[Bash] Copy Large Number of Files on Linux

If you want to copy large number of files, it's not a good idea to use cp -r command directly because it will take a lot of time. It's better to use tar command to archive the files into a single file and then extract the file to the destination directory you want. The following is the Bash script to demonstrate how to copy large number of files efficiently:

1
2
3
4
5
6
7
8

#!/bin/bash

# $1 is the directory in which files to be copied
# $2 is the destination directory

tar cvf /tmp/foo.tar $1
tar xvf /tmp/foo.tar -C $2
rm /tmp/foo.tar

Tested on: Ubuntu Linux 16.04, bash 4.3.46(1).
