Bash expansion
Hello.
I cannot write a command without using eval.
Any help is welcome

Note 1 : What does the function SOMETHING has no importance.
Note 2 : What does the command find has no importance.

It is an expansion variable problem : where to put ["] or [\"] or [ '] or anythings else

What works (FILTRE_1 and FILTRE_2 are taken into account) :

Code:
function CHERCHE () {

    MY_PATH1="$1"
    if [[  ! -d "$MY_PATH1" ]] ; then
        echo "doing : $MY_PATH1"
        /usr/bin/kate "$MY_PATH1"
    fi
}
export -f CHERCHE

MY_PATH="/home/bidon"

FILTRE_1=" -path  $MY_PATH/.local/share/kscreen  -o -path  $MY_PATH/.local/share/baloo   -o -path  $MY_PATH/.dbus"

FILTRE_2=" ! -name \".direct*\"  ! -name \".Xauthority\"  ! -name \".xsession*\"  ! -name \".bash_history\" "

CMD="find \"$MY_PATH\"  -type d \( $FILTRE_1  \) -prune -o  \( $FILTRE_2 -exec bash -c 'CHERCHE \$0 '  {} \; \)  "
echo "COMMAND : $CMD"
eval "$CMD"

# The command return 9 files which is the good result

What does not works (FILTRE_1 is taken into account, FILTRE_2 or FILTRE_3 or FILTRE_2 is ignored ) :
Filter_2 is same as above

Code:
FILTRE_2=" ! -name \".direct*\"  ! -name \".Xauthority\"  ! -name \".xsession*\"  ! -name \".bash_history\" "

FILTRE_3=' ! -name ".direct*"  ! -name ".Xauthority"  ! -name ".xsession*"  ! -name ".bash_history" '

FILTRE_4=" ! -name '.direct*'  ! -name '.Xauthority' ! -name '.xsession*'  ! -name '.bash_history' "

find "$MY_PATH"  -type d \( $FILTRE_1  \) -prune -o  \( $FILTRE_2 -exec bash -c 'CHERCHE "$0" ' {} \;  \)
#FILTER_2 does nothing

find "$MY_PATH"  -type d \( $FILTRE_1  \) -prune -o  \( $FILTRE_3 -exec bash -c 'CHERCHE "$0" ' {} \;  \)
#FILTER_3 does nothing

find "$MY_PATH"  -type d \( $FILTRE_1  \) -prune -o  \( $FILTRE_4 -exec bash -c 'CHERCHE "$0" ' {} \;  \)
#FILTER_4 does nothing

#Each command return 15 files because filter 3,4,5 , does nothing.

LEARN ABOUT DEBIAN

dh_installdeb

DH_INSTALLDEB(1)						     Debhelper							  DH_INSTALLDEB(1)

NAME

       dh_installdeb - install files into the DEBIAN directory

SYNOPSIS

       dh_installdeb [debhelperoptions]

DESCRIPTION

       dh_installdeb is a debhelper program that is responsible for installing files into the DEBIAN directories in package build directories with
       the correct permissions.

FILES

       package.postinst
       package.preinst
       package.postrm
       package.prerm
	   These maintainer scripts are installed into the DEBIAN directory.

	   Inside the scripts, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands.

       package.triggers
       package.shlibs
	   These control files are installed into the DEBIAN directory.

       package.conffiles
	   This control file will be installed into the DEBIAN directory.

	   In v3 compatibility mode and higher, all files in the etc/ directory in a package will automatically be flagged as conffiles by this
	   program, so there is no need to list them manually here.

       package.maintscript
	   Lines in this file correspond to dpkg-maintscript-helper(1) commands and parameters.  Any shell metacharacters will be escaped, so
	   arbitrary shell code cannot be inserted here.  For example, a line such as "mv_conffile /etc/oldconffile /etc/newconffile" will insert
	   maintainer script snippets into all maintainer scripts sufficient to move that conffile.

	   A versioned Pre-Dependency on dpkg is needed to use dpkg-maintscript-helper(1). An appropriate Pre-Dependency is set in
	   ${misc:Pre-Depends} ; you should make sure to put that token into an appropriate place in your debian/control file.
