Find + -printf + sort conflict?
I need to pass a list of sorted, quoted FLAC file names to SoX for concatenation but am having trouble getting sort to work the way I expect it to.
If I use:
find . -maxdepth 1 -type f -iname "*.flac" | sort
I get exactly what I expect:
./01-Lordy.flac
./02-Both Sides Now.flac
./03-Solitary Man.flac
./04-Holly Holy.flac
./05-Cherry Cherry.flac
./06-Kentucky Woman.flac
./07-Sweet Caroline.flac
./08-Thank the Lord for the Nightime.flac
./09-And the Singer Sings His Song.flac
./10-Brother Loves Traveling Salvation Show.flac
However, I can't really use that for what I'm doing since I need a quoted list with no newlines. I know -printf can do that for me, but when I try:
find . -maxdepth 1 -type f -iname "*.FlAc" -printf ""%p" " | sort
I wind up with a list of file names that are quoted and separated by a single space (good!) but they aren't sorted (bad!). Or at least they aren't sorted the way I expect them to be:
"./08-Thank the Lord for the Nightime.flac" "./03-Solitary Man.flac" "./09-And the Singer Sings His Song.flac" "./05-Cherry Cherry.flac" "./06-Kentucky Woman.flac" "./10-Brother Loves Traveling Salvation Show.flac" "./07-Sweet Caroline.flac" "./02-Both Sides Now.flac" "./01-Lordy.flac" "./04-Holly Holy.flac"
Maybe even weirder, if I just for the sake of testing use the same code but add a newline:
find . -maxdepth 1 -type f -iname "*.FlAc" -printf ""%p" "\n | sort
The sort works even if the output is back to not being what I need:
"./01-Lordy.flac"
"./02-Both Sides Now.flac"
"./03-Solitary Man.flac"
"./04-Holly Holy.flac"
"./05-Cherry Cherry.flac"
"./06-Kentucky Woman.flac"
"./07-Sweet Caroline.flac"
"./08-Thank the Lord for the Nightime.flac"
"./09-And the Singer Sings His Song.flac"
"./10-Brother Loves Traveling Salvation Show.flac"

Do you have to usefindhere, for the recursion? Or are all the desired files in the same directory? (I ask, given the-maxdepth 1and the sample output indicating the same directory)

If you a) are using GNU sed and b) you really need to find your files recursively, you can use this:find . -iname '*.flac' -print0 | sort -z | xargs -0 sox ...instead of messing with quoting and unquoting.

If the files are all in the same directory, and you want to pass a list of sorted filenames to sox, then the bash shell could do that directly:
shopt -s nocaseglob
sox *.flac
The nocaseglob shell option allows the wildcard to pick up foo.FLAC, foo.Flac, foo.flaC, etc. The wildcard expands to an alphabetically sorted list, much like a bare sort would. It would, for example, put 9-file.flac after any filename that started with 8.
Thanks to @mosvy for a simplification of the above bash-ism into a wildcard that should work with any shell:
sox *.[Ff][Ll][Aa][Cc]
The brackets allow any combination of upper- and lower-case letters in the "flac" extension, in order to match what your find ... -iname "*.FlAc" was doing.

@atrocity In a directory where the files sort incorrectly, you might want to inspect the output ofprintf '%sn' *.[Ff][Ll][Aa][Cc]. This is the same order that would be given tosoxand should be sorted lexicographically — which is not the same as numerically if you have filenames that start with numbers with different numbers of digits

Thank you everyone.sox *.[fF][lL][aA][cC]looks like it works whileprintf '%sn' *.[Ff][Ll][Aa][Cc]looks like it gives me what I need to double-check that the order is correct.

@atrocity In a directory where the files sort incorrectly, you might want to inspect the output of
printf '%sn' *.[Ff][Ll][Aa][Cc]. This is the same order that would be given to sox and should be sorted lexicographically — which is not the same as numerically if you have filenames that start with numbers with different numbers of digits– Fox

Thank you everyone.
sox *.[fF][lL][aA][cC] looks like it works while printf '%sn' *.[Ff][Ll][Aa][Cc] looks like it gives me what I need to double-check that the order is correct.– atrocity

Do you have to use
findhere, for the recursion? Or are all the desired files in the same directory? (I ask, given the-maxdepth 1and the sample output indicating the same directory)– Jeff Schaller

I think what you're overlooking is that
sortsorts lines (or, with GNUsort -z, null-delimited elements) - it should be no surprise that it doesn't sort filenames when they're all on a single line– steeldriver

If you a) are using GNU sed and b) you really need to find your files recursively, you can use this:
find . -iname '*.flac' -print0 | sort -z | xargs -0 sox ...instead of messing with quoting and unquoting.– mosvy

@mosvy I was just experimenting with that idea; that seems like a good additional answer!

If you're trying to collect filenames to pass to SoX as command-line arguments, you do not want to put quotes around them. Quotes are parsed only when they're actually part of the command, not when they're in date (e.g. from a variable or command substitution). See here for an example.
