如何按字段查询得到文件相关的内容

molaifeng

大家好，我在/var/asg/log/confRec/ 路径下放了三个这样的文件conference20121012.rec conference20121018.rec conference20121019.rec，文件里的内容大致为如下样式

1. 
   
2. 
   
3. 1350551303:2001:2003 was set to unmute
   
4. 1350551304:2001:2002 was set to unmute
   
5. 1350551307:2001:2002 was kicked out from conference
   
6. 1350551308:2001:2002 was left conference
   
7. 1350551310:2001:2002 was invited to join the conference
   
8. 1350551311:2001:2002 was join in conference
   
9. 1350551349:2001:2002 was set to unmute
   
10. 1350551369:2001:2002 was set to mute
    
11. 1350551415:2001:conference end
    
12. 1350551416:2001:2002 was left conference
    
13. 1350551416:2001:2003 was left conference
    
14.

我写了个shell脚本

1. 
   
2. #!/bin/sh
   
3. 
   
4. path="/var/asg/log/confRec/";
   
5. 
   
6. function queryData()
   
7. {
   
8.     if [ ! -d $path ]
   
9.     then
   
10.         echo ""
    
11.         exit
    
12.     fi
    
13. 
    
14.     sdate=`echo $1 | cut -d: -f1`
    
15.     edate=`echo $1 | cut -d: -f2`
    
16.     num=`echo $1 | cut -d: -f3`
    
17.     file=`ls $path | grep [0-9]`
    
18.    
    
19.    
    
20.     for x in $file
    
21.     do
    
22.         tac $x | awk -v num=$num 'BEGIN{
    
23.         FS=":";
    
24.         }
    
25.         {
    
26.             if( (num!="" && $2==num) || num=="" ){
    
27.                 printf("%s\n",$0);
    
28.             }
    
29.         }'
    
30.     done
    
31. 
    
32. 
    
33. }
    
34. 
    
35. #
    
36. # main routine
    
37. #
    
38. 
    
39. action="$1"
    
40. setting="$2"
    
41. 
    
42. case $action in
    
43. 
    
44.     query_data)
    
45.         queryData $setting
    
46.     ;;
    
47. 
    
48.     *)
    
49.     ;;
    
50.

本来是想实现查询在开始时间到结束时间之内文件的内容的，可是第一步都显示不出来，也就是在文件内按字段查询，是不是哪里出现了问题
