為文字檔案的每一行運行 Python 腳本

為文字檔案的每一行運行 Python 腳本

如何在 bash 中執行以下任務？

我需要編寫一個腳本，在文字檔案的每一行上單獨執行 python 腳本作為輸入，然後將結果保存在以讀取檔案的行命名的 json 檔案中。

因此文字檔 10tweets.txt 如下所示：

貓 10tweets.txt

我希望輸出資料夾中的輸出類似於 1.json、2.json、3.json、4.json、5.json。

不知道如何在 bash 腳本中使用exec entity_sentiment.py "$@"並將其連結到文件中的每一行。腳本的運作方式如下

$ 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，可以假定腳本的輸入是檔案的第一行。

基本上，執行以下 bash 腳本僅分析檔案的最後一行並將其保存在 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

以下是我在 bash IRC 頻道中運行建議時發生的情況的片段：https://pastebin.com/raw/VQpPFJYs和https://pastebin.com/raw/GQefrTX0

答案1

您可以read逐行輸入檔案並使用類似的命令將命令應用於每一行

#!/bin/bash

n=1

while read -r line; do
  python entity_sentiment.py sentiment-entities-text "$line" > "$((n++)).json"
done < input.txt

我不知道exec entity_sentiment.py "$@"會有什麼幫助。

答案2

感謝 IRC bash 社區

#!/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
