I’m having trouble using the regex of the find command. Probably something I don’t understand about escaping on the command line.
Why are these not the same?
find -regex '.*[1234567890]'
find -regex '.*[[:digit:]]'
Bash, Ubuntu
Regular expressions with character classes (e.g.
[[:digit:]]) are not supported in the default regular expression syntax used byfind. You need to specify a different regex type such asposix-extendedin order to use them.Take a look at GNU Find’s Regular Expression documentation which shows you all the regex types and what they support.
