The UMASK value masks out the bits. The
permissions that each position in the UMASK masks out are the same as the file
permissions themselves. So, the left-most position masks out the owner
permission, the middle position the group, and the right most masks out all
others. If we have UMASK=007, the permissions
for owner and group are not
touched. However, for others, we have the value 7, which is obtained by setting
all bits. Because this is a mask,
all bits are unset. (The way I remember this
is that the bits are inverted. Where it is set in the UMASK, it will be unset in
the permissions,
and vice versa.)
meheksharma on 20 Feb 17We as an human are thinking round the clock.We face issues which impacts our daily life in positive or negative way. The clear vision and mission of one's life set the tone of your thought process. We are also aware that every humans goes through up's and down which lead us to a situation of growth or loss of confidence. We are habitual of developing perceptions and subsequently react to situation but miserably fails to look our inner thought process as humans tends to be partial. Thought process posses vitamins which may kick-start any activities in positive or negative manner. In our professional or personal life, we tend to develop perception about work to employees to family members that lead us to self induced thought process. Self Induced thought process can be of positive which I called as Constructive and Destructive.
