Automating Subversion repository creation for new and imported repos.

Creating new repositories is a very mechanical operation ripe for automation. This bash script will create a new repository in the appropriate directory using the name specified on the command line. It will also set up the default Subversion paths of trunk, branches and tags. It checks for the Collabnet binaries to determine the unique settings needed for that implementation.

#!/bin/sh
 
REPOSITORIES="/var/svn/repositories"
 
# Set variables based on Collabnet vs. other install
if [ -f "/opt/CollabNet_Subversion/bin/svn" ]
then
  BIN_DIR="/opt/CollabNet_Subversion/bin"
  APACHE="csvn:csvn"
else
  BIN_DIR="/usr/bin"
  APACHE="apache:apache"
fi
 
function errormsg
{
  echo "$0: missing operand"
  echo "Usage: $0 RESPOSITORY..."
  echo "Create the RESPOSITORY(s)."
}
 
function is_valid_posix_filename
{
  # Return TRUE if characters in $1 confirms to posix, else FALSE.
  len=`echo "$1"| wc --chars`
  if [ $len -le 255 ]; then
    fs=`echo "$1"| grep '/'`
    if [ -z "$fs" ]; then
      return 1
    fi
