Try to quote the date command like:

dat="$(date +"DOC%Y%m%d%H%M%S")"

...and remove the quote (typo) after ls DOC*.xml in my previous posts:

Code:
ls DOC*.xml |
awk -v dat="$(date +"DOC%Y%m%d%H%M%S")" ' {
of=sprintf("%02d.xml",++c)
print "mv " $0 " " dat of
}' | sh

Hi Pravin,

finally works fine.
But i need to change this :
if [ $i == 100 ] become if [ $i = 100 ]

thanks very much for your help and kindness Smilie

awk: syntax error near line 1
awk: bailing out near line 1

You may be using a shell the other posters are not expecting. Be sure there are no spaces between = and $( as in dat=$(

Do you know if you have bash, bourne, ksh, zsh....? which one?
