Linux Read file and skip the line starting with #
Hi all,
I'm new in unix. Need some help here.

I have a file called server.cfg which contains the servers name, if I don't want to run on that server, I'll put a "#" infront it.
Code:
username1@hostname.com
username2@hostname.com
#username3@hostname.com
#username4@hostname.com
username1@hostname.com

and I need to retrieved them to run a script to copy file to the servers.
here is my script.
Code:
#!/usr/bin/sh
file2put=$1
if [ -f $file2copy ]
then
 echo "File found, preparing to transfer... \n"
 
  grep -v '^#' | while read line 
  do
   ssh $line < checkdirectory.sh #another script to check the existing of directory
  scp $file2put $line:~/folder_name/$file2copy
 done < server.cfg
 exit
 else
  echo "File does not exist. Exiting..."
  exit 
fi

The problem is that it won't skip the server that start with a "#". I had search the similar thread such as [how to skip the line starting with "#"] etc, and I try to use the 'grep' function but it won't solve my problem.

Fyi,
my operating system : SunSolaris

Anyone can help on this? Sorry for my poor of English.

Thanks in advanced.

debconf-updatepo

DEBCONF-UPDATEPO(1)						    po-debconf						       DEBCONF-UPDATEPO(1)

NAME

       debconf-updatepo - update PO files about debconf templates

SYNOPSIS

       debconf-updatepo [-v] [-h] [--podir=DIR] [--skip-pot] [--skip-merge] [--msgid-bugs-address=EMAIL]

DESCRIPTION

       This program reads po/POTFILES.in to determine which master files need to be processed, then extracts new gettext strings into
       po/templates.pot and updates all po/*.po files.	This script can be called either in the top-level directory, or in the debian or debian/po
       subdirectories.	It is run by developer and/or translator to update PO files when the English text is modified in templates files.

OPTIONS

       -h, --help
	   Display a usage summary and exit.

       -v, --verbose
	   Process in verbose mode.

       --podir=DIR
	   Set directory for PO files.	By default PO files are searched in debian/po, po and ../po directories in that order.

       --skip-pot
	   Do not generate a new po/templates.pot file.

       --skip-merge
	   Do not merge existing PO files with po/templates.pot.

       --msgid-bugs-address=EMAIL
	   Set the email address that will be specified in the POT's Report-Msgid-Bugs-To field.

	   By default, this field is set to <package>@package.debian.org.

	   It is intended for the maintainers of Debian based distributions, and should be used in the following cases:

	   o   The package is not present in Debian (and thus the <package>@packages.debian.org address does not exist).

	   o   The maintainer made significant changes in the debconf templates (or added templates to a Debian package without templates), and
	       does not want to bother the Debian maintainer with bug reports that won't be relevant for the Debian maintainer.

	   The default address is preferred to avoid corrections in the Debian based distribution without a notification to the Debian maintainer.
