I have to write a script that takes a sentence and prints the word count, character count (excluding the spaces), length of each word and the length. I know that there exist wc -m to counter number of characters in the word, but how to make use of it in script? #!/bin/bash mystring="one two three test five" maxlen=0; for token in $mystring; do echo -n "$token: "; echo -n $token | wc -m; if [ ${#token} -gt $maxlen ]; then maxlen=${#token}; fi; done echo "--------------------------"; echo -n "Total words: "; echo "$mystring" | wc -w; echo -n "Total chars: "; echo "$mystring" | wc -m; echo -n

wc - print newline, word, and byte counts for each file wc命令用于计算字数。 利用wc指令我们可以计算文件的Byte数、字数、或是列数，若不指定文件名称、或是所给予的文件名为"-"，则wc指令会从标准输入设备读取数据。 语法 ： wc [OPTION]... [FILE]... wc [OPTION]... --files0-from=F 参数： -c或--bytes或--chars 只显示Bytes数。 -l或--lines 只显示行数。 -w或--words 只显示字数。 -m，--chars 显示字符数 -L，--max-line-length 最长的行的长度 示例： 在默认情况下，wc将计算指定文件的行数、字数，以及字节数。 [root@oldboy oldboy]# cat name.txt user01 user02 user03 user04 user05 [root@oldboy oldboy]# wc name.txt 5 5 35 name.txt # 5行，词数5个，字节数35 来源： https://www.cnblogs.com/zoe233/p/11807568.html

The first child runs 'ls' command and outputs to pipe1. The second reads from pipe1 runs 'wc' and outputs to stdout. I'm just trying to add a third process in the middle that reads from pipe1 and outputs to pipe2. Basically what I'm trying to do ls | cat | wc -l What I'm trying to do: (ls)stdout -> pipe1 -> stdin(cat)stdout-> stdin(wc -l) -> stdout Nothing ever prints to stdout and the program never exits.

Is it possible to do something similar for reads? Somehow hint the CPU to read an entire cache line or a larger buffer instead of reading one word at a time? 回答1: Intel has a white-paper on copying from video RAM to main memory ; this should be similar but a lot simpler (because the data fits in 2 or 4 vector registers). It says that NT loads will pull a whole cache-line of
