Hi there! I'm developing a program that allows the user to open and edit files using both an editor and the terminal. Once the user has finished editing the file an update is sent to the logbook that compares the file before and after it was edited - this can only be done if the file is closed (I think) to guarantee the user is finished editing it. Currently I am checking if the file is closed like this:
This method does work but it isn't very effective as the if statement checks if ANY file is open in gedit - not the particular one the user has opened which is what I want to do. I played around with PID's and was unable to find a solution.

vipw
VIPW(8) BSD System Manager's Manual VIPW(8)NAME
vipw -- edit the password file
SYNOPSIS
vipw [-d directory]
DESCRIPTION
vipw edits the password file after setting the appropriate locks, and does any necessary processing after the password file is unlocked. If
the password file is already locked for editing by another user, vipw will ask you to try again later. The default editor for vipw is vi(1).
vipw performs a number of consistency checks on the password entries, and will not allow a password file with a ``mangled'' entry to be
installed. If vipw rejects the new password file, the user is prompted to re-enter the edit session.
Once the information has been verified, vipw uses pwd_mkdb(8) to update the user database. This is run in the background, and, at very large
sites could take several minutes. Until this update is completed, the password file is unavailable for other updates and the new information
is not available to programs.
The options are as follows:
-d directory
Change the root directory of the password file from ``/'' to directory.
If a vipw session is killed it may leave ``/etc/ptmp'', which will cause future vipw executions to fail with ``vipw: the passwd file is
busy'', until it is removed.
ENVIRONMENT
If the following environment variable exists it will be used by vipw:
EDITOR The editor specified by the string EDITOR will be invoked instead of the default editor vi(1).
FILES
/etc/master.passwd The current password file.
/etc/ptmp Temporary copy of the password file used while editing.
SEE ALSO chpass(1), passwd(1), pwhash(1), passwd(5), passwd.conf(5), pwd_mkdb(8), user(8)HISTORY
The vipw command appeared in 4.0BSD.
