Verbose command cp
Hi,

I have sometimes a problem when i want to copy files from a nas, it's the nas which have a problem when it is very requested by a lot of users, the command cp turn and don't stop (the file size does not increase) and it's lock.

Is it possible to verbose this command ?
I try with the flag -v but doesn't work

thank you.

I have found a solution:

Code:
{ cp fileOnNAS fileToLocal 2>&1 & };while [ 1 ];do taille=$(du fileToLocal | awk '{print $1}');echo $taille;sleep 5;taille1=$(du fileToLocal | awk '{print $1}');echo $taille1;if [ $taille1 == $taille ];then break and do something ;fi;done

You might try rsync, which might be better at retrying. A cleaner loop is to save size_last and loop, so there is just one du line. Also, you can use 'read size_var name_var' in place of awk call.
Code:
cp fileOnNAS fileToLocal
export taille1=-1
 
while [ 1 ]
do
 du fileToLocal
 sleep 5
done | while read taille b
do
 if [ "$taille1" = "$taille" ]
 then
  do something and break
 fi
 taille1=$taille
 echo $taille
done
