for in shell

[oiram]

Hello:

A very easy question, how can I make a for loop with a range of numbers. I mean:

for i in [0-10000]
do
...........
done
Thanks.

hi,

rather use while or until :

I=0
while [ $i -lt 10000 ]
do
...
I=$(($I + 1))
done

Regards.

let x=0
while [ $x -lt 10000 ]
do

let x=$x+1
done

Hi,

This answer is for ksh.
I don't know by heart how to use for without using a function, but you can do it with a while loop:


#! /usr/bin/ksh
let i=1
while [[i -le 1000 ]]
do
let i=${i}+1
echo ${i}
done

Cheers,

Fran??ois-Xavier

Using shell integer variables, the syntax is...

let I=0
while (( I <= 10000 ));
do
...
let I=I+1
done

Hi

i=0
while($i -le 10000)
do
...
i=($i + 1)
done

[KapilRaj]

if also can be used

A=0
if [ $A -gt 100000 ]
then
exit 0
else
.....
.....
.....
A=`echo " $A + 1 " |bc`
fi

If you're running a (t)csh, you can use repeat

% repeat 10000 echo help

In the (k)sh you can fake this with a function

a5:/u/usr/merijn 102 > ksh
$ repeat () {
> let i=$1
> shift
> while [ $i -gt 0 ]; do
> $@
> let i=`expr $i - 1`
> done
> }
$ repeat 3 echo help
help
help
help
$
Exit 1

i=0
while [ $i != 10000 ]
do
let i=i+1

done

Just to increase the noise,
here another Bash feature:

$ echo $0
-bash
$ for ((i=0; i<10; i++));do printf "%3u Bash lets you do C-like loops\n" $i;don
e
