Controlled For Loop

Shell Programming and Scripting
1

I have a for loop and i pass in number of times i want to loop as argument to script.

I have attached a snippet of my script. Problem is this does not work, if I manually replace the $NO_OF_LOOPS with a number in the script it works fine.

NO_OF_LOOPS=$1
for i in {0..$NO_OF_LOOPS}

Any help, i just want to control the no of loops via the argument i pass in.

How about this!

NO_OF_LOOPS=$1
for i in `seq 0 $NO_OF_LOOPS`
do
        echo $i
done
3 
 
NO_OF_LOOPS=$1
for i in `seq  0 $NO_OF_LOOPS`

This will not work.
Error:
seq: invalid floating point argument: _OF_LOOPS
Try `seq --help' for more information.

You need to precede $ infront of NO_OF_LOOPS

It should be like

for i in `seq  1 $NO_OF_LOOPS`

Now I corrected

Or in bash

for ((  i = 1 ;  i <= $1;  i++  ))
do
	echo "amit $i"
done

I get seq: command not found

kelseyh -

what shell are your using. seq is a bash shell feature.

Have you tried amitranjansahu's solution?
seq will be available under GNU.
