Code:
Source File
*************
# file: /local/test_1
# owner: own
# group: grp
user::rwx
group::r-x
other::r-x


# file: /local/test_1/2019
# owner: own
# group: grp
user::rwx
group::r-x
other::r-x

# file: /local/test_1/2019/10
# owner: own_01
# group: grp_02
user::rwx
group::r-x
other::r-x

# file: /local/test_1/2019/10.dum.txt
# owner: own_01
# group: grp_02
user::rwx
group::r-x
other::r-x

Target File :

# owner: own
# group: grp
user::rwx
group::r-x
other::r-x
default:user::rwx
default:group::r-x 
default:other::r-x
default:group:sgg:rwx
default:group:sgg_1:r-x


# file: /local/test_1/2019
# owner: own
# group: grp
user::rwx
group::r-x
other::r-x
default:user::rwx
default:group::r-x 
default:group:sgg_1:r-x


# file: /local/test_1/2019/10
# owner: own_01
# group: grp_02
user::rwx
group::r-x
other::r-x
default:user::rwx
default:group::r-x 
default:other::r-x
default:group:sgg_0:rwx
default:group:sgg_3:r-x

# file: /local/test_1/2019/10.dum.txt
# owner: own_01
# group: grp_02
user::rwx
group::r-x
other::r-x

Required Output:

man diff:


Quote:
NAME
GNU diff - compare files line by line

SYNOPSIS
diff [OPTION]... FILES

DESCRIPTION
Compare FILES line by line.

If your OS / shell don't offer "process substitution", try also:
Code:
sed 's/^# file.*/&\n\n&\n/' file2 | diff -y -b --suppress-common-lines - file1
