Linux使用技巧学习笔记

1.在执行perl  -MCPAN  -e shell 时,如果提示说Can't locate CPAN.pm in  @INC,说明CPAN.pm没有随着perl安装,这时需要到 www.cpan.com下载CPAN-1.9205.tar.gz进行安装,执行:

$ tar -xzf CPAN-1.9205.tar.gz

$ cd CPAN-1.9205

$ perl Makefile.PL

$ make

$ make test

$ sudo make install  2.使用cpan安装perl模块的命令:

$sudo perl -MCPAN -e shell

cpan>install POE::Component::IRC3.如果在笔记本上安装Fedora8时,在到

running /sbin/loader时停止不动了,这时需要在启动时用[TAB]键修改启动命令行,加上

acpi=off apm=off即可。

4. 当fedora8刚刚安装好后,系统每次启动都会自动运行yum-updatesd这一系统服务,这会造成用yum对系统或软件进行升级时出现如下类似错误:

# yum install "something"

Existing lock /var/run/yum.pid: another copy is running as pid 2587.

Another app is currently holding the yum lock; waiting for it to exit...

Another app is currently holding the yum lock; waiting for it to exit...解决办法:

# /sbin/chkconfig --level 5 yum-updatesd off

Configuring sudo

visudo ---> /usr/sbin/visudo

#sudo yum -y install yum-fastestmirror

Cannot access repository dir //var/cache/yum/livna

solution: sudo/su rootmplayerplug-in installation guide:http://mplayerplug-in.sourceforge.net/install.php

注意firefox的目录

6.英文(外文)语言环境下的中文输入

首先要确保系统中安装了中文字体,如文泉译宋体WenQuanYi Bitmap Song以及

scim scim-lang-chinese scim-pinyin scim-python-chinese scim-fcitx然后在用户"~"目录下的.bash_profile中添加以下内容:

export LC_CTYPE=zh_CN.GBK

export XMODIFIERS="@im=SCIM"

scim -d注销,重新登陆即可。

7. 让Nautilus具有资源管理器外观:

Preferences --> Behavior --> Behavior --> Always open in browser windows
