shell script to iterate through text files and delete a string

  • 772

I have a few hundred text files in one directory with lists of users:

&usera
&userb
userc
&userd

note that some do not lead with the &. Also, in some files, the last line does not end with a newline character.

What is the simplest way in a shell script to go through all those files and remove, say userb, ensuring that each existing user remains on its own line?

thanks!
