[gentoo-user] look for a file type + sort

[gentoo-user] look for a file type + sort

[Joseph]

I want to list recursively certain type of files eg. *.pdf 
but I want to display: date, path and newest file first.

What is the easiest way of doing it?

ls -l --sort=time "$(find /path -iname "*.pdf")"

If there are no spaces in the filenames/directories, you can drop the
quotes from $().

Sorry, it doesn't work with spaces even with the quotes; if you don't
have spaces in the directories/filenames, do

ls -l --sort=time $(find /path -iname "*.pdf")

If you have spaces, you need to set/restore IFS:

S=${IFS}; IFS=$'\n'; ls -l --sort=time $(find . -iname "*.pdf"); IFS=${S}

Hm, I've tried:
ls -l --sort=time $(find /home/joseph -iname "*.jpg")

got:
ls: invalid option -- '/'

The exact same command (changing joseph with canek) works for me,
except in directories/filenames with spaces, as expected. Do you have
an alias for ls? What does find /home/joseph -iname "*.jpg" returns?

Hi,

This one should work:

find /home/joseph/ -iname "*.pdf" -exec ls -l --sort=time {} +

This won't work if there are too many files because find will eventually
start ls multiple times.

Try this instead:
find /path -iname '*.pdf' -printf '%T@\t%Tc\t%p\n' | sort -nr |
cut -f 2-

They both work thank you! 
But Florian solution seems to work better eg.

Solution 1:
find /home/joseph/ -iname "*.jpg" -exec ls -l --sort=time {} + |more
-rw-r--r-- 1 joseph users  113350 Aug 16 20:11 /home/joseph/business/Drawings/tolsink_devices/Fostex-HP-P1_to_Ibasso-D12_2.6cm_c2c_69deg.jpg

...

Solution 2.
find /home/joseph -iname '*.jpg' -printf '%T@\t%Tc\t%p\n' | sort -nr | cut -f 2- |more

The first solution did not find the first 5-files showing up in the Solution 2.

-exec is not suitable here because it spawns a `ls` process per each 
found entry; aside from being slow, this disallows sorting at all.
You'd prefer
find /home/joseph/ -iname "*.pdf" |xargs ls -l --sort=time

or, to be space-proof
find /home/joseph/ -iname "*.pdf" -print0 |xargs -0 ls -l --sort=time

A little late but HTH.

This is incorrect. If you terminate exec with '+' instead of '\;', only a single
instance of the command is run - the command line is built by appending
each found file to the end of the {} placeholder.

The only reason I see for it to fail is if you have so many files that
it can't be
passed to the argv of the receiving command.

Sorry, I'm ashamed
I didn't know about this feature. Does it also handle spaces correctly?

There's always an opportunity to use tempfiles ;)

Perhaps not the most elegant solution.

ls -lt `du -a|grep -i '\.pdf$'|awk '{ print $2 }'`|awk '{ print 
$6,$7,$8,$9,$10,$11 }'

I'm not sure how the internals work. As best as I can guess, it constructs
the argv directly so spaces shouldn't be an issue. Spaces are an issue when
the output is piped through, since the pipe itself knows no difference
between filename and output spaces, hence the need to force zero delimiters
between filenames. Since find runs the command directly, you shouldn't
encounter this. But Ive yet to test.

Your assumption is correct. exec cannot be fooled with whitespaces.
