How to randomize a list?
Vlad Ghitulescu
I have a list of difficult words / phrases for my son (see below) that I
want to randomize in order to keep the boy awake :-)
I've found similar (old!) questions:
http://bbedit-talk.barebones.narkive.com/jXrdz0T6/randomize-lines
https://stackoverflow.com/questions/2153882/how-can-i-shuffle-the-lines-of-a-text-file-on-the-unix-command-line-or-in-a-shel

https://superuser.com/questions/760732/randomly-shuffle-rows-in-a-large-text-file
but I couldn't find out how to make them work in BBEdit (so I ended
using http://www.randomizelist.com until I get a hint from you ;-).
Could you please help me?
Thanks!

Vlad

Make a text filter called Randomize with the contents:
#!/bin/sh
exec shuf
Text filters go in ~/Library/Application Support/BBEdit/Text Filters. I think they probably have to be executable. Running these command in Terminal should do the trick:
cd ~/Library/Application\ Support/BBEdit
mkdir -p Text\ Filters
cd Test\ Filters
echo -e "#!/bin/sh\necho shuf" > Randomize
chmod +x Randomize
You should then see it in the “Apply Text Filter” submenu of the “Text” menu.
Hope this helps!

sort -R seems to be available in recent versions of macOS (the man page indicates a 2015 date).
There is also a solution with Perl as given here:

Hi, Sam!
Thanks for the explanations & reminder (I think Chris was so nice to show me this once - because I still have two TextFilters - but I didn't use it since then and I've forgot :-((()
It seems that shuf is not there, because everything I've got is this error message:
/Application Support/BBEdit/Text Filters/Randomize.sh: line 2: exec: shuf: not found
that replace my active list :-)
I'll try it now with sort -R and report the results.
Until next time,
Vlad

Hi, Jean-Christophe!
sort -R brings this error message:
sort: invalid option -- R
Try `sort --help' for more information.
and sort --help brings this:
--
Vlads27iMac2012:~ Vlad$ sort --help
Usage: sort [OPTION]... [FILE]...
Write sorted concatenation of all FILE(s) to standard output.
Mandatory arguments to long options are mandatory for short options too.
Ordering options:
-b, --ignore-leading-blanks ignore leading blanks
-d, --dictionary-order consider only blanks and alphanumeric characters
-f, --ignore-case fold lower case to upper case characters
-g, --general-numeric-sort compare according to general numerical value
-i, --ignore-nonprinting consider only printable characters
-M, --month-sort compare (unknown) < JAN' < ... <DEC'
-n, --numeric-sort compare according to string numerical value
-r, --reverse reverse the result of comparisons
Other options:
-c, --check check whether input is sorted; do not sort
-k, --key=POS1[,POS2] start a key at POS1, end it at POS2 (origin 1)
-m, --merge merge already sorted files; do not sort
-o, --output=FILE write result to FILE instead of standard output
-s, --stable stabilize sort by disabling last-resort comparison
-S, --buffer-size=SIZE use SIZE for main memory buffer
-t, --field-separator=SEP use SEP instead of non-blank to blank transition
-T, --temporary-directory=DIR use DIR for temporaries, not $TMPDIR or /tmp;
multiple options specify multiple directories
-u, --unique with -c, check for strict ordering;
without -c, output only the first of an equal run
-z, --zero-terminated end lines with 0 byte, not newline
--help display this help and exit
--version output version information and exit
POS is F[.C][OPTS], where F is the field number and C the character position
in the field. OPTS is one or more single-letter ordering options, which
override global ordering options for that key. If no key is given, use the
entire line as the key.
SIZE may be followed by the following multiplicative suffixes:
% 1% of memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.
With no FILE, or when FILE is -, read standard input.
*** WARNING ***
The locale specified by the environment affects sort order.
Set LC_ALL=C to get the traditional sort order that uses
native byte values.
Report bugs to bug-co...@gnu.org.

So sorry for leading you astray with shuf. I’ve had GNU Coreutils installed for so long that I’ve forgotten what’s in stock macOS.
It sounds like your sort is too old to have -R.
Jean-Christophe’s Perl solution would probably be easiest at this point.
Try replacing the contents of your “Randomize” text filter with:
#!/usr/bin/env perl
use List::Util 'shuffle';
print shuffle(<STDIN>);
Hope this helps!

Yes, that helped indeed!
That worked even whitout making the file Randomize.sh executable with chmod +x Randomize!
Take a look:

-rwxr-xr-x@ 1 Vlad staff 80 4 Nov 2015 Selection_To_Numbered_List.sh
How is this possible?
Anyway: Thanks again!

I never used sort -R before, but as I wrote the manual has 2015 as a date and Sierra was released in 2016, so I guess Apple saw fit to upgrade sort for High Sierra.
Would you mind checking the date at the end of the sort man page on your machine?

They provide roughly the same functionality as the standard UNIX utilities that come with macOS. (Which come from a BSD lineage.) I like them because I used Linux for years and get tripped up by the differences in the command-line interfaces. If you don’t have this problem, then I don’t think there’s a good reason to install the GNU versions.
The Perl solution should be fine for your purposes. It will randomize correctly (unlike sort -R, which actually sorts by an arbitrary, but not random, characteristic of the data), and performance should be acceptable.
That worked even whitout making the file Randomize.sh executable with chmod +x Randomize!
Take a look:
Vlads27iMac2012:Text Filters Vlad$ ls -al
total 48
drwxr-xr-x@ 5 Vlad staff 170 14 Jan 21:17 .

-rwxr-xr-x@ 1 Vlad staff 80 4 Nov 2015 Selection_To_Numbered_List.sh
How is this possible?
See the x in column 4? That indicates that Randomize.sh is in fact executable, by the owner (you). BBEdit also runs as you, so it can execute the script just fine.
Just a note: BBEdit doesn’t care, but to avoid future human confusion you might want to change Randomize.sh to Randomize.pl since it’s a Perl script now.

I've kept the best of both worlds and added -sw to Sam's Randomize.

How come that the others have an x on column 7 and Randomize.sh not?
They were all created and stored in BBEdit!

:) High Sierra ?
:-D
You're right, didn't even came to mind due to
a) iMac late 2012 with
b) FusionDrive and
c) learning about the disadvantages of APFS for non-SSDs.
I never used sort -R before, but as I wrote the manual has 2015 as a date and Sierra was released in 2016, so I guess Apple saw fit to upgrade sort for High Sierra.

OH!
That's pretty old:

The full documentation for sort is maintained as a Texinfo manual. If the info and sort programs are properly installed at your site, the command
info sort
should give you access to the complete manual.
sort 5.93 November 2005 SORT(1)
Ok, I'll wait for the next one and the reconsider homebrew! :-)
Thanks!

Also, besides for the command line tools, you also have access to full .app applications that are also available as brew packages.
