Re: [Help-bash] first part

[Eduardo Bustamante]

I'm sorry, but this is actually bad advice.

* There's no point in forking awk for every line, you can just run awk
on the whole file
* You are not quoting $field correctly (it's "$field", not $field)
* 'echo $var' might fail for cases where $var looks like a flag

Use:

while IFS=- read -r f rest; do
  printf '%s\n' "$f"
done < file

No forking, no quoting problem, no issues with funny input.
