shell脚本--在n个文件中检索字符串然后算总数

    让我帮着写一个脚本，从一个目录下面所有的子目录（以日期为名）下面所有的日志文件中，搜索字符串'ANI is'，然后算出来多少行。

[xiaoqi@localhost Call]$ ls -d 2007-07-3*
2007-07-30 2007-07-31
[xiaoqi@localhost Call]$ ls 2007-07-3*
2007-07-30:
VAGFlowExecutor_2007-07-30_07.log VAGFlowExecutor_2007-07-30_15.log
VAGFlowExecutor_2007-07-30_08.log VAGFlowExecutor_2007-07-30_16.log
VAGFlowExecutor_2007-07-30_09.log VAGFlowExecutor_2007-07-30_17.log
VAGFlowExecutor_2007-07-30_10.log VAGFlowExecutor_2007-07-30_18.log
VAGFlowExecutor_2007-07-30_11.log VAGFlowExecutor_2007-07-30_19.log
VAGFlowExecutor_2007-07-30_12.log VAGFlowExecutor_2007-07-30_20.log
VAGFlowExecutor_2007-07-30_13.log VAGFlowExecutor_2007-07-30_21.log
VAGFlowExecutor_2007-07-30_14.log VAGFlowExecutor_2007-07-30_22.log

2007-07-31:
VAGFlowExecutor_2007-07-31_07.log VAGFlowExecutor_2007-07-31_14.log
VAGFlowExecutor_2007-07-31_08.log VAGFlowExecutor_2007-07-31_15.log
VAGFlowExecutor_2007-07-31_09.log VAGFlowExecutor_2007-07-31_16.log
VAGFlowExecutor_2007-07-31_10.log VAGFlowExecutor_2007-07-31_17.log
VAGFlowExecutor_2007-07-31_11.log VAGFlowExecutor_2007-07-31_19.log
VAGFlowExecutor_2007-07-31_12.log VAGFlowExecutor_2007-07-31_20.log
VAGFlowExecutor_2007-07-31_13.log


    因为子目录和里面的文件都有一定规则，所以写起来比较简单。用两个for就搞定了。

[xiaoqi@localhost Call]$ cat list.sh
#!/bin/bash
for i in ./20*
do
        for j in $i/*
        do
        echo "$j"" "`grep -Ra 'ANI is' $j|wc -l`
        done
done

for i in ./20*
do
echo "---------------------------------"
echo $i" "`grep -Ra 'ANI is' $i|wc -l`
echo "---------------------------------"
done

echo " "
echo "---------------------------------"
echo "just a moment ; the total is ...."
echo "the total is "`grep -Ra 'ANI is' *|wc -l`
echo "---------------------------------"


    执行效果如下：

[xiaoqi@localhost Call]$ ./list.sh

./2007-07-30
./2007-07-30/VAGFlowExecutor_2007-07-30_07.log 3
./2007-07-30/VAGFlowExecutor_2007-07-30_08.log 5
./2007-07-30/VAGFlowExecutor_2007-07-30_09.log 31
./2007-07-30/VAGFlowExecutor_2007-07-30_10.log 24
./2007-07-31
./2007-07-31/VAGFlowExecutor_2007-07-31_07.log 0
./2007-07-31/VAGFlowExecutor_2007-07-31_08.log 6
./2007-07-31/VAGFlowExecutor_2007-07-31_09.log 7
./2007-07-31/VAGFlowExecutor_2007-07-31_10.log 15
---------------------------------
./2007-07-30         199
---------------------------------
---------------------------------
./2007-07-31         111
---------------------------------

---------------------------------
just a moment ; the total is ....
the total is 23418
