Not quite clear what exactly you are doing there; please give more info. Using leafpad to open / edit a file:
Code:
pgrep -xf "leafpad file1"; echo $?
6200
0
pgrep -xf "leafpad file1"; echo $?
1

First is with open file, second after closing it.

NAME
kate - Advanced text editor for KDE SYNOPSIS
kate [-s, --start name] [-u, --use] [-p, --pid pid] [-e, --encoding name] [-l, --line line] [-c, --column column] [-i, --stdin] [KDE Generic Options] [Qt Generic Options] DESCRIPTION
Kate is the KDE Advanced Text Editor. Kate also provides the editor part for various applications, under the name KWrite. Some of Kate's many features include configurable syntax highlighting for languages ranging from C and C++ to HTML to bash scripts, the ability to create and maintain projects, a multiple document interface (MDI), and a self-contained terminal emulator. But Kate is more than a programmer's editor. Its ability to open several files at once makes it ideal for editing UNIX(R)'s many configura- tion files. This document was written in Kate. OPTIONS
-s, --start name Start Kate with a given session. -u, --use Use an already running Kate -p, --pid pid Only try to reuse kate instance with this pid -e, --encoding name Set encoding for the file to open You can use this to force a file opened in utf-8 format, for instance. (The command iconv -l provides a list of encodings, which may be helpful to you.) -l, --line line Navigate to this line -c, --column column Navigate to this column -i, --stdin Read the contents of stdin SEE ALSO
More detailed user documentation is available from help:/kate (either enter this URL into Konqueror, or run khelpcenter help:/kate). There is also further information available at the Kate website: http://kate.kde.org/. EXAMPLES
To open a file named source.cpp at column 15, line 25, in an existing Kate window, you could use: kate -c 15 -l 25 -u source.cpp If you have an active internet connection, you can take advantage of KDE's network transparency to open a file from an ftp site. If you do not have write permission on the remote server, the file will be opened read only and you will be prompted for a local filename to save to if you make changes. If you do have write permission, changes will be saved transparently over the network. kate ftp://ftp.kde.org/pub/kde/README_FIRST AUTHORS
The maintainer of Kate is Christoph Cullmann <cullmann@kde.org>. A comprehensive list of authors and contributors is available in the com- plete user manual mentioned above. AUTHOR
