Linux system cut, make an extremely streamlined linux-script to automate the copying of commands and dependent library files

the 2nd chapter uses the script to implement the automatic Copy command and the dependent library file

This article is mainly for my last blog http://blog.51cto.com/linuxprince/2045703 to improve, the previous article in the Copy command and the process of relying on the library file is completely manual, it appears particularly low, This chapter improves the process and is implemented in a scripted manner.

2.1 Command-specific implementation methods

Create a script file bincp.sh Enter the contents:

#!/bin/bash

#

Despath=/mnt/sysroot

LIBCP () {

libpath=${1%/*}

[!-D $LIBPATH] && mkdir-p $LIBPATH

[!-e $DESPATH $] && CP $ $DESPATH $libpath

}

BINCP () {

binpath=${1%/*}

[!-D $BINPATH] && mkdir-p $DESPATH $binpath

[!-e $DESPATH $] && CP $ $DESPATH $binpath

For LIB in ' LDD $ | Grep-o "/lib\ (64\) \{0,1\}/[^[:space:]]\{1,\}";

Do libcp $LIB;

Done

}

Bincp/bin/ls

take a look at what you did when you copied the/bin/ls command:

Note: At this point the streamlined a Linux system virtual machine cannot be a startup or a pending state and must be in a shutdown state.

Open the streamlined the Linux system can see the results immediately, such as:
