Top Forums Shell Programming and Scripting Bash to add portion of text to files in directory using numerical match Post 302995164 by cmccabe on Sunday 2nd of April 2017 11:59:42 AM

That fixed it, but now I have the same problem I did before. The bash, as is works great as long as all 3 files are in the directory /home/cmccabe/QC/percent.

Since I run a process on each file, after it gets renamed it is moved to the directory. When the next filename gets renamed, the other one gets duplicated. If there is a third the first filename repeats 3 times the second filename duplicated and third is fine.

So if in /home/cmccabe/QC/percent

Code:
00-0000_Last-First_fbn1.txt

code executes a second time:
Code:
00-0000_Last-First_Last-First_fbn1.txt  ---- file already in dir
01-0101_LastN-FirstN_fbn1.txt

code executes a third time:
Code:
00-0000_Last-First_Last-First_Last-First_fbn1.txt  ---- file already in dir
01-0101_LastN-FirstN_LastN-FirstNfbn1.txt   --- this is the 2nd file in dir
02-0202_La-Fi_fbn1.txt

Maybe I just need to only execute the command once after all 3 files are in the directory? If a file is in the directory already it has been renamed already but I'm not sure how to prevent the duplication. Thank you Smilie.

NAME
syslogout - modular centralized shell logout mechanism DESCRIPTION
syslogout is a generic approach to enable centralized shell logout actions for all users of a given system in a modular and centralized way mostly aimed at avoiding work for lazy sysadmins. It has only been tested to work with the bash shell. It basically consists of the small /etc/syslogout shell script which invokes other small shell scripts having a .bash suffix which are con- tained in the /etc/syslogout.d/ directory. The system administrator can drop in any script he wants without any naming convention other than that the scripts need to have a .bash suffix to enable automagic sourcing by the /etc/syslogout script. For shell sessions, the contents of /etc/syslogout.d/" will be sourced by every user at logout if the following lines are present in his $HOME/.bash_logout: if [ -f /etc/syslogout ]; then . /etc/syslogout fi If used for X sessions it is advisable to include the former statement into the Xreset script of the X display manager instead to prevent that closing of an terminal emulator window yields unexpected results in your running X session if your X11 terminal emulator is using a login shell. Be sure then to run it under the user-id of the X session's user. See the example files in /usr/share/doc/syslogout/ for illustration. Users not wanting /etc/syslogout to be sourced for their environment can easily disable it's automatic mechanism. It can be disabled by simply creating an empty file called $HOME/.nosyslogout in the user's home directory using e.g. the touch(1) command. Any single configuration file in /etc/syslogout.d/ can simply be overridden by any user by creating a private $HOME/.syslogout.d/ directory which may contain a user's own version of any configuration file to be sourced instead of the system default. It's names have just to match exactly the system's default /etc/syslogout.d/ configuration files. Empty versions of these files contained in the $HOME/.syslo- gout.d/ directory automatically disable sourcing of the system wide version. Naturally, users can add and include their own private scripts to be automagically executed by /etc/syslogout at logout time. OPTIONS
There are no options other than those dictated by shell conventions. Anything is defined within the configuration scripts themselves. SEE ALSO
The README files and configuration examples contained in /usr/share/doc/syslogout/ and the manual page for bash(1), xdm(1x), xdm.options(5), and wdm(1x). Recommended further reading is everything related with shell programming. If you need a similar mechanism for executing code at login time check out the related package sysprofile(8) which is a very close compan- ion to syslogout. BUGS
syslogout in its current form is mainly restricted to bash(1) syntax. In fact it is actually a rather embarrassing quick and dirty hack than anything else - but it works. It serves the practical need to enable a centralized bash configuration until something better becomes available. Your constructive criticism in making this into something better" is very welcome. Before i forget to mention it: we take patches... ;-) AUTHOR
syslogout was developed by Paul Seelig <pseelig@debian.org> specifically for the Debian GNU/Linux system. Feel free to port it to and use it anywhere else under the conditions of either the GNU public license or the BSD license or both. Better yet, please help to make it into something more worthwhile than it currently is. SYSLOGOUT(8)
