #
#                                      #
#                                      #
#    ¨version:1-0-0¨                  #
#                                      #
#                                      #
#    ɸmodif_version:0-0-3ɸ             #

I am looking for something like ( the following syntax is surely bad ) :
Set start and stop address; replace every things between start and stop including start and stop by the multi-line block of text :

Code:

sed '/§.*§ /,/ɸ.*ɸ/{s/.*/§2019_08_24§                      #\
#                                      #\
#    ¨version:3-0-0¨                  #
#                                      #
#    ɸmodif_version:1-1-1ɸ/}' some_file.sh

Or if the substitution text is in a bash variables :

Code:

REPLACE_VAR="$(cat <<-EOF §2019_08_24§                      #\
#                                      #\
#    ¨version:3-0-0¨                  #
#                                      #
#    ɸmodif_version:1-1-1ɸ EOF )"

Then :

Code:

sed '/§.*§ /,/ɸ.*ɸ/{s/.*/'"$REPLACE_VAR"'/}' some_file.sh

Any help is welcome
