bash: iterating through txt file lines can't read last line

This code can read all lines in the file.txt except the last line any ideas why.

while read p; do
  echo $p
done < file.txt
Solution

  • If you're in doubt about the last \n in the file, you can try:

    while read p; do
    echo "$p"
done < <(grep '' file.txt)

    grep is not picky about the line endings ;)

    You can use grep . file.txt for skipping empty lines.
