This article mainly introduces the shell recursive function how to circularly copy files to the designated directory, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Code:

#! / bin/shrecursive () {for file in $1 do subfile= `ls $2 $3 then rm $file` for subsubfile in $subfile do # echo $subsubfile if ["$subsubfile" = = "$2 $3/$file"] then rm-rf $3/$file mv $subsubfile $3/$file else recursive `ls $2 $3Compact $file` $2 $3/$file Fi done done} cd / tmpmkdir update;tar-zxvf update.tgz-C update;chmod-R 755 / tmp/update/*;rootdir= "/ tmp/update" filelist= `ls / tmp/update/ `for file in $filelistdo subfile= `ls $rootdir/$ file`for subsubfile in $subfile do if ["$subsubfile"! = "$rootdir/$file"] then $(recursive `ls $rootdir/$ file` $rootdir/$file) # rm-rf / $file/$subfile # mv $rootdir/$file/$subsubfile / $file break 1 Else kill-9 `ps | grep $file` rm-f / usr/bin/$file mv $rootdir/$file / usr/bin fi donedone#reboot

The following are new additions

Create soft links to all files in the folder, and linked files can be specified to be saved to other directories

When you assign a filelist, you can specify the source path

In the following sentence "ln-s $file arm-linux-" $lastwd ", you can specify the directory of the linked file, for example, the source path is the current path, and the destination path is also the current path.

# / bin/bash

Filelist= `ls. / `

For file in $filelist

Do

Firstwd=$file | cut-d "-"-F1

# if ["$firstwd" = = "arm"]

# then

Lastwd= `echo "$file" | sed's Unip. Sed-[] $/\ 1Unip'`

Echo $lastwd

Ln-s $file arm-linux- "$lastwd"

# fi

Done
