How do I create a for loop that only executes on files larger than a specified filesize?-CodePudding

I want to split mp4 files that are greater than 500MB into segments smaller than 500MB.

How do I create a for loop to iterate over a directory of files, running

mp4box -splits 500000 input.mp4

on each file greater than 500 MB?

(The loop part is not a problem. The testing for filesize part is.)

CodePudding user response：

You can use find for this:

find ./ -name "*.mp4" -size  500M -exec mp4box -splits 500000 {} \;

(I didn't test it, but it should be something like that)

CodePudding user response：

With zsh:

for f ( *.mp4(.Lk 500000) ) mp4box -splits 500000 $f

Glob qualifiers: (.) to match plain files, (Lk 500000) to match files greater than 500000 KB in size. Add (D) to the qualifiers to include dotfiles.

CodePudding user response：

You can perhaps use find, e.g.:

for file in $( find . -size  500M )
do
    echo $file
done

But I don't know if find is available with macos.

CodePudding user response：

you can use stat

for example :- stat filename.txt

note: it shows the size in bytes
