[plug] function error

[Jon Miller]

No I want to be able to read in a file (which has over a 100 names in it, each on a separate line) do a series of commands against each name. So I thought if I can get the command to read in a line do the commands and when finished read I the next and perform the same commands until it reaches the end of the file.

There is no auto-incrementing loop in bourne shell (or bash) scripting
that I'm aware of.

What is it you're trying to do?  Read the first 10 lines?  Use a
separate counter to control the loop:

  for counter in `seq 10` ; do
    read LINE || break
    # process $LINE
  done < username2.txt
