Question

I want to select some files that are matching a regular expression.
Files are for example:

4510-88aid-50048-INA.txt
4510-88nid-50048-INA.txt
xxxx-05xxx-xxxxx-INA.txt

I want all files that match this regex:

.*[\w]{4}-05(?!aid)[\w]{3}-[\w]{5}-INA\.txt

In my opinion this have to be xxxx-05xxx-xxxxx-INA.txt in the case above.
Using some tool like RegexTester, everything works perfect.
Using the bash command find -regex doesn´t seem to work for me.
My question is, why?

I can’t figure it out, I am using:

find /some/path -regex ".*[\w]{4}-05(?!aid)[\w]{3}-[\w]{5}-INA\.txt" -exec echo {} \;

But nothing is printed… Any ideas?

Answer 1

bash4+ and perl

ls /some/path/**/*.txt | perl -nle 'print if /^[\w]{4}-05(?!aid)[\w]{3}-[\w]{5}-INA\.txt/'

you should have in your .profile shopt -s globstar
