Add functionality to small Linux and automatically add dependent libraries to the appropriate location

To add functionality to small Linux, let's write a script.

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

Important points of knowledge: FILE=/ETC/LOCAL/SRC

from left to right

Echo ${file#/} A # indicates that the first/left content is stripped out of the execution result to ETC/LOCAL/SRC

Echo ${file##/} represents a left-to-right look, finds the last/and removes all left-hand content from the execution result to/SRC (for filename)

From right to left

Echo ${file%/*} Search from right to left/find first will/and right content all delete execution result to/etc/local (directory for fetching files)

Echo ${file%%/*} Go from right to left to the last/and remove all of its contents to the right

Done

}

Read-p "Your command:" CMD

! Which $CMD && echo "wrong command" && read-p "Input again" CMD && continue

Command= ' which $CMD | Grep-v "^alias" | Grep-o "[^[:space:]]\{1,\}" '

BINCP $COMMAND

echo "Copy $COMMAND finished"

Read-p "Continue:" CMD

Done

At last

Mkdir/mnt/sysroot/lib/modules

Modinfo Mii The execution result has a path and then copies the path

cp/lib/modules/2.6.18....mii.ko/mnt/sysroot/lib/modules/

Modeinfo Pcnet32 the execution results have a path and then copy

Cp/lib/modules/2.6.18....net.pcnet32.ko

Sync

We look forward to automatically loading these two modules when booting

Vim/mnt/sysroot/etc/rc.d/rc.sysinit

Insmod/lib/modules/mii.ko

Insmod/lib/modules/pcnet32.ko

Ifconfig eth0 192.168.9.224/16
