    Something like this would do:

    xargs cat <filenames.txt

    The xargs program reads its standard input, and for each line of input runs the cat program with the input lines as argument(s).

    If you really want to do this in a loop, you can:

    for fn in `cat filenames.txt`; do
    echo "the next file is $fn"
    cat $fn
    done

    Is there a bug in a bash loop?
    Zathrus spotted a typical bug in the loop implementation, and also hinted that since i is a text variable, continuous conversions to-and-fro numbers are performed with an associated slow-down. This is an improved version of the Bash loop: echo $i let i++ If the only thing that we want is the echo, then we could write echo $((i++)).

    Should I for loop over the results of a shell command?
    Never for loop over the results of a shell command if you want to process it line by line unless you are changing the value of the internal field separator $IFS to \n. This is because the lines will get subject of word splitting which leads to the actual results you are seeing. Meaning if you for example have a file like this:

    How to use Bash for a list of words?
    Of course, this has the same problem as the for(()) solution, being tied to Bash and even a particular version (if this matters to you). The Bash for consists on a variable (the iterator) and a list of words where the iterator will, well, iterate. So, if you have a limited list of words, just put them in the following syntax: doSomething($w)

    What if end is high in Bash?
    However, there is the issue of memory usage if END is high. Note that seq $END would suffice, as the default is to start from 1. From man seq: "If FIRST or INCREMENT is omitted, it defaults to 1". The seq method is the simplest, but Bash has built-in arithmetic evaluation. echo $i
