leger ?

for i in `seq 0 32`;
if [ "$(sed '/^[ ]*#\|#\|^$\|^\n*$/d' $file | grep c${i} | wc -l)" -gt "0" ]
then
j=$(($i+1))
sed -i -e '/\<hoplahop\>/a \temp c'${i}' = variable['$j']' $file
fi
done

comme dans les precedents posts doit pouvoir etre remplacé par

for i in `seq 0 32`;
if [ "$(sed '/^[ |#|\n|\t]*$/d' $file | grep c${i} | wc -l)" -gt "0" ]
then
j=$(($i+1))
sed -i -e '/\<hoplahop\>/a \temp c'${i}' = variable['$j']' $file
