hi Guys,

when i run the below script its showing error "integer expression expected"

then
  scp server1:/root/file.2012-$1-0$i .
else
  scp server1:/root/file.2012-$1-$i .
fi

done

You cannot put a variable in a {n..m} construct. Try:

#!/bin/bash

for ((i=1; i<=$2; i++))
do
  scp "server1:/root/file.2012-$1-$(printf "%02d\n" "$i")"
done

Although this could be made more robust. Anything wrong with the input and your script will break. You could check the content of $1 and $2 before you enter the loop if you want to avoid that..

Hi Scrutinizer,

i am getting below error when i run the script.

i am using Red hat Linux.

this is the explanation of my script:

server1 containing below files
file.2012-05-01
file.2012-05-02
.
.
file.2012-05-09
file.2012-05-10
file.2012-05-11
.
.
.
now i plan to download passing the parameters such $1 and $2, $1 is month and $2 is date.
sometimes i want to download up to 1st 7days sometimes 1st 15days.
this is the requirement. if u didn't understand let me know.

thanks for reply
