Thanks Richard and Ernest
Both replies have helped me progress a little bit!
I am now at the point where the script will take user input to identify the
target folder (which contains the video files), plays them sequentially using
VLC and then closes cleanly once all files have been played. Here is the script
so far:
#!/bin/bash
#Allows user to select target directory
read -p "Enter path to target directory: " PATH
echo $PATH
#Deals with spaces in filenames
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")
#Sets "FILES" variable to all files (*) in "$PATH"
FILES=$PATH/*
#Runs "vlc" command on each file
for f in $FILES
do
echo "Processing $f file..."
/usr/bin/vlc --quiet --play-and-exit $f
done
#Closes IFS
IFS=$SAVEIFS
Finding the files is not an issue as they have been exported from their source
using other software and placed in the target directory ready for processing.

There is not really much to expand on. For my work I have a need to view the
contents of <x> number of videos and then, depending upon the nature of their
content grade them according to a numeric scale (1-9). Ideally I would want to
capture at least the file name, path and the grade applied and write that data
to a comma separated format for viewing in a spreadsheet at a later stage.
There are a number of scenarios that could happen when viewing and grading the
files that I would like to resolve:
1) Be able to apply a grade to a movie while it is playing. This action would
stop the current movie and open the next;
2) To replay a movie before applying a grade if desired;
3) Be able to pause the viewing process during its run if desired;
4) Stop the run completely but save progress so that it can be started again
from the same point at a later date.
There are probably many more such scenarios that I will think of as I progress
through the project.
> Ernest - "There might be a better solution for that than bash..."
Yes, I think you are probably correct in that statement, and I have started to
look at other languages to learn to try and get the project working. Although I
think it could be done using bash it wouldn't be very pretty. This started as a
quick and dirty script to automate a process that on the face of it seemed
fairly straight forward. It has turned into a bit of a personal challenge with
the side benefit of teaching myself a lot about bash scripting that I didn't
know before.
I am conscious that this is not a "coding" list and this thread is rapidly
moving off topic so I won't elaborate further, other than to say that I would
certainly be very interested in seeing some talks on programming at the monthly
meetings if there are any decent coders amongst us.
Alternatively, if there are any coders on the list who would be willing to
puppy walk me through this project as a learning exercise (I'm not fussy about
the language as long as it can run on Linux) then I would be more than happy to
buy the beers for the duration of the lessons.
Thanks Again
Stu

find (and xargs) might be a good choice for listing files as it can
handle weird filenames better [1]. The below will look for all the
files inside /path and execute rm on each one of them individually:
find /path -type f -exec rm '{}' +

looking at vlc's help [2], the --play-and-exit argument might be just
what you're looking for (I haven't tested this)

Would you care to expand on what it is that you are trying to achieve?
There might be a better solution for that than bash...
