Capitalize every file in a directory, in bash, using 'svn mv'

Question
I need to change the capitalization of a set of files in a subversion working copy, like so:
svn mv test.txt Test.txt svn mv test2.txt Test2.txt svn mv testn.txt Testn.txt ... svn commit -m "caps"
How can I automate this process? Standard linux install tools available.
Solution
ls | awk '{system("svn mv " $0 " " toupper(substr($0,1,1)) substr($0,2))}'
obviously, other scripting languages will work just as well. awk has the advantage that it it ubiquitous.
OTHER TIPS
If you have a decent install you should have python, give this a try:
#!/usr/bin/python
from os import rename, listdir
path = "/path/to/folder"
try:
dirList = listdir(path)
except:
print 'There was an error while trying to access the directory: '+path
for name in dirList:
try:
rename(path+'\\'+name, path+'\\'+name.upper())
except:
print 'Process failed for file: '+name
I don't think theres an easy way to do it with bash/sed/tr/find.
I'd make a Ruby/Perl script that does the renaming.
#!/usr/bin/ruby
# Upcase.rb
ARGV.each{ |i|
newname = i.gsub(/(^.|\s.)/{ |x| x.upcase }
`svn mv "#{i}" "#{newname}" `
}
Then just do
./Upcase.rb foo.txt test.txt test2.txt foo/bar/test.txt
or if you want to do a whole dir
find ./ -exec ./Upcase.rb {} +
Please note that this change breaks existing workingcopies on Windows and Mac systems, as they can't handle case only renames.
I typically do this by redirecting the 'ls' output to a file, using vim macros to massage each filename into the command line I want, then execute the file as a shell script. It's crude but effective.
