get subfolders under a folder named with uppercases only-CodePudding

I want to get the list of subfolders with names in uppercase only (folder name only, without leading pardir or tailing /).

I tried find . -maxdepth 1 -type d -name '[A-Z] ' but it doesn't work.

CodePudding user response：

If you want upper-case names in Regex, use the [:upper:] class name:

find . -maxdepth 1 -type d -regextype posix-extended -regex './[[:upper:]] '

Or using Bash's extglob Extended Globbing:

shopt -s extglob
printf %s\\n  ([[:upper:]])/

CodePudding user response：

The -name operator does not use regular expressions as you might expect. Instead it using "wildcards" similar to the bash wildcard system as described here.

You probably want to use the -regex operator as described in the Full Name Patterns section of the documentation. Using this you should have a command like:

find . -maxdepth 1 -regex '\./[A-Z] '

You can do any other path operations using the options described in the Run Commands section.
