ifconfig -a

解压.tar文件

tar -xvf xx.tar

Redhat/Suse

Solaris

若Solaris报错则选择其他的解压方式

gtar压缩超长文件名，用tar解压时会报错“tar: ././@LongLink: typeflag 'L' not recognized, converting to regular file”，并在当前目录下生成一个LongLink文件

 

 

 

ln -s /usr/sfw/bin/gtar /usr/bin/gtar

gtar -xf xxx.tar

Solaris 10

先创建链接

后再解压

 

解压tar.gz

tar -zxvf xxx.tar.gz

Redhat/Suse

 

 

 

gzip -d xxx.tar.gz

tar -xvf xxx.tar

Solaris

 

 

 

gunzip -c xxx.tar.gz | tar -xvf -
