Our customers send us an e-mail reuqesting information about some onvoices. We write the e-mail into a text file to filter the invoice numbers. But the invoice number are mixed with the text.
I am trying to create a script file to get just the invoice nomber from the text file and put it into another text file to read it from our aplicacion. But I do not know how to do it, becaus I do no have enough experience with Unix scripts shells.
The invoice numbers is always a 10 (ten) numeric character ans it cam be mixed with special characters.
I have been trying with this command but with not good results.
grep “[0-9]” file.txt
grep “[0-9]\” file.txt
grep “[0-9]\$” file.txt
grep “[0-9]\{10\}” file.etx
etc …
Body text from the e-mail
