I have a file containing more than 14000 records.
What I want to do is to process this file line by line and replace a String by anodher string returned by grep command.
For example:
Line :

```
/xxxxx/xxxxx/Class.java:67: Logger.w(TAG, "message");

```

My grep command to get **Class.java** string is (Class.java is juste an example):

```
grep -o '[a-zA-Z]*"*\.java"*'

```

I must, for each line, replace the **TAG** string by the **class.java** string return by grep command
