求能实现两个功能的shell脚本
发现用linux不懂shell就像打仗不会使枪一样。刚学。大家可以把自己认为常用的脚本粘出来。越初级的越好!我现在有二个需要解决
1 去了文件中的行号。大家在论坛发代码时有时会写上行号,如
1 2 echo "hello";
3 ?>
怎么把1,2,3给去了


2shell的配色方案
就是怎么修改.bashrc,让终端显示更加清晰

您只允许发表100分内的帖子。怎么还有这限制!!!不是我不想多加点分。CSDN不让。

------解决方案--------------------
试试这个(第一个)
sed 's/^[0-9]*\s//g' filename 



第二个不熟
------解决方案--------------------
你用什么编辑器? 文件行号一般是通过编辑器的属性设置取消和显示的。
------解决方案--------------------
回答第一个问题,test.txt为源文件,result.txt 经过处理后保存的文件名:

[[email protected] scripts]$ cat test.txt 
1 2 echo "hello";
3 ?>
[[email protected] scripts]$ cut -c3- test.txt > result.txt
[[email protected] scripts]$ cat result.txt 
echo "hello";
?>
[[email protected] scripts]$
------解决方案--------------------
