Shell script recursive traversal directory and subdirectory example share _linux shell

The script that recursively iterates through the directory with the shell writes recursively traverses the specified directory and prints the file name under the directory.

Example 1:

Copy Code code as follows:

#!/bin/sh

function Scandir () {
Local Cur_dir Parent_dir Workdir
Workdir=$1
CD ${workdir}
if [${workdir} = "/"]
Then
Cur_dir= ""
Else
cur_dir=$ (PWD)
Fi

For dirlist in $ (LS ${cur_dir})
Todo
If test-d ${dirlist};then
CD ${dirlist}
Scandir ${cur_dir}/${dirlist}
Cd..
Else
Echo ${cur_dir}/${dirlist}
Fi
Done
}

If test-d $
Then
Scandir $
Elif Test-f $
Then
echo "You are input a file but not a directory,pls reinput and try Again"
Exit 1
Else
echo "The Directory isn ' t exist which you input,pls input a new one!!"
Exit 1
Fi

Instance 2: Recursive reading of directories and their subdirectories

Copy Code code as follows:

#! /bin/bash
function Read_dir () {
For file in ' ls $ '
Todo
If [-D $/$file]//Note there must be a space between here, or you will be able to error
Then
Read_dir "/" $file
Else
echo $ "/" $file
Fi
Done
}

#测试目录 Test
Read_dir Test

This gives test.sh the Execute permission to execute

Copy Code code as follows:

chmod +x test.sh
SH test.sh

This allows you to read the catalog file by passing parameters.

Example 3:

Copy Code code as follows:

Recursive implementation of each subdirectory of the subdirectories ...

#!/bin/bash

#modify. Func

doit ()//processing of non-directory files in the current directory, ignoring directory files

{

Oldname= ' ls | grep "$1$" '

For name in $oldname

Todo

If [-D "$name]"

Then:

Else

Basename= ' echo $name | Awk-f "." ' {print '} '

Newname= "$basename $"

Echo-e "$PWD/$name \t\t$newname"

MV $name $newname

count= ' expr ${count} + 1 '

Fi

Done

return 0

}

Do_recursive ()//starting from current directory, recursively processing each directory

{

Doit $ $

for filename in ' ls '

Todo

If [-D "$filename]"

Then

CD $filename

Do_recursive $ $

Cd..

Fi

Done

return 0

}

Modify ()//process The current directory and report the result, which is equivalent to the main function, and can be directly invoked do_recursive

{

params=2

If [$#-ne $PARAMS]

Then

echo "usage:mv_to. Suf1. Suf2"

Return 1

Fi

Count=0

Do_recursive $ $

echo "complete! $count files have been modified. "

return 0

}
