/var 包含系统一般运行时要改变的数据。通常这些数据所在的目录的大小是要经常变化或扩充的。原来 /var 目录中有些内容是在 /usr 中的,但为了保持 /usr 目录的相对稳定,就把那些需要经常改变的目录放到 /var 中了。每个系统是特定的,即不通过网络与其他计算机共享。下面列出一些重要的目录 ( 一些不太重要的目录省略了 ) 。
1. /var/catman : 包括了格式化过的帮助 (man) 页。帮助页的源文件一般存在 /usr/man/catman 中;有些 man 页可能有预格式化的版本,存在 /usr/man/cat 中。而其他的 man 页在第一次看时都需要格式化,格式化完的版本存在 /var/man 中,这样其他人再看相同的页时就无须等待格式化了。 (/var/catman 经常被清除,就像清除临时目录一样。 )
2. /var/lib : 存放系统正常运行时要改变的文件。
3. /var/local : 存放 /usr/local 中安装的程序的可变数据 ( 即系统管理员安装的程序 ) 。注意,如果必要,
即使本地安装的程序也会使用其他 /var 目录,例如 /var/lock 。
4. /var/lock : 锁定文件。许多程序遵循在 /var/lock 中产生一个锁定文件的约定,以用来支持他们正在使用某个特定的设备或文件。其他程序注意到这个锁定文件时,就不会再使用这个设备或文件。
5. /var/log : 各种程序的日志 (log) 文件,尤其是 login (/var/log/wtmplog 纪录所有到系统的登录和注销 ) 和 syslog (/var/log/messages 纪录存储所有核心和系统程序信息 ) 。 /var/log 里的文件经常不确定地增长,应该定期清除。
6. /var/run : 保存在下一次系统引导前有效的关于系统的信息文件。例如, /var/run/utmp 包含当前登录的用户的信息。
7. /var/spool : 放置 “ 假脱机 (spool)” 程序的目录,如 mail 、 news 、打印队列和其他队列工作的目录。每个不同的 spool 在 /var/spool 下有自己的子目录,例如,用户的邮箱就存放在 /var/spool/mail 中。
8. /var/tmp : 比 /tmp 允许更大的或需要存在较长时间的临时文件。注意系统管理员可能不允许 /var/tmp 有很旧的文件。
/etc 文件系统
/etc 目录包含各种系统配置文件,下面说明其中的一些。其他的你应该知道它们属于哪个程序,并阅读该程序的 man 页。许多网络配置文件也在 /etc 中。
1. /etc/rc 或 /etc/rc.d 或 /etc/rc?.d : 启动、或改变运行级时运行的脚本或脚本的目录。
2. /etc/passwd : 用户数据库,其中的域给出了用户名、真实姓名、用户起始目录、加密口令和用户的其他信息。
3. /etc/fdprm : 软盘参数表,用以说明不同的软盘格式。可用 setfdprm 进行设置。更多的信息见 setfdprm 的帮助页。
4. /etc/fstab : 指定启动时需要自动安装的文件系统列表。也包括用 swapon -a 启用的 swap 区的信息。
5. /etc/group : 类似 /etc/passwd ,但说明的不是用户信息而是组的信息。包括组的各种数据。
6. /etc/inittab : init 的配置文件。
7. /etc/issue : 包括用户在登录提示符前的输出信息。通常包括系统的一段短说明或欢迎信息。具体内容由系统管理员确定。
8. /etc/magic : “file” 的配置文件。包含不同文件格式的说明, “file” 基于它猜测文件类型。
9. /etc/motd : motd 是 message of the day 的缩写,用户成功登录后自动输出。内容由系统管理员确定。常用于通告信息,如计划关机时间的警告等。
10. /etc/mtab : 当前安装的文件系统列表。由脚本 (scritp) 初始化,并由 mount 命令自动更新。当需要一个当前安装的文件系统的列表时使用 ( 例如 df 命令 ) 。
11. /etc/shadow : 在安装了影子 (shadow) 口令软件的系统上的影子口令文件。影子口令文件将 /etc/passwd 文件中的加密口令移动到 /etc/shadow 中,而后者只对超级用户 (root) 可读。这使破译口令更困难,以此增加系统的安全性。
12. /etc/login.defs : login 命令的配置文件。
13. /etc/printcap : 类似 /etc/termcap ,但针对打印机。语法不同。
14. /etc/profile 、 /etc/csh.login 、 /etc/csh.cshrc : 登录或启动时 bourne 或 cshells 执行的文件。这允许系统管理员为所有用户建立全局缺省环境。
15. /etc/securetty : 确认安全终端,即哪个终端允许超级用户 (root) 登录。一般只列出虚拟控制台,这样就不可能 ( 至少很困难 ) 通过调制解调器 (modem) 或网络闯入系统并得到超级用户特权。
16. /etc/shells : 列出可以使用的 shell 。 chsh 命令允许用户在本文件指定范围内改变登录的 shell 。提供一
台机器 ftp 服务的服务进程 ftpd 检查用户 shell 是否列在 /etc/shells 文件中,如果不是,将不允许该用户登录。
17. /etc/termcap : 终端性能数据库。说明不同的终端用什么 “ 转义序列 ” 控制。写程序时不直接输出转义
序列 ( 这样只能工作于特定品牌的终端 ) ,而是从 /etc/termcap 中查找要做的工作的正确序列。这样,多数的程序可以在多数终端上运行。
命令缩写:
ls:list(列出目录内容)
cd:Change Directory(改变目录)
su:switch user 切换用户
rpm:redhat package manager 红帽子打包管理器
pwd:print work directory 打印当前目录 显示出当前工作目录的绝对路径
ps: process status(进程状态,类似于windows的任务管理器) 常用参数:-auxf
ps -auxf 显示进程状态
df: disk free 其功能是显示磁盘可用空间数目信息及空间结点信息。换句话说,就是报告在任何安装的设备或目录中,还剩多少自由的空间。
rpm: 即RedHat Package Management,是RedHat的发明之一
rmdir:Remove Directory(删除目录)
rm:Remove(删除目录或文件)
cat: concatenate连锁 cat file1 file2>>file3把文件1和文件2的内容联合起来放到file3中
insmod: install module,载入模块
ln -s : link -soft 创建一个软链接,相当于创建一个快捷方式
mkdir:Make Directory(创建目录
touch
man: Manual
pwd:Print working directory
su:Swith user
cd:Change directory
ls:List files
ps:Process Status
mkdir:Make directory
rmdir:Remove directory
mkfs: Make file system
fsck:File system check
cat: Concatenate
uname: Unix name
df: Disk free
du: Disk usage
lsmod: List modules
mv: Move file
rm: Remove file
cp: Copy file
ln: Link files
fg: Foreground
bg: Background
chown: Change owner
chgrp: Change group
chmod: Change mode
umount: Unmount
dd: 本来应根据其功能描述“Convert an copy”命名为“cc”,但“cc”已经被用以代表“C Complier”,所以命名为“dd”
tar:Tape archive
ldd:List dynamic dependencies
insmod:Install module
rmmod:Remove module
lsmod:List module
文件结尾的"rc"(如.bashrc、.xinitrc等):Resource configuration
Knnxxx / Snnxxx(位于rcx.d目录下):K(Kill);S(Service);nn(执行顺序号);xxx(服务标识)
.a(扩展名a):Archive,static library
.so(扩展名so):Shared object,dynamically linked library
.o(扩展名o):Object file,complied result of C/C++ source file
RPM:Red hat package manager
dpkg:Debian package manager
apt:Advanced package tool(Debian或基于Debian的发行版中提供)
