Command to Search for Filenames Exceeding 143 Characters?

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).

Try:

find /your/path | grep -E '[^/]{143,}$'

If you've already got a locate db, it is very fast at this.

locate --regex '.*/[^/]{143,}$'
