(rephrasing the question for better clarity.)
Suppose I have 1000 text files. Each file is a textual form, with fixed field descriptions and headers, but the data is different. For example, file 1:
The Foo Factory Date: 2015-10-02 Order Details ------------------------- Order ID: [ 1 ] Amount: [ 1 ] Order Price: [ 12.34 ] Have a nice day.
and file 2:
The Foo Factory Date: 2016-01-11 Order Details ------------------------- Order ID: [ 7 ] Amount: [ 17 ] Order Price: [ 543.21 ] Have a nice day.
etc. Now, suppose I went ahead and translated the field descriptions into French; and I deleted the values. So now I have:
L'usine Foo Date: Détails de commande ------------------------- Nm.du Commande: [ ] Montant: [ ] Prix du Commande: [ ] Bonne journée.
I don't really speak French so ignore any mistakes here. Anyway, the positions of all fields are exactly the same, but the non-field-value text is different. I want to apply this replacement to all of the files. How do I achieve that?
