bash scripting using $@

Hello all,

Before linux allowed file names with spaces I could do something like this in bash :-

for i in `ls -1`
do
do-some-stuff-to $i
done

Now $i gets split up via the spaces in the file name. How do you get the same result (as the above simple script) for file names with spaces?

I understand that "$@" is used somehow but I can't get my old brain around it anymore. I'm using 4.2.37(1)-release (x86_64-redhat-linux-gnu) if it's relevant.

Hi,

please don't use ls for things like that. It is better to use shell globbing, and you should always quote your variables. Try the following:
Code:
for i in *
do
  dosomestuffto "$i"
done
HTH,

Evo2.

Thanks Evo2. Shell globbing - noted.

If I am not mistaken, Unix / Linux has always allowed spaces in file names. It just was not a good idea------and still isn't.

You're right. We just never used them before ...
