[Bug 1261880] Re: apt-get flushes read buffer

[Cliff Carson]

No activity on this bug report.  Was wondering if it is valid to call
apt-get within as scripts read file loop?  I have changed the script to
read the file into a local variable products and use a "for products in
$productlist" to loop through the calls to "apt-get install $product".

Title:
  apt-get flushes read buffer

Status in “apt” package in Ubuntu:
  New

Bug description:
  Have a script that installs all the additional programs (chromium-
  browser, glabel, gimp,,,, etc) after installing the base 14.04 system.
  Have used this same script for many relase of Ubuntu.  When I run it
  now it appears that the first call to apt-get will purge the read
  buffer on the script.  Example of the script

  while read cmdtodo prodtoinst
    do
      apt-get -y $cmdtodo $prodtoinst
  done < $infile

  The infile contains a list of commands and products

  remove rythmbox
  install glabel
  install gimp
  install gnucash

  What I see at the terminal after calling the user install script is
  the output of apt-get remove rythmbox and then the rest of the lines
  in the infile (the "install glabel"  "install gimp" etc get outputed
  to the terminal before the completion of the apt-get remove command.
  The installs stop.

  If the user command is immediately re-run the first product fails
  because it is either installed or uninstalled and the next product is
  picked up and run.  Again during the run the infile buffer is flushed
  to the terminal and the installs stop.
