Shell Programming and Scripting

its creating only 700bytes sometimes 300bytes each *.img files.
total copied is only 37MB in that folder.
has already created upto 4 *.img files.

Strange, perhaps EOF chars in the random input are truncating the output file
try conv=binary on the dd

Code:

i=1
DT=`date +%Y%m%d`
while [ $i -lt 100 ]
do
    dd if=/dev/random conv=binary of=5gb_${DT}_$i.img bs=128M count=40
    let i=i+1
done

dd: invalid conversion 'binary'

this is what i get error message..

Does it do the same sort of thing using /dev/zero?

yes same with /dev/zero
thnx

what if i just copy files from network to folder named /test called file instead of dd.

then create for loop inorder to run 100 loops creating filename as file1 file2...file100

displaying output with total files copied, $date. $size.

thanks

That should work, but I still find it weird that dd isn't doing what it does for me here.

Code:

#!/bin/bash
#create 2GB test file first.
dd if=/dev/zero of=/data1/test bs=128M count=200

#start to create test1 test2...test100
i=1
while [ $i -lt 100 ]
do
#copy
   cp -r /data1/test_$date_$i
   let i=i+1
done

.................
somewhere in the copy section i'm getting error.
actually, i'd like to create test1 test2 test3..test100 file of 2gb continue copying ...
can anyone pls. provide me suggestion in
#copy line.

thanks
