一、循环列出目录下所有文件

#!/bin/bash

function frfile()

{

local basefolder=$1

echo $basefolder

#local filename

for filename in $(ls $basefolder)

do

local fullpathfile=$basefolder/$filename

if [ -d $fullpathfile ]

then

echo ======dir======

ft=`ls $fullpathfile`

if [ ! -z "$ft" ]

then

echo ==$fullpathfile not empty==

frfile $fullpathfile

else

echo ==$fullpathfile empty==

fi

else

echo $fullpathfile

#cat -n $fullpathfile | grep found

fi

done

return

}

basefolder=`dirname $0`

echo "basefolder $basefolder"

frfile $basefolder/$1

对于目录结构如下

# tree emptydir

emptydir

|-- bf 非空目录

| `-- b.t

|-- def

`-- noted 非空目录

|-- abc

`-- ed 空目录

3 directories, 3 files

列出其文件为

# ./listfiles.sh emptydir

basefolder .

./emptydir

======dir======

==./emptydir/bf not empty==

./emptydir/bf

./emptydir/bf/b.t

./emptydir/def

======dir======

==./emptydir/noted not empty==

./emptydir/noted

./emptydir/noted/abc

======dir======

==./emptydir/noted/ed empty==

二、查找目录下包含指定字符串的文件

#!/bin/bash

searchstring=$2

function frfile()

{

local basefolder=$1

#echo $basefolder

for filename in $(ls $basefolder)

do

local fullpathfile=$basefolder/$filename

if [ -d $fullpathfile ]

then

#echo ======dir======

ft=`ls $fullpathfile`

if [ ! -z "$ft" ]

then

#echo ==$fullpathfile not empty==

frfile $fullpathfile

#else

#echo ==$fullpathfile empty==

fi

else

#echo $fullpathfile

cat -n $fullpathfile | grep "$searchstring"

if [ $? = 0 ]

then

echo $fullpathfile

fi

fi

done

return

}

basefolder=`dirname $0`

#echo "basefolder $basefolder"

if [ ! -d $basefolder/$1 ]

then

cat -n $basefolder/$1 | grep "$searchstring"

else

frfile $basefolder/$1

fi

查找emptydir 目录下 包含字符串“found" 或 ”not found" 的文件并给出字符串在文件中的位置

# ./searchstr.sh emptydir "found"

1 not found

2 found

./emptydir/bf/b.t

# ./searchstr.sh emptydir "not found"

1 not found

./emptydir/bf/b.t

注：b.t文件中共两行即

not found

found
