linux删除文件
怎样使用shell脚本修改文件:
/dev/sdb1 /opt/storea ext3 defaults 0 0
/dev/sdb2 /opt/storeb ext3 defaults 0 0
/dev/sdb1 /opt/storea ext3 defaults 0 0
/dev/sdb2 /opt/storeb ext3 defaults 0 0
修改成：
/dev/sdb1 /opt/storea ext3 defaults 0 0
/dev/sdb2 /opt/storeb ext3 defaults 0 0
/dev/sdb1 /opt/storea ext3 defaults 0 0
/dev/sdb2 /opt/storeb ext3 defaults 0 0
/dev/sdb1 /opt/storea ext3 defaults 0 0
/dev/sdb2 /opt/storeb ext3 defaults 0 0
修改成：
/dev/sdb1 /opt/storea ext3 defaults 0 0
/dev/sdb2 /opt/storeb ext3 defaults 0 0
