linux详细教程(linux图解教程)

linux操作系统是基于什么操作诞生的?

inux操作系统诞生于1991 年10 月5 日,这是第一次对外公布的时间,创始人林纳斯·托瓦兹。

Linux的基本思想有两点:

第一,一切都是文件;

第二,每个软件都有确定的用途。

其中第一条详细来讲就是系统中的所有都归结为一个文件,包括命令、硬件和软件设备、操作系统、进程等等对于操作系统内核而言,都被视为拥有各自特性或类型的文件。至于说Linux是基于Unix的,很大程度上也是因为这两者的基本思想十分相近。

Linux是一款开源的操作系统,用户可以通过网络或其他途径免费获得,并可以任意修改其源代码。这是其他的操作系统所做不到的。正是由于这一点,来自全世界的无数程序员参与了Linux的修改、编写工作,程序员可以根据自己的兴趣和灵感对其进行改变,这让Linux吸收了无数程序员的精华,不断壮大。

linux sz命令详解?

sz命令会将选定的文件发送到本地机器

要使用sz命令首先要安装他

执行yum install lrzsz安装

然后执行命令sz filename就可以将文件从服务端发送到客户端

详细的命令参数如下

Usage: sz file …

   or: sz -{c|i} COMMAND

Send file(s) with ZMODEM/YMODEM/XMODEM protocol

    (X) = option applies to XMODEM only

    (Y) = option applies to YMODEM only

    (Z) = option applies to ZMODEM only

  -+, –append append to existing destination file (Z)

  -2, –twostop use 2 stop bits

  -4, –try-4k go up to 4K blocksize

      –start-4k start with 4K blocksize (doesn't try 8)

  -8, –try-8k go up to 8K blocksize

      –start-8k start with 8K blocksize

  -a, –ascii ASCII transfer (change CR/LF to LF)

  -b, –binary binary transfer

  -B, –bufsize N buffer N bytes (N==auto: buffer whole file)

  -c, –command COMMAND execute remote command COMMAND (Z)

  -C, –command-tries N try N times to execute a command (Z)

  -d, –dot-to-slash change '.' to '/' in pathnames (Y/Z)

      –delay-startup N sleep N seconds before doing anything

  -e, –escape escape all control characters (Z)

  -E, –rename force receiver to rename files it already has

  -f, –full-path send full pathname (Y/Z)

  -i, –immediate-command CMD send remote CMD, return immediately (Z)

  -h, –help print this usage message

  -k, –1k send 1024 byte packets (X)

  -L, –packetlen N limit subpacket length to N bytes (Z)

  -l, –framelen N limit frame length to N bytes (l>=L) (Z)

  -m, –min-bps N stop transmission if BPS below N

  -M, –min-bps-time N for at least N seconds (default: 120)

  -n, –newer send file if source newer (Z)

  -N, –newer-or-longer send file if source newer or longer (Z)

  -o, –16-bit-crc use 16 bit CRC instead of 32 bit CRC (Z)

  -O, –disable-timeouts disable timeout code, wait forever

  -p, –protect protect existing destination file (Z)

  -r, –resume resume interrupted file transfer (Z)

  -R, –restricted restricted, more secure mode

  -q, –quiet quiet (no progress reports)

  -s, –stop-at {HH:MM|+N} stop transmission at HH:MM or in N seconds

      –tcp build a TCP connection to transmit files

      –tcp-server open socket, wait for connection

  -u, –unlink unlink file after transmission

  -U, –unrestrict turn off restricted mode (if allowed to)

  -v, –verbose be verbose, provide debugging information

  -w, –windowsize N Window is N bytes (Z)

  -X, –xmodem use XMODEM protocol

  -y, –overwrite overwrite existing files

  -Y, –overwrite-or-skip overwrite existing files, else skip

      –ymodem use YMODEM protocol

  -Z, –zmodem use ZMODEM protocol

U盘安装Linux详细步骤?

以制作Ubuntu linux系统为例:

1、首先要下载Ubuntu系统,在搜索Ubuntu,打开Ubuntu官网。

2、然后在下载那里,选择桌面版。
