我如何遍历关键字的出现频率 [英] how can i loop through the coming frequency of the keyword

问题描述

----我的文本文件，我必须从中搜索关键字[文件名---测试]< cat -Evt文件>

---- my text file from which i have to search for the keywords [name of the file --- test] <cat -Evt file>

    centos is my bro$
    red hat is my course$
    ubuntu is my OS$
    fqdn is stupid $
    $
    $
    $
    tom outsmart jerry$
    red hat is my boy$
    jerry is samall 

------关键字文件为[word.txt]< cat -Evt文件>

------ keyword file is [word.txt] <cat -Evt file >

  red hat$
  we$
  hello$
  bye$
  Compensation

-----我的代码

  while read "p"; do
  paste  -d',' <(echo -n  "$p" ) <(echo "searchall") <(  grep -i "$p" test | wc -l) <(grep  -i -A 1  -B 1   "$p" test )
  done <word.txt
   

----我的期望是，输出应该是

---- my expectation ,output should be

 keyword,serchall,frequency,line above it
                            line it find keyword in
                            line below  it
              
 red hat,searchall,2,centos is my bro
                     red hat is my course
                     ubuntu is my OS                                
            
 red hat,searchall,2,tom outsmart jerry
                     red hat is my boy
                     jerry is samall

----但是从我的代码中输出了

---- but coming OUTPUT from my code

  red hat,searchall,2,centos is my bro
  ,,,red hat is my course
  ,,,ubuntu is my OS
  ,,,--
  ,,,tom outsmart jerry

  ,,,jerry is samall

----请给我建议，并指出正确的方向，以获得所需的输出.

---- please give me suggestion and point me in the right direction to get the desired output.

重写为更精确的格式-

while read key                          # read each search key 
do cnt=$(grep "$key" test|wc -l)        # count the hits
   pad="$key,searchall,$cnt,"           # build the "header" fields
   while read line                      # read the input from grep
   do if [[ "$line" =~ ^-- ]]           # treat hits separately
      then pad="$key,searchall,$cnt,"   # reset the "header"
           echo                         # add the blank line
           continue                     # skip to next line of data
      fi
      echo "$pad$line"                  # echo "header" and data
      pad="${pad//?/ }"                 # convert header to spacving
   done < <( grep -B1 -A1 "$key" test ) # pull hits for this key
   echo                                 # add blank lines between
done < word.txt                         # set stdin for the outer read                       

$: cat word.txt
course
red hat

$: ./tst
course,searchall,1,centos is my bro
                   red hat is my course
