Linux / Unix — pipe the output to join -


I am very new to Linux / Unix stuff, and from time to time I am doing some type of exercise. By the time I did not come in one part, I was practicing myself.

Plain sort quotes. 5 To join the output to join the pipe use field separator, read from stdin and quotes.comms, extract the output. T6

The problem is, I do not know what this part is saying.

A few days ago I have run this command on the server: 

  wget 'http://finance.yahoo.com/d/quotes.csv? S = BARC L + 0992.HK + RHT + AAPL + ADI + AEIS + AGNC + AMAT + AMGN + AMRN + ARCC + ARIA + ARNA + ATVI + BBRY + BIDU + BRCD + BRCM + BSFT + CENX + Serie + CMCSA + Coco + CSCO + CSIQ + CSOD + CTRP + CTSH + CYTX + DRYS + DTV + DXM + EA + EBAY + EGLE + ENDP + ESRX + EXPD + extr + Fang + Fast + Fb + FCEL + FITB + FLEX + Foxa + FSLR + FTR + Gale + GERN + Gilding Gold + GMCR + GRPN + GTAT + HBAN + HDS + HIMX + HSOL + IMGN + INTC + JASO + JBLU + JDSU + KERX + Line + Linta + MDLZ + MNKD + MPEL + MSFT + MU + MXIM + MYL + NFLX + NIHD + Nuan + NVDA + onnn + original + OTEX + OXBT + PENN + PMCS + psec + QCOM + RBCN + REGN + RFMD + RSOL + S CTY + Sina + Serie + SNDK + SPWR + SYMC + TSLA + Mars + TWGP + TXN + VOLC + WEN + YHOO + ZNGA and F = nab '-o quotes.csv

but produced The file quotes.csv was not sufficient enough to gain insights into finance and stuff so I need some help from you!

eckpointing When you complete this lesson, you will need to get it: 

  $ sha256sum -c quotationsahas quotes.T1: OK quote @ 2: OK citations.3: OK quotes. TE 4: OK quotes .5: OK quotation. T6: OK

  • quotes.csv Our source with a stock price The file is lines that have been terminated with CRLF, which is not unix predicted. This eliminates the LF that means remove the CR (\ r) byte from each line to use it sed (man-sed) option command, output for quotes // More information on

  • To check the checkpoint to run if quotes.t1 is OK.

  • Use head and tail commands to output the file to everyone except the first and last lines of quotation marks.

  • By separating the field from the pipe (vertical bar |) instead of comma 

      sed -re's /, ([0-9.] +), ([0-9.] +) / | \ 1 | \ 2 / g 'quote. T2 & gt; Quotes.t3

  • Sort numeric by third field (key), output to new separator, do not forget output to quotes. TQ Output The last five lines, cut out the first and third fields in the result quotes.t5

  • Plain sort quotes .5 and join the output pipe To join the use field separator, read from stdin and quotes.comms, output for quotes. T6

If necessary, I can post all parts of this exercise, but I am thinking that you will know that I But what to do Mainly I need to know what it means to be involved. I have searched Google on this, but I still do not get it.

Transfer a short version of the comments in one answer.

The original version of the question was asking:

A plain type of quotation .t5 and pipe to be included in the output. To join the usage area separator, to read from stdin and quotes.comms, extract the output. 6

You need to know that this is a command if you type - Specify one of your two input filenames, then it can be read with standard input.

Then, I think, quite straight forward: 

  sort quotes.5. Included- t '|' - QuotesMM & gt; Quotes.t6

Or maybe: 

  sort quotes.5. Included- t '|' Quotes.comm - & gt; Quotes.t6

I'm sure how you can tell what's needed, apart from standard input as 'studin and read from quotes.comms' Second and quotes.comms is the second meaning.
