So some background first: I am attempting to convert a non-encrypted shared folder into an encrypted one on my Synology NAS and am seeing this error:

So I would like to locate the offending files so that I may rename them. I have come up with the following grep command: grep -rle '[^ ]143,' * but it outputs all files with paths greater than 143 characters:

#recycle/Music/TO SORT/music/H/Hooligans----Heroes of Hifi/Metalcore Promotions - Heroes of Hifi - 03 Sly Like a Megan Fox.mp3
...

What I would like is for grep to split on / and then perform its search. Any idea on an efficient command to go about this (directory easily contains hundreds of thousands of files)?

command-line filenames synology

Although the GNU ‘findutils-default’ regular expression syntax doesn't provide a n,m interval quantifier, you can use a -regex test in GNU find if you select a different regextype, for example:

find . -regextype posix-extended -regex '.*/[^/]143,$'

or

find . -regextype egrep -regex '.*/[^/]143,$'

or

find . -regextype posix-basic -regex '.*/[^/]143,$'

etc. There may be other regextypes that support n,m intervals, either with or without escaping.

Compared to piping the results of find to a separate grep command, this will match across newlines (i.e. the find regex flavors differ from their namesakes in that . matches the newline character by default).
