"Much like a vernacular, the universe of UNIX tools
changes almost perpetually. New tools crop up frequently, while
others are eternally modernized and adapted to suit emerging best
practices. Certain tools are used commonly; others are used more
infrequently. Some tools are perennial; occasionally, some are
obsoleted outright. To speak UNIX fluently, you have to keep up
with the "lingo."
"Watch many files with multitail
Whether you're a developer debugging new code or a systems
administrator monitoring a system, you often have to keep an eye on
many things at once. If you're a developer, you might watch a debug
log and stdout to track down a bug; if you're an administrator, you
might want to police activity to intercede as necessary. Usually,
both tasks require oodles of windows tiled on screen to keep a
watchful eye--perhaps tail in one window, less in another window,
and a command prompt in yet another."
