In HPSpeak, “supported” and “works” are not synonymous. They have different meanings:

Supported, known to work -> warm fuzzies all around
Supported, not known to not work -> an HPite may be in trouble
Supported, known to not work -> an HPite is in trouble
Unsupported, known to work -> lucky today, unlucky tomorrow?
Unsupported, not known to not work -> there but for the grace of Turing
Unsupported, known to not work -> no, it was not deliberate ;-)

It is from an ITRC post of HP co-worker Rick Jones.

UNIX is still popular among its users for mission-critical systems, even though the OS has taken a hit in recent times.

An interesting read about mission-critical systems selection by Coleman Parks for HP – “UNIX still a hit for mission-critical systems”:

The majority of companies using UNIX will be sticking with it for their mission-critical systems,
even though use of the operating system has declined in recent times.

“According to the Coleman Parkes findings, the current operating system of choice for mission-critical systems is Solaris, created by Sun Microsystems, which was recently acquired by Oracle. HP-UX was in second place, followed by Windows.”

I doubt that HP-UX was second place. Oh well, this report is made for HP. You know.

Answer:

Method 1:

Use vi or vim,

After opening the file, type :set list, all the tabs will shown as “^I”

This file^Icontains some spaces  and^I^Itabs.
Do you^I see any ^I ^I tab?
