"svn ls" seems completely sufficient for this task. Here's a little
shell script you can save as "svnbranchexists":
if [ -z "$1" ]; then
echo "usage: $0 <branch>"
svn ls $BRANCH >/dev/null 2>&1
if [ 0 -eq $? ]; then
echo "branch $1 exists"
echo "branch $1 does not exist"
Here's examples of using it:
usage: ./svnbranchexists <branch>
$ ./svnbranchexists nonexistent
branch nonexistent does not exist
$ ./svnbranchexists 1.4.x
branch 1.4.x exists
To use it on your repo, put your repository URL into the REPO
This assumes you're on a Unix-like operating system. If you're on
Windows, you'll need to convert the script to a scripting language
that exists on Windows, or use Bash in Cygwin.
