Transforming txt file before etiting in the wordprocessor (solved)

[zakend]

We have rather big text file. Any line is ended with the EOL.
We need to edit it in Libreoffice with sensible praragraphs.

The script has to:

1. input new line after [.\n] on the end of line,
2. input new line after [?\n] on the end of line,
3. input new line after [!\n] on the end of line,
3. change [,\n] for [space] on the end of line,
4. change [-\n] for [space] on the end of line if there is no [space] before [-]
5. change [\n] for [space] on the end of line if there is no next [\n] after [\n]

After help I have in this list the final script will be

#v+

#!/usr/bin/awk -f
#from https://groups.google.com/forum/?hl=pl&fromgroups=#!topic/comp.lang.awk/1SiyHFrILLU

FNR<=40 { print } # FNR lines without changed them
FNR>=41 { l = l != "" ? l" "$0 : $0 } # FNR lines wchich will change
/^.*[.?!]$/ { print l"\n"; l = "" } # transformation of text
END { print l } # printing output efect of changed lines

#v-
