Question Need to echo a text where a (.) is added to the end of line during on-going copy or ftp
Hello All,

I would like to create a script to echo a text where a (.) dot is added every 2 seconds to the end of this text (with a limit of 10 dots) as long as a file copy or ftp is ongoing and once the copy is finished it adds "done" to the end of this text line. please see the below example:

Code:
#collect the BSSIM traces from OMC-R
echo "`tput setaf 4`Collecting the BSSIM traces..." #need to add a dot #every 2 sec (limit of 10 dots max.)and once copy is complete add the word "done" to the end of the line
echo "`tput setaf 4`Please enter the BSS Id: \c"
read BSSId
cd /alcatel/var/maintenance/trace
cp bssim_$BSSId.trace /alcatel/var/share/AFTR/MISC/MX_DATA/BSSIM
cd /alcatel/var/maintenance/hist
cp bssim_$BSSId.trace.old.$shortdate.* /alcatel/var/share/AFTR/MISC/MX_DATA/BSSIM
tput sgr0



 Thanks in advance

Code:
dots() ## USAGE: dots  [number_of_dots  [time_between_dots]]  ## Defaults: 10 and 2
{
  dotnum=${1:-10}
  sleepytime=${2:-2}
  while [ $(( dotnum -= 1 )) -ge 0 ]
  do
    printf "."
    sleep "$sleepytime"
  done
  echo
}

tput setaf 4
echo "Collecting the BSSIM traces..."

printf "Please enter the BSS Id: "
read BSSId

dots 10 2 &
dotID=$!

cd /alcatel/var/maintenance/trace
cp bssim_$BSSId.trace /alcatel/var/share/AFTR/MISC/MX_DATA/BSSIM
cd /alcatel/var/maintenance/hist
cp bssim_$BSSId.trace.old.$shortdate.* /alcatel/var/share/AFTR/MISC/MX_DATA/BSSIM
tput sgr0

kill "$dotID" 2>/dev/null

I have tried your code but i didn't work, the dot started on a new line not on the same line of "Collecting BSSIM traces ..." and i didn't see the word "done" when the copy was complete (code attached), below is the o/p:

axadmin@RTSCV490:/alcatel/var/share/AFTR/MISC/Midany$./dots_test
Please enter the occurrence date (YYYYMMDD): 20100322
Collecting the BSSIM traces...
Please enter the BSS Id: 1
.You have new mail in /var/mail/axadmin

Code:
tput setaf 4
printf "Collecting the BSSIM traces...\e7\n"

printf "Please enter the BSS Id: "
read BSSId

printf '\e8'

Try \e[s and \e[u instead of \e7 and \e8.

If those don't work, your terminal probably doesn't support saving and restoring the cursor.
