  • by redirecting the file:

        echo $line
    done < /path/to/file
    
  • by using awk:
    awk '{print $0}' /path/to/file
    
  • by using head an tail:
    f=/path/to/file
    total=$(wc -l $f)
    n=0
    while [ $n -lt $total ]
    do
        let n++
        line=$(head -n $n $f | tail -1)
        echo ${line}
