Shell 命令 - tr,sort,paste,nl

Shell command - tr,sort,paste,nl

我有这个作业

FILE 变量是恰好包含 30 行的文本文件的名称。每行仅包含一个单词,由大小写字母和数字组成。

更改此文件,使所有数字从单词中消失,所有字母更改为小写,并且修改后的单词按字母顺序升序排列。修改后的文件将采用三列单独表格的格式,其中第一列将包含排序后的前 10 个单词,第二列包含第二个 10 个单词,其余的包含第三个单词。给文件的行编号。

input:

hUeY65u
9sjKdfh
A56oi4
22cfe4HW
Gws6K
zh71p6t
...

output:
     1  aoi     gwsk    sjkdfh
     2  cfehw   hueyu   zhpt
     ...

我创建了这个脚本,它适用于我,但不适用于学校服务器。你不知道问题可能出在哪里。谢谢

cat $FILE | tr '[:upper:]' '[:lower:]' | tr -d "[0-9]" | sort >file1.txt;  
split -l 10 file1.txt; paste xaa xab xac >file2.txt; nl file2.txt; 



    Stderr mismatch:

GNU awk 的替代解决方案:

awk '{ gsub(/[[:digit:]]/,"",[=10=]); # Strip out the numbers
       map[tolower([=10=])]="" # Create an array with the line at the index in lower case
     } 
 END { PROCINFO["sorted_in"]="@ind_str_asc"; # Set the array sorting order
     for ( i in map ) { 
        printf "%s\t",i;cnt++; # Loop the array and print the entries. Also increment a count variable
        if (cnt==3 || cnt==6 || cnt==9) { printf "\n"  # When the count variable is 3,6 or 9 print a new line
        } 
        if (cnt==10) { printf "\n";exit # If the count is 10 exit
        } 
     } 
  }' file

一个班轮:

awk '{ gsub(/[[:digit:]]/,"",[=11=]);map[tolower([=11=])]="" } END { PROCINFO["sorted_in"]="@ind_str_asc";for ( i in map ) { printf "%s\t",i;cnt++;if (cnt==3 || cnt==6 || cnt==9) { printf "\n" } if (cnt==10) { printf "\n";exit } } }' file

您可以使用 pr 来排列列。不需要中间文件:

tr [:upper:] [:lower:] < "${FILE}" \
| tr -d [:digit:] \
| sort \
| pr -t3 \
| nl

或一行:

tr [:upper:] [:lower:] < "${FILE}" | tr -d [:digit:] | sort | pr -t3 | nl
