Sed 坚持做部分匹配

好的，考虑这个示例文件：

#!/usr/bin/env bash
cat > example_file.txt <<EOL
group, , price
1, S_BRN_, 3.21
1, S_WBS_BRN_, 4.11

2, F_WBS_BRN_, 2.11
2, F_BRN_, 2.11
2, F_BRN_WBS_, 2.11
EOL

我想要所有包含字符串“F_BRN_”或“S_BRN_”的行。我执行以下 sed：

sed -n '/S_BRN_\|F_BRN_/p' example_file.txt

我得到：

1, S_BRN_, 3.21
1, S_WBS_BRN_, 4.11
2, S_BRN_WBS, 9.2
2, F_WBS_BRN_, 2.11
2, F_BRN_, 2.11
2, F_BRN_WBS_, 2.11

我的问题是：如何防止部分匹配？例如 F_WBS_BRN_ 不包含子字符串 F_BRN_，因此不应返回它。

CLI 方法来压缩当前在压缩文件夹中的单个文件

5

我有一个压缩文件Data.zip（如果未压缩）包含许多文件：

file_1.txt    
file_2.txt
...    
...

我想要一个 CLI 命令将其转换为一个新文件夹Data_zipped ，其中包含Data.zip未压缩的单个文件：

Data_zipped/file_1.zip     
Data_zipped/file_2.zip
...
...

但诀窍在于它Data.zip 包含如此多的文件（而且它们总体上是如此之大），以至于我无法先解压缩 Data.zip，然后一口气压缩其中的各个文件：这一切都必须“即时”发生：

对于所有文件Data.zip/

获取第 i 个文件
把它压缩成name_of_that_file.zip
将压缩文件存储在新文件夹中Data_zipped

如何使用 CLI 做到这一点？

我修改了@George 的超清晰脚本，以帮助更好地解释文件夹结构：

#!/bin/bash

#Name of zip file
filename=$1

# Check if valid zip file is passed
if [[ $(file "$filename" | grep -o "Zip archive data") =~ "Zip archive data" ]]
then    

        # List the contents of the zip file
        unzip -l "$filename" 

        # Get the number of files in zip file
        count=$(unzip -l "$filename" | awk '{count = $2 - 2} END {print count}')

        echo "$count"
    
fi

exit 0

当我运行它时，我得到（我使用一个只有几个文件的令牌 Data.zip，但你明白了）：

./GU_script.sh Data.zip
Archive:  Data.zip
  Length      Date    Time    Name

---------                     -------
884063494                     7 files

所以基本上，我希望将Level1_file.csv其他文件单独压缩（-> Level1_file.zip）并放在一个文件夹中。

我最终结合了@George 和@David Foerster 的答案：

#!/bin/bash

#Name of zip file

# Check if valid zip file is passed
if file "$filename" | grep -wq "Zip archive data";
then    

        #!/bin/bash

在 ubuntu 16.04 上安装没有 Anaconda 的 Spyder3

5

（我已尝试按照此处的说明进行操作。我无法使用 Anaconda）

sudo apt-get install spyder3

安装 150MB 的好东西。然后，我这样做：

pip install -U spyder

然后我做

spyder3

我得到：

安装最新的 Rsymphony Ubuntu

可以Rsymphony通过以下方式安装：

apt-get install r-cran-rsymphony

但那是一个旧版本。当尝试安装最新的（从内部R）时，一个得到：

* installing *source* package ‘Rsymphony’ ...
** package ‘Rsymphony’ successfully unpacked and MD5 sums checked
Cannot find SYMPHONY libraries and headers.
See <https://projects.coin-or.org/SYMPHONY>.
ERROR: configuration failed for package ‘Rsymphony’

如何安装最新的 Rsymphony 软件包？

意外删除有线连接

Sed 坚持做部分匹配

wc -l *.py 用于所有子目录

用一个替换两个连续的 CR

使用文件名为文件夹中的所有 pdf 添加水印

AWK：将行数追加到模式的下一个出现（在一个巨大的文件中）

awk：仅打印特定警戒线模式之后的行

awk 用下一行同一列中的值替换第 i 列中的值

从前面的 csv 文件中移动特定列（按名称选择列）

awk：无法打开“文件名”进行输出（打开的文件太多）

在 Visual Studio Code python 中为文件设置 virtualenv

防止在恢复后调整窗口大小

awk：将第二行中的值，列（如果存在）设置为变量

awk：管道输出（有条件的）打印到 gzip

对于名称为字符串的文件夹中的所有文件，将单元格 (2,9) 中的值添加到文件名的末尾
