“There are plenty such tools which are definitely very
useful for Linux admins. Here I am just trying to figure out 5 of
such useful tools which are used by a normal Linux administrator in
day to day operations. A tool which I think is most useful may not
fit in your usage and its definitely possible that you know some
awesome tool which I forgot to include here, for such case, I am
requesting hereby to please mention the tool in comments. One more
thing, I am mentioning here tools which are somewhat optional and
not absolutely required for everybody and excluding tool which have
no viable alternative and every Linux admin have to use them.. such
as SSH, SCP etc.”
