PostProcessing.sh and a ' in Show Name

[sub]

I did some more testing and it looks like this might be the answer and still preserve the single quote:

bash -c "'/var/opt/nextpvr/scripts/PostProcessing.sh' '/mnt/NextPVR/Recordings/Mister Rogers Neighborhood/Season 15/Mister Rogers Neighborhood.S15E12.ts' 671 2529 21 'Mister Rogers'\'' Neighborhood'" - note, it is single quote,backslash,single quote,single quote after Rogers - it's hard to see.

In my PostProcessing script I echo'd the $1 $2 $3 $4 $5 variables and this is the output:

/mnt/NextPVR/Recordings/Mister Rogers Neighborhood/Season 15/Mister Rogers Neighborhood.S15E12.ts 671 2529 21 Mister Rogers' Neighborhood

I've had another go at this for the next release, replacing 'single quote' characters with 'single quote, backslash, single quote, single quote'. I don't have a convenient show to test it on, but testing it in shell window looks like it'll do the job.

Thanks.  I'll give it a try when available.

I stumbled on to another "special case", this time with a show with an exclamation mark (!) in the show name.
I played around with some various scenarios and it looks like they need to be escaped much like the single quote.

Here is an example:

bash -c "'/var/opt/nextpvr/scripts/PostProcessing.sh' '/mnt/NextPVR/Recordings/Whats Happening'\!''\!'/Season 01/Whats Happening'\!''\!'.S01E18.The Tickets.ts' 674 2588 21 'What'\''s Happening'\!''\!''"

single quote, backslash,!,single quote - '\!'

This is probably a rare occurrence, but someone might run into this.

EDIT: I'm not entirely sure if this is necessary. When I run the bash command from a command shell prompt, there are issues with the exclamation marks, but it might not be a problem when called from the recording process because it recorded with the correct name - the only problem was the single quote when the PostProcessing script was called.

I'm not sure that one is necessary. Did you try recording that show, or this just going by the name?

I did record the show and it did save the recording as it it should:

Looking at it now, I think it probably will work fine.  I know there are some quirks with the exclamation mark and those might have been unique to calling the bash script from a command prompt.

Usually if a simple echo works for me, it'll work when NextPVR calls it:

Code:

[root@s152252 ~]# echo 'What'\''s Happening!!'
What's Happening!!

The example with the exclamation mark also has the single quote so not the best test. It's not clear why a string replace with \\' doesn't work with .net though.
