I'm trying to write my first ever shell script, the OS is Raspbian. The code I have written must be executed whenever a certain database has been modified. The database resides on a Windows server to which I have a mount point, and I have no control over the Windows server at all so changing directory names is not an option unfortunately. Here is the script I have written to date:
Unfortunately, no matter what, the script ALWAYS equates to false. I have included the 'ls' commands in the script purely for debugging purposes so I can check the variable declaration is working correctly and also to verify dates on the files. So when I run the script, this is the output I receive:
So clearly the declaration for DB1 is working, as the ls command in the script succeeds, and the output also clearly shows that DB1 is indeed the newer of the 2 files, but for some reason the file age test fails. If I change the script to perform the test based on files that do NOT contain spaces in the path then it works as expected, so there is no error in the logic of the code, but clearly the spaces in the pathname are causing a problem.
I've been working on this for a few days now, and I've researched as much as I can but have hit a brick wall. Any help would be very much appreciated.
Thank you!
*** UPDATE ***
I re-wrote the script to point to files on the local server only, taking the CIFS share out of the equation, and IT WORKS! So it would appear that the problem is caused by the fact the database resides on a CIFS share, but why on earth would that be the case when the ls output clearly shows the file is accessible? Here is the mount information just incase it helps to shed some light on the problem:

NPM-RUN-SCRIPT(1)NPM-RUN-SCRIPT(1)NAME
npm-run-script - Run arbitrary package scripts
SYNOPSIS
npm run-script <command> [--silent] [-- <args>...]
alias: npm run
DESCRIPTION
This runs an arbitrary command from a package's "scripts" object. If no "command" is provided, it will list the available scripts.
run[-script] is used by the test, start, restart, and stop commands, but can be called directly, as well. When the scripts in the package
are printed out, they're separated into lifecycle (test, start, restart) and directly-run scripts.
As of ` https://blog.npmjs.org/post/98131109725/npm-2-0-0, you can use custom arguments when executing scripts. The special option -- is
used by getopt https://goo.gl/KxMmtG to delimit the end of the options. npm will pass all the arguments after the -- directly to your
script:
npm run test -- --grep="pattern"
The arguments will only be passed to the script specified after npm run and not to any pre or post script.
The env script is a special built-in command that can be used to list environment variables that will be available to the script at run-
time. If an "env" command is defined in your package, it will take precedence over the built-in.
In addition to the shell's pre-existing PATH, npm run adds node_modules/.bin to the PATH provided to scripts. Any binaries provided by
locally-installed dependencies can be used without the node_modules/.bin prefix. For example, if there is a devDependency on tap in your
package, you should write:
"scripts": {"test": "tap test/*.js"}
instead of
"scripts": {"test": "node_modules/.bin/tap test/*.js"}
to run your tests.
The actual shell your script is run within is platform dependent. By default, on Unix-like systems it is the /bin/sh command, on Windows it
is the cmd.exe. The actual shell referred to by /bin/sh also depends on the system. As of `
https://github.com/npm/npm/releases/tag/v5.1.0 you can customize the shell with the script-shell configuration.
Scripts are run from the root of the module, regardless of what your current working directory is when you call npm run. If you want your
script to use different behavior based on what subdirectory you're in, you can use the INIT_CWD environment variable, which holds the full
path you were in when you ran npm run.
npm run sets the NODE environment variable to the node executable with which npm is executed. Also, if the --scripts-prepend-node-path is
passed, the directory within which node resides is added to the PATH. If --scripts-prepend-node-path=auto is passed (which has been the
default in npm v3), this is only performed when that node executable is not found in the PATH.
If you try to run a script without having a node_modules directory and it fails, you will be given a warning to run npm install, just in
case you've forgotten.
You can use the --silent flag to prevent showing npm ERR! output on error.
You can use the --if-present flag to avoid exiting with a non-zero exit code when the script is undefined. This lets you run potentially
undefined scripts without breaking the execution chain.
