![对文本文件的每一行运行 Python 脚本](https://linux22.com/image/899157/%E5%AF%B9%E6%96%87%E6%9C%AC%E6%96%87%E4%BB%B6%E7%9A%84%E6%AF%8F%E4%B8%80%E8%A1%8C%E8%BF%90%E8%A1%8C%20Python%20%E8%84%9A%E6%9C%AC.png)
如何在 bash 中执行以下任务?
我需要编写一个脚本,对文本文件的每一行分别运行一个 python 脚本作为输入,然后将结果保存在以读取文件的行命名的 json 文件中。
因此文本文件 10tweets.txt 如下所示:
cat 10tweets.txt

@realDonaldTrump Thank you for saying you won't use vulger language anymore. Talk about Sanders & Clinton. Take Cruz as VP. Mexican votes!!!

我希望输出文件夹中的输出像 1.json、2.json、3.json、4.json、5.json。
不确定如何在 bash 脚本中使用exec entity_sentiment.py "$@"
并将其链接到文件中的每一行。脚本的运行方式如下
$ python entity_sentiment.py sentiment-entities-text "Thank you for saying you won't use vulger language anymore"
Mentions:
Name: "vulger language"
Begin Offset : 35
Content : vulger language
Magnitude : 0.699999988079071
Sentiment : -0.699999988079071
Type : 2
Salience: 1.0
Sentiment: magnitude: 0.699999988079071
score: -0.699999988079071
例如,脚本的输入可以假定为文件的第一行。
基本上,运行以下 bash 脚本只会分析文件的最后一行并将其保存在 1.json 中
#!/bin/bash
n=1
while read -u 3 -r line; do
python entity_sentiment.py sentiment-entities-text "$line" > "$((n++)).json"
done 3< 10tweets.txt
下面是我在 bash IRC 频道中运行建议时发生的片段:https://pastebin.com/raw/VQpPFJYs和https://pastebin.com/raw/GQefrTX0
答案1
您可以read
逐行输入文件,并使用类似以下命令将命令应用于每一行
#!/bin/bash
n=1
while read -r line; do
python entity_sentiment.py sentiment-entities-text "$line" > "$((n++)).json"
done < input.txt
我不明白这exec entity_sentiment.py "$@"
会有什么帮助。
答案2
感谢IRC bash社区
#!/bin/bash
n=1
while read -u 3 -r line; do
echo $n "${line::30}"
python entity_sentiment.py sentiment-entities-text "$line" > "$((n++)).json"
((n++))
done 3< 10tweets.txt
