Answer is No on Root.sh lg_root.sh

usage: chmod [-R][-h] MODE FILE...

Change mode of listed file (recursively with -R).

-h : do not follow symbolic links.

MODE can be (comma-separated) stanzas: [ugoa][+-=][rwxstXugo]

Stanzas are applied in order: For each category (u = user,

g = group, o = other, a = all three, if none specified default is a),

set (+), clear (-), or copy (=), r = read, w = write, x = execute.

s = u+s = suid, g+s = sgid, o+s = sticky. (+t is an alias for o+s).

suid/sgid: execute as the user/group who owns the file.

sticky: can't delete files you don't own out of this directory

X = x for directories or if any category already has x set.

Or MODE can be an octal value up to 7777 ug uuugggooo top +

bit 1 = o+x, bit 1<<8 = u+w, 1<<11 = g+1 sstrwxrwxrwx bottom

Examples:

chmod u+w file - allow owner of "file" to write to it.

chmod 744 file - user can read/write/execute, everyone else read only
