perl中的这种写法是什么意思？
perl中的这种写法是什么意思？
最近看一个脚本文件，有如下的写法：my $usage =&&TXT;
ltib [-m &mode&] [options....]
& & Where:
& && &&&--mode|m
& && && & Where mode is either:
& && && && &prep& &
..........
TXT复制代码两端的TXT是不是perl中的一种什么写法？
刚开始接触这个，在一本书中也没找到这个语法。

楼上，不懂就谦虚一点嘛，或者Google一下嘛。因为你的问题实在太粗浅了，真的。
wxlfh 发表于
& & 能google到了也就不来问了。从来没接触过，有点粗浅的问题也没什么奇怪吗。
& &只是某些人的反应感觉实在可笑，让别人看到了那脆弱的自尊心。

当然也可以不回答，但不必那么多废话，论坛和文档都是学习的途径，论坛里不讨论问题，那要论坛干什么？
你上街问个路，对方说：“你他妈的手机没有GPS吗？不会自己查吗？没GPS总有GPRS吧，上去google一下啊？要不你装个google map啊？啥，不会？你他妈的是不是低智商啊？”，你会很爽吗？

昵称: t3gonline &时间:Hugging the book and closing his eyes “I Love My Perlita T she was the first boat I sent to America”. Thus exclaimed Carlo Riva at Riva Days when we presented him with
about PERLITA TOO&#8230;
A few days later
Mr. Riva invited us to his office, where we discussed the early days when he began to run how he tested and rejected suppliers until he was satisfied, and where he then signed our book.
He had read the book thoroughly
and was happy to spend an hour questioning us and elaborating on the details in our book, and telling us about the early days and his deep involvement in the design and building of the boats.
Our unique gauges were a prototype from the Swiss instrument & watch maker Jaeger.
PERLITA TOO is the only Riva ever equipped with these gauges. Likely they were too expensive, and Mr. Riva could use ‘off the shelf’ SW gauges from the US for considerably less cost.
A week later, we received .
Not long after we returned from Italy we headed back to Lake Washington with PERLITA for another sea trail and some photos. In Italy we had spent two weeks cruising in several later model Rivas, including
the very Last Tritone built by Riva. We have now had the unique experience of driving both the First, and the Last Tritones!
Our expedition to Lake Washington was exactly on the day of the 5 year anniversary of Perlitas departure to
to begin the long and expensive restoration journey which is now (sigh of relief) complete. And completed at a level of perfection beyond our dreams, and validated by the Ingenere himself!
WHEN YOU EMBRACE PERFECTION
In our opinion the Scripps V12 motor in PERLITA creates a boating experience totally different from other Rivas. I say this based on our own recent experiences, in Italy and in Washington.
PERLITA TOO is the only Riva remaining with the Scripps V12 of the 4 originally constructed in 1952 & 53.
So, how to describe it? First is the sound. The huge displacement (894 cu.in.), coupled with the long stroke, creates a deep smooth rumble completely different than a modern OHV V8. Next, the power at low RPM’s is smooth and effortless, bringing the boat on plane so quickly you’re surprised!
Interestingly, I can have a ‘normal’ conversation with companions in the front seat easily over the sound of the motor.
The hull of PERLITA TOO sports a lower deckline overall (which was modified in later boats for wider user appeal); and along with the very low 2-piece windshield, seems more ‘aerodynamic’, giving more of a ‘sports car’ feel (if you are inclined to make an automotive comparison). Certainly, some of this ride quality stems from meticulous reconstruction.
CASUDI says it feels “more like a speedboat”
than any other Riva Perlita Too has a much racier and sportier ride!
GOD IS IN THE DETAILS
Our visit lin August 2012 to Riva Days in Italy confirmed that you can build a great online community (as we have done with our
website and blog), but the power of those relationships created online is greatly magnified by meeting the members of our community “in real life”.
A special thanks to our fabulous Norwegian, German, Dutch and Italian communities and of course those from the US whom we met &#8220;in real life&#8221; for the very first time, all who made our time at Riva Days so valuable.
You have met PERLITA online, now please come and meet her “In Real Life”. When she is not out &#8220;speeding&#8221; across the water she can be found at , whose team of experts completed all the mechanical systems as though she were a Pebble Beach show car. PERLITA always enjoys showing off to the members of her community or ‘fan club’; after all, she started life as a !

Installing Perl modules from the Linux command line using the cpan command works fine, such as:
$ cpan [Module]
and after finishing I can see the module’s documentation via:
$ perldoc [Module]
But doing this via cfengine, which would just automate script the cpan command (in a shellcommands: list), the module gets installed, but perldoc will not work for it:
$ perldoc Text::Histogram
No documentation found for "Text::Histogram".*
However, invoking:
$ man Text::Histogram
will work just fine.
Setting a general environment variable for this (such as suggested by the perldoc man page) doesn't seem feasible as I observe the .pm files being placed in very diverse places.
Any hints about this?

perldoc searches the Perl module include path (@INC).
If perldoc can't find it, perl can't find it.
Try perl -wle 'use The::Module' to see if perl can load it.
If it can find it, then something weird is going on.
What likely happened, if you installed a module via a third party program (even if it's just using the cpan client), is it got installed to a different location and/or a with a different perl than the one you're using on the command line.
There's a number of reasons for this, the three most likely are...
It has a different PATH than you and found a different copy of cpan for a different perl.
It's configured the cpan client differently to install to a different PATH.
cpan is configured to install under the home directory, and it's running as a different user.
There is also the odd chance that the module has no documentation.
You can see what perldoc is doing to find the module with perldoc -D The::Module (this may be -v in older versions).
