Don't know about you, but i keep facing with one problem from time to time in MacOS X. Sometimes i try to delete or modify some files and i get
“Operation cannot be completed because the item “File” is in use” or “because the file is locked” message. It can be quite irritating for me, because i like to keep my Trash Bin empty and sometimes, i can't get it empty because some delete files are "used by other application". And recently i found a solution:
chflags -R nouchg /PATH/TO/DIRECTORY/WITH/LOCKED/FILES/ where:
chflags= change flags on files/folders such as "locked"
-R= recursive or for everything and follow directories within the specified directory
nouchg= means the file can be changed
/PATH/= of course is the path to the files you want to change. Something like:
~/Sites/mysite/directory/with/locked/files/works as well.
