ksh:shell脚本，用于以固定间隔在目录中存在的所有文件中搜索字符串 [英] ksh: shell script to search for a string in all files present in a directory at a regular interval

问题描述

我在UNIX(SUN)中有一个目录(输出).创建了两种类型的文件，文件名带有时间戳前缀.这些文件的创建间隔为10分钟. e. g:

I have a directory (output) in unix (SUN). There are two types of files created with timestamp prefix to the file name. These file are created on a regular interval of 10 minutes. e. g:

1.  20140129_170343_fail.csv (some lines are there)
2.  20140129_170343_success.csv (some lines are there)

现在，我必须在输出目录中存在的所有文件中搜索特定的字符串，如果在失败和成功文件中找到了该字符串，我必须计算这些文件中存在的行数并将输出保存到cnt_succ和cnt_fail变量.如果找不到该字符串，则在20秒的睡眠定时器后，我将在同一目录中再次搜索.

Now I have to search for a particular string in all the files present in the output directory and if the string is found in fail and success files, I have to count the number of lines present in those files and save the output to the cnt_succ and cnt_fail variables. If the string is not found I will search again in the same directory after a sleep timer of 20 seconds.

这是我的代码

#!/usr/bin/ksh

for i in 1 2
do
  grep -l 0140127_123933_part_hg_log_status.csv /osp/local/var/log/tool2/final_logs/* >log_t.txt;  ###  log_t.txt will contain all the matching file list
  while read line   ### reading the log_t.txt
  do
    echo "$line has following count"
    CNT=`wc -l $line|tr -s " "|cut -d" " -f2`
    CNT=`expr $CNT - 1`
    echo $CNT
  done <log_t.txt
  if [ $CNT > 0 ]
  then
    exit
  fi

  echo "waiitng"
  sleep 20
done

我面临的问题是，我无法在行中获取_success和_fail并检查它们的计数

The problem I'm facing is, I'm not able to get the _success and _fail in file in line and and check their count

推荐答案

最后，我能够找到解决方案.这是完整的代码:

Finaly I'm able to find the solution. Here is the complete code:

#!/usr/bin/ksh


file_name="0140127_123933.csv"

for i in 1 2
do

grep -l $file_name /osp/local/var/log/tool2/final_logs/* >log_t.txt;

    while read line
    do
    if [ $(echo "$line" |awk '/success/') ]           ## will check the success file
    then
    CNT_SUCC=`wc -l $line|tr -s " "|cut -d" " -f2`
    CNT_SUCC=`expr $CNT_SUCC - 1`

    fi

    if [ $(echo "$line" |awk '/fail/') ]             ## will check the fail file
    then
    CNT_FAIL=`wc -l $line|tr -s " "|cut -d" " -f2`
    CNT_FAIL=`expr $CNT_FAIL - 1`

    fi
    done <log_t.txt
    if [ $CNT_SUCC > 0 ] && [ $CNT_FAIL > 0 ]
    then
            echo " Fail count = $CNT_FAIL"
            echo " Success count =  $CNT_SUCC"
            exit
    fi

   echo "waitng for next search..."
   sleep 10
   done
