bash脚本linux - 使用目录作为用户输入参数，并将所有子目录复制到/ tmp / folder，其名称与输入目录相同

Question

I want to create a script called package.sh which should:

• Use directory as input parameter (can be relative or absolute pathname)
• Recursively identify all sub directories of the input directory and recreate this structure in /tmp/. For example: for an input parameter /home/eddy a directory /tmp/eddy is created.
• All the text files and script files below the input directory should be copied to the corresponding directory in /tmp

I am new to bash script so I would like to get some help. Thanks so much

Answer 1

well why not just copy that directory /home/eddy to /tmp ? you can use some --exclude flags if you use rsync for copying in order to filter the files you need.

Answer 2

Something like this then:

#!/bin/bash
cp -r `realpath $1` /tmp

this copies the dir given as the first argument, to /tmp.

But as you say you only want *.txt and *.sh files copied so this should work instead

#!/bin/bash
cp `find $1 -name "*.txt" | xargs realpath` /tmp
cp `find $1 -name "*.sh" | xargs realpath` /tmp

But this doesn't recreate the directory structure like you want so you need cpio for that

#!/bin/bash
find $1 -regextype posix-awk -regex "(.*\.txt|.*\.sh)" | cpio -pdv /tmp

To include the criteria that the .sh files have to have the executable flag set (skip the copy if it is not set) then we have to use two lines:

#!/bin/bash
find $1 -name "*.txt" | cpio -pdv /tmp
find $1 -perm /u=x,g=x,o=x -name "*.sh" | cpio -pdv /tmp
