SVN. Update a single file without checking out the entire source tree

  • submit to reddit
# Empties current directory and extracts single file/folder from svn

    echo >&2 "$@"
    exit 1

usage=$"This scripts extract single file/folder from SVN repository into the current directory,\n\
allowing to modify it locally without extracting all other sibling files and directories\n\
$0 svn_uri\n\

[ "$#" -ge 1 ] || die "SVN URI is not provided. $usage"

# Testing is svn CLI is present
svnRun=`which svn 2> /dev/null`
if [ ! $svnRun ]
  die "svn CLI is not found on PATH"

# determine parent folder and file from the give URI

# remove .svn and the file if they exist
rm -rf .svn
rm -f $svnFile

# extract the file
svn checkout -q --depth=empty $svnParent .
svn update $svnFile

echo "\n\
After $svnFile is changed locally commit it using\n\
  svn commit -m \"your update description\""

Sometimes, especially when you work cross various projects, you need to modify a single file in a project. A good  example for this updating pom.xml by adding description, name, SCM or CI sections.

However majority of UI tools do not provide a possibility to extract a single file, avoiding checking out all its siblings recursively. Commands of CLI enable this, but they are not well known.

The idea is to checkout the containing folder with ‘empty’ depth and then update the file you are interested in. For simplicity of use, I wrote a shell script, which take the URI to the file is SVN, and extracts it to the current directory. The URI of the file can be copied from a browser. The script is also available in Bitbucket
