Quoted By:

please write a regex that can capture any line that this one can
>^[^ \t\v\f\r\n]+$
except that also '[' and ']' must be excluded EXCEPT if they are escaped.

It should be:
>^(?:\\[[\]]|[^ \t\v\f\r\n[\]])+$

Now I need to rework this one
>(?:^ {0,3}[^ \t]+$)
So it can contain whitespace, but it must have at least one non-whitespace. Help pls.

You should explain what you want better, because [^ \t]+ already ensure it has non-space non-tab character.

Whitespace is also \r and \n .

If you are concerned about other white space characters:
^(?=.*\S) {0,3}[^ \t]+$
You didn't specify where in the regexp, so it can be anywhere.
>>714287
And that regexp start with (?:^ and end with $) is wrong, (?: ) means non capture group, grouping here is useless.

I could use some help with a bash/ffmpeg command and I cant into regex.
Basically, I need to write the filename of a bunch of videos into their respective Title metadata.
The filenames are formatted like this,
200_SG1_S10D4-Episode.m4v
and I want the metadata Title to be the same. I found another guy's work but his filename format was different,
Bleach - 001 - A Shinigami Is Born!.avi
Here was his solution:
or file in *; do newname=${file:0:-4}_2 ext=${file##*.} filename=${file} showname=${file%% *} episode=${file:9:3} nameext=${file##*- } title=${nameext%.*}; ffmpeg -i "$filename" -metadata title="$title" -metadata track=$episode -metadata album=$showname -c copy "$newname.$ext"; mv -f "$newname.$ext" "$filename"; done
Can this be adapted to work with mine?
Shitty gimp mockup OC as appreciation.

Normally I would told you to go fuck yourself, but because Stargate shows you have good taste, I'll try to help ya. (Making a circle in gimp is quite impressive too.)
Most of the another's guys command is about splitting episode name to series, episode, file extension etc., if you want to just put filename into metadata title, it's much simpler.
>for file in *; do ffmpeg -i "$file" -metadata title="$file" -c copy "$file.tmp"; mv -f "$file.tmp" "$file"; done
Hopefully this is right, I didn't test it, so be careful.

Many thanks, anon. I'll give it try on a test directory and report back.

Ok, I tried it but each file gets this error:
[NULL @ 0x56425b86b560] Unable to find a suitable output format for '192_SG-1_S9D5-Camelot.m4v.tmp'
192_SG-1_S9D5-Camelot.m4v.tmp: Invalid argument
mv: cannot stat '192_SG-1_S9D5-Camelot.m4v.tmp': No such file or directory
I'm guessing some issue with trying to hold these files in temp?

maybe either a way to move the new file to a new directory or to prepend each new file with a character like "n" so I can sort old from new?

Sorry, apparently ffmpeg decides file format according to file extension, which I broke by using tmp as temporary extension. Try this instead:
>for file in *; do ffmpeg -i "$file" -metadata title="$file" -c copy "tmp-$file"; mv -f "tmp-$file" "$file"; done

YOU DID IT! Thank you so much, anon. You saved me so much time and hassle. I wish I could personally shake your hand. Now, I can start setting up a proper playlist. From S8 onward of SG-1 the episodes aired with Atlantis so proper watching order is to alternate between the two. Swapping discs every episode is a pain but also hard on the discs.
Again, thanks from me and my stargate collection.

Dammit. This brings so many memories (even though I've already forgotten so much) that I've nearly shed a tear. I gotta rewatch it too.
