lsof command

we can use losf for this problem .if using this command we can find out whoever opened the wich files also we can find based on the username and login anme etc..


lsof -c names -u ^user

the above command used for show the files are opened by processess whose names startes with "names", but exclude those whose owner is the user "user".

we can have more options in lsof command (-t,nl,-u,-c..etc)

PPI::Document::File(3)					User Contributed Perl Documentation				    PPI::Document::File(3)

PPI::Document::File - A Perl Document located in a specific file DESCRIPTION
WARNING: This class is experimental, and may change without notice PPI::Document::File provides a PPI::Document subclass that represents a Perl document stored in a specific named file. METHODS
new my $file = PPI::Document::File->new( '' ); The "new" constructor works the same as for the regular one, except that the only params allowed is a file name. You cannot create an "anonymous" PPI::Document::File object, not can you create an empty one. Returns a new PPI::Document::File object, or "undef" on error. filename The "filename" accessor returns the name of the file in which the document is stored. save # Save to the file we were loaded from $file->save; # Save a copy to somewhere else $file->save( '' ); The "save" method works similarly to the one in the parent PPI::Document class, saving a copy of the document to a file. The difference with this subclass is that if "save" is not passed any filename, it will save it back to the file it was loaded from. Note: When saving to a different file, it is considered to be saving a copy and so the value returned by the "filename" accessor will stay the same, and not change to the new filename. TO DO
- May need to overload some methods to forcefully prevent Document objects becoming children of another Node. SUPPORT
