This command will add any un-versioned files listed in svn st command output to subversion.

Note that any filenames containing whitespace in the svn stat output will not be added. Further, odd behavior might occur if any filenames contain '?'s.

svn st | grep ? | tr -s ' ' | cut -d ' ' -f 2 | xargs svn add

or if you are good at awk:

svn st | grep ? | awk '{print $2}' | xargs svn add

Explanation:

Step 1: svn st command

[user@xxx rails]$svn st?       app/controllers/application.rbM       app/views/layouts/application.html.erb?       config/database.yml

Step 2: We grep the un-versioned file with grep command:

[user@xxx rails]$svn st | grep ??       app/controllers/application.rb?       config/database.yml

Step 3: Then remove the squeeze the space between ? and file path by using tr command:

[user@xxx rails]$svn st | grep ? | tr -s ' '? app/controllers/application.rb? config/database.yml

Step 4: Then select second column from the output by using cut command:

[user@xxx rails]$svn st | grep ? | tr -s ' ' | cut -d ' ' -f 2app/controllers/application.rbconfig/database.yml

Step 5: Finally, passing these file paths as standard input to svn add command:

[user@xxx rails]$svn st | grep ? | tr -s ' ' | cut -d ' ' -f 2 | xargs svn addA       app/controllers/application.rbA       config/database.yml
