centos_setting_local Centos用户的环境配置

centos的一些配置和常用环境稍稍不同，需要注意。

color shell

可以先设置一下colorshell。这个是绿色的

echo "PS1='\[\033[02;32m\]\u@\H:\[\033[02;36m\]\w\$\[\033[00m\] '" >> ~/.bashrc

如果需要设置一下前面为红色,参考arch的设置 history也设置一下

PS1='\[\e[0;31m\]\u\[\e[m\] \[\e[1;36m\]\w\[\e[m\] \[\e[1;32m\]\$\[\e[m\] \[\e[1;37m\]'
LS_COLORS=$LS_COLORS:'di=1;36:ln=36'

~/.bashrc

PS1='\[\e[0;31m\]\u@\h\[\e[m\] \[\e[1;36m\]\w\[\e[m\] \[\e[1;32m\]\$\[\e[m\] \[\e[1;37m\]'

let &colorcolumn="80,".join(range(400,999),",")     
highlight Comment ctermfg=green

如果需要设置用户后面有主机名，很简单修改一下\u@\h history也设置一下

PS1='\[\e[0;31m\]\u\[\e[m\] \[\e[1;34m\]\w\[\e[m\] \[\e[1;32m\]\$\[\e[m\] \[\e[1;37m\]'
PS1='\[\e[0;31m\]\u@\h\[\e[m\] \[\e[1;34m\]\w\[\e[m\] \[\e[1;32m\]\$\[\e[m\] \[\e[1;37m\]'
LS_COLORS=$LS_COLORS:'di=1;36:ln=36'

刚刚开始的时候，觉得curl的 -I 和一般不同，但man能找到相应设置，这个需要另外测试一下。

$ curl --version
curl 7.15.5 (x86_64-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5
Protocols: tftp ftp telnet dict ldap http file https ftps 
Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz

幸好grep和sed感觉差不多，awk不会用自动忽略。

$ grep --version
grep (GNU grep) 2.5.1

perl 感觉好像没问题，但注意pm是不能用了。自己的pm也懒得导。

$ perl -V

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
