Although it should work.... why not use POSIX style which bas accept too. i=$((i+1)) For speed of shell script, it is faster to use dash and better to be portable. > Btw, an easier way to do a for loop of this sort in bash is to do "for > i in `seq 20`" (notice the backticks). Yep. I agree. Also with xargs command instead of shell loop, you should get faster script. > If you want to do a lot of text manipulation, it may feel more natural > to use Perl (or at least it feels more natural to me).
