数据可以来自标准输入(stdin)、一个或多个文件,或其它命令的输出。它支持用户自定义函数和动态正则表达式等先进功能,是linux/unix下的一个强大编程工具。它在命令行中使用,但更多是作为脚本来使用。awk有很多内建的功能,比如数组、函数等,这是它和C语言的相同之处,灵活性是awk最大的优势。 全栈若城 2024/03/02...

This has the first read read input from stdin, and, because conceptually fish knows it's read in a pipe (technically: it uses its stdoutput() outputter_t), it writes the prompt to its own stdout, ignoring the pipe. (it then engages read's mode without a variable, which is to just...
(int [=4]) --stdin input from STDIN. If the STDIN is interleaved paired-end FASTQ, please also add --interleaved_in. --stdout output passing-filters reads to STDOUT. This option will result in interleaved FASTQ output for paired-end input. Disabled by default. --interleaved_in indicate ...
The scanf() function reads data from the standard input stream stdin into the locations given by each entry in the argument list. The argument list, if it exists, follows the format string. scanf() cannot be used if stdin has been reopened as a type=record or type=blocked file. The ssc...

If there are fewer words read from the input stream than there are names, the remaining names are assigned empty values. 在IFS变量中的字符用来把输入行分割成字或者段;参见第 3.4.8 节 “字分割”。反斜杠字符可以用来去除读入的下一个字符的特殊含义为了行的延续。
