Create a function that prints it's arguments to the log file, then evals the
arguments redirecting the results to the log file. Call that function for each
command you want to execute. Something like this:

$ function doit() { printf " %s\n" "$1"; eval "$1"; } >"$FICHIER_LG"
$ doit 'echo "hello"'
$ cat "$FICHIER_LG"
echo "hello"
hello

Since from your example you want everything to go to a logfile, you can
start off the script with

exec $FICHIER_LG 2>&1

and remove all the ">$FICHIER_LG" and ">$FICHIER_LG 2>&1" from the
individual lines.

You could then consider writing a function like

x(){
printf -- " %s\n" "$*"
eval "$@"
}

if you have control over all the inputs. Use it like

x 'mkdir -p $DUMPREST/$BASEDEST'

Here an example of a procedure, you see it's very verbose and it's difficult
to read and maintain.


Thanks for any advices
