#Note that the "/dev/stderr" entries in some lines have wrapped.

#I then call setFieldsByWidth() in my main awk code as follows:
BEGIN {
  #FIELDWIDTHS="7 6 5 4 3 2 1" # for example
  # adjust the FIELDWIDTHS values as you see fit.
  FIELDWIDTHS="9 21 51 11 51 11 51 11 51 11 9 9" # for example
  OFS="|"
}
!/^[  ]*$/ {
  saveDollarZero = $0 # if you want it later
  setFieldsByWidth()
  # now we can manipulate $0, NF and $1 .. $NF as we wish
  # print $0 OFS
  print $1,$2,$3,$4,$5,$6,$7,$9,$10,$11,$12
  next

Code:

awk '{

        substr($1,10,20) "|" \
        substr($1,30,50) "|" \
        substr($1,80,10) "|" \
        substr($1,90,50) "|" \

Utiliser $ 0 au lieu de $ 1 (qui est ce que je devrais avoir utilisé):

Code:

awk '{
 print  substr($0,1,9) "|" \
        substr($0,10,20) "|" \
        substr($0,30,50) "|" \
        substr($0,80,10) "|" \
        substr($0,90,50) "|" \
        substr($0,140,10) "|" \
        substr($0,150,50) "|" \
        substr($0,200,10) "|" \
        substr($0,210,50) "|" \
        substr($0,260,10) "|" \
        substr($0,270,8) "|" \
        substr($0,278,8)
}' filename.txt > FinalResult.txt
