`ash` - hidden system files and globbing

[naksyl]

Recent release add support for hiding files with system attribute (ls -AA). This reminds me that globbing show files with hidden attribute wich I belive shoud be treated as Unix dotfiles (ls does not show them)

~ $ ls | grep -i ^nt

~ $ printf "%s\n" * | grep -i ^nt

The shell now has (non-standard) options to control how the hidden and system attributes affect globbing:

• nohiddenglob excludes files with the hidden attribute from globbing
• nohidsysglob excludes files with both the hidden and system attributes

Note:

• nohiddenglob takes precedence.
• The options also affect tab completion.
• The options don't affect the treatment of files that are hidden only because they start with a period. (If such files also have the hidden attribute set they are affected).

An example of the use of the new options (plus the existing nocaseglob):

~ $ set -o nocaseglob
~ $ lsattr nt*
------h-a-n NTUSER.DAT
------hsa-- NTUSER.DAT{53b39e88-18c4-11ea-a811-000d3aa4692b}.TM.blf

------hsa-- ntuser.dat.LOG2
------hs--- ntuser.ini
~ $ set -o nohidsysglob
~ $ lsattr nt*
------h-a-n NTUSER.DAT
~ $ set -o nohiddenglob
~ $ lsattr nt*
lsattr: can't stat 'nt*': No such file or directory
~ $

The options also affect tab completion.

Nice surprise.
