你可以翻看我之前的帖子
来这个版 大家都是放松的。不管bash 谁也好 没必要牵扯到个人。

发帖数: 273 | 4 想实现以下功能：
file1:
NP 4
要改成：
NP 5
在终端下：
$ sed '/^NP/s/[0-9]/5/' file1
可以完成。
现在要写一个bash scirpt 批量做这件事
#!/bin/bash
for((n=1;n<=3;n++))
do
sed '/^NP/s/[0-9]/${n}/' file1 > file1.$n
done
这样不成功， file1.1 是这样的
NP ${n}
怎样才能吧$n实际的值传给script中的sed呢？
我知道用perl可以做的，只是想用一下sed这个简单工具，先谢了 |

when i do ./ch.sh, it still stays in the same directory. only when i do

anyone knows the reason? how to make it run ./ch.sh? |

based on this, i made a script that you can go up any number of directories
easily. for example, up 3 will go up three directories from current dir.
#!/bin/bash
# go up any number of directories directly.
if [[ $# -eq 0 ]]
then
echo "going up one directory"
cd ..
elif [[ $# -eq 1 ]]
then
echo "going up $1 directory"
for (( i=1; i<=$1; i++ ))

发帖数: 12463 | 14 win10的linux subsystem太爽了
其实这个subsystem存在很多年了
但是一直都是鸡肋，远不如cygwin流行
我去年听传言说这个要在windows 10里面remove了
还觉得非常遗憾，因为即使鸡肋，也有翻身的可能
要是去掉了，就没戏了
不成想软软雄起了一把，win10内置官方支持的ubuntu bash shell
对我这种喜欢win+lin的人简直太方便了
刚刚装了python numpy一套玩意，跟ubuntu下面一样方便
几乎完美了
现在唯一的问题：bash.exe太简陋了，跟putty差不多，有没有第三方工具，那怕是个
wrapper也好
起码给我一个tab支持吧 |

发帖数: 6090 | 22 可以的，不过你说的太笼统了，你具体想实现什么？
可以上google上多查查，先确定你用的是bash还是c-shell什么的，不同的shell有不同
的flavor。
% finger user 可以输出你用的是bash还是c-shell
% cat a.txt b.txt 可以把a接到b的后面，类似R里的 c（a，b）
其他的一时还想不出来。
如果有些东西在Unix里不好实现，你可以写个R script，里面你从读文件，
manipulation，然后write.table都写好，存成一个.r的file (e.g. tmp.r，用下面的
命令可以直接在unix里调用R：
% R CMD BATCH tmp.r
就可以得到你在R里自己定义好的输出文件。
刚学unix，抛砖引玉 |
