Find + -printf + sort conflict?
Clash Royale CLAN TAG#URR8PPP
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"

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.
