load average: 0.00, 0.00, 0.01
User

pts/1 12:21pm w
root
dtremote 10:46am 4:35

用who可以看出用户是从哪里登陆的
bash-2.03# who

用finger同时可以查看用户信息:
bash-2.03# finger

bash-2.03#
Ø
查找UID,GID
bash-2.03# id
uid=0(root) gid=1(other)
§2.2 创建和编辑文件(cat, touch, cp, mv, vi)
Ø
使用cat
bash-2.03# cat > meil
hello
bash-2.03# cat meil
hello
bash-2.03# cat >> meil
hello again
bash-2.03# cat meil
hello
hello again
bash-2.03#
Ø
使用touch
Touch 具有创建文件和修改文件修改时间的功能
bash-2.03# ls -l touch.txt
touch.txt: No such file or directory
bash-2.03# touch touch.txt
bash-2.03# ls -l touch.txt
-rw-r--r--
1 root other 0 Sep
7 15:38 touch.txt
bash-2.03# touch touch.txt
bash-2.03# ls -l touch.txt
-rw-r--r--
1 root other 0 Sep
7 15:40 touch.txt
bash-2.03#
Ø
使用cp ,mv
Ø
使用Text Editor
命令的启动方式有:
/usr/openwin/bin/textedit
&
/usr/dt/bin/dtpad&
Ø
使用vi
注意的是solaris中不支持使用退格.编辑时常用i,a,表示insert , append. D 表示delete, o表示open一个新行.y 表示拷贝,注意是小写. P表示put, 注意是大写.
以下是linux中相关,多数能通用.
需要加强掌握的vi命令
w 移动下个字的开头 word
b 跳到上自个的开头
:1,#d, 删除指定行
X
删除当前光标的左字符
#x
删除后面的#个字符
D
删除到行尾
cw
change word,修改一个单词,
c#w
修改#个单词
cc 修改行
C 替换到行尾
r
replace 取代一个字符
R 取代多个字符
yw 拷贝一个word
P 粘贴
yy 拷贝一行
#yy
拷贝#行
.
重复上一个命令
查找过程中忽略大小写:
:set ic 英文猜测是ignore case , 恢复默认配置:set noic:
读文件到当前位置: :r
file1 英文猜测是read
也可以插入指定行: :line# r filename
编辑多个文件, vi
file1 file2 file3, 键入:n进入下一个文件, 进入下一个文件,不保存对当前文件的修改,键入:n!
