This might work if the editor in question is indeed holding open the file. Most times this is perhaps the case but if i remember correctly some editors create a temporary file, work on this tempfile and only finally overwrite the original with the changed copy destroying the temp. In this (admittedly - probaby quite rare -) case one wouldn't see that in fuser.

I suppose there is no 100% sure method for this and using fuser is IMHO as close as it gets. But if you already know which editor(s) you want/need to deal with you could put a PID-file or some other marker somewhere and hold other processing as long as the marker remains.

I hope this helps.

Name
       edquota - edit user quotas

Syntax
       edquota [ -p proto-user ] users...

Description
       The  command  is  a quota editor.  You can specify one or more users on the command line.  For each user, creates  a temporary file with an
       ASCII representation of the current disc quotas for that user and an editor is then invoked on the file.  You can then modify  the  quotas,
       add new quotas, and so forth.  Upon leaving the editor, reads the temporary file and modifies the binary quota files to reflect the changes
       made.

       If a valid quota file does not exist, refers the user to The user then has the option of either supplying the command  which  automatically
       creates the necessary quota file, or creating an empty quota file by various other means.

       If  the	option	is specified, duplicates for each user, the quotas of the prototypical user specified. This is the usual mechanism used to
       initialize quotas for groups of users.

       The editor invoked is unless the environment variable EDITOR specifies otherwise.

       Only the superuser can edit quotas.

Diagnostics
