uniq

Another command called uniq gives us another way of controlling the elimination of duplicate lines .

另一个名为uniq的命令为我们提供了另一种删除重复行的方式。

The uniq command can also ignore some fields .

uniq命令还可以忽略某些字段。

Remember what you learned about character and numeric sorting back in the Sort and uniq section .

回忆一下Sort和uniq小节中介绍的字符和数值排序。

Uniq reduces the list to the following

uniq可将列表精简为

Again , note how Perl was an intermediate tool between find , sort and uniq .

此外，请注意Perl是如何成为find、sort和uniq之间的中间工具的。

However , both sort and uniq require data entry or input from the standard input device ( stdin ) .

但是sort和uniq则需要从标准输入设备（stdin）请求数据输入。

Finally , sort and uniq in sequence ensure that repeated album names will be printed only once .

最后，按顺序的sort和uniq确保了重复的专辑名只打印一次。

Results : The modified CTAB method showed the highest yield , while the UniQ ion-exchange method showed the lowest yield of genomic DNA .

结果：三种方法制备基因组DNA纯度接近，但改进CTAB法产率最高，UniQ法产率最低。经典CTAB法和UniQ法提取基因组DNA易降解。

Both sort and uniq print outcomes to stdout .

sort和uniq都将输出打印到stdout。

If necessary , you can extend the pipeline shown above further and redirect the output of uniq to yet another utility .

如有需要，您可进一步扩展管道，将uniq的输出重定向到另外的实用工具。

To learn more about the extensive features of find , sort , and uniq , refer to each utility 's man page on your UNIX system .

要了解find、sort和uniq的更多扩展特性，请参阅您的UNIX系统中每种实用工具的man页。

Our sort was by collating sequence , so uniq gives us the " 10 apple " line instead of the " 1 apple " .

我们的排序是按照字符序列进行的，因此uniq显示的是“10apple”行，而不是“1apple”。

The uniq command normally operates on sorted files , and removes consecutive identical lines from any file , whether sorted or not .

uniq命令通常操作已排序的文件，并从文件（不管是否排序）中删除连续的相同行。

However , if the original list of Marx Brothers is sorted first ( reordering all occurrences of a name into a continuous run ), running uniq yields this result

但是，如果首先对MarxBrothers的初始列表进行排序（在连续运行中对多次出现的名称进行重排），运行uniq会生成以下结果

The Uniq () function is declared to take a range , so it will only be called once , even when invoked on a range of lines in the buffer .

Uniq（）函数被声明为接受一个范围，因此只能调用一次，即使在缓冲区内的一个行范围上调用时。

Then , use awk to strip out the command name minus options and arguments , and pass the sorted list to uniq to give an enumerated list .

然后，使用awk删除命令名称减号选项和参数，然后将经过排序的列表传递给uniq以得到一个枚举列表。

Therefore , the output of the entire script is piped through sort , and then uniq to yield an alphabetized list of unique commands found in your $ PATH .

因此，整个脚本的输出通过sort、然后通过uniq进行管道传输，以产生在您的$PATH中找到的唯一命令的字母排序列表。

Methods : Genomic DNA was extracted by classical CTAB method , modified CTAB method with the use of lysozyme and UniQ ion-exchange method , the quality and quantity of genomic DNA were compared .

方法：用经典CTAB提取法、改进CTAB法（溶菌酶处理结合CTAB提取法）、UniQ柱吸附提取法制备苛求芽孢杆菌基因组DNA，比较产物完整性和用于PCR扩增的有效性。
