javascript - What's the difference between dir/* , dir/**, dir/**/* , dir/**/*.* in globbing? -



javascript - What's the difference between dir/* , dir/**, dir/**/* , dir/**/*.* in globbing? -

imagine next directory structure:

web/ sub1/ 1.js 3.js

when utilize 'del' node module delete file or directory, behavior of dir/* , dir/**, dir/**/*, dir/**/*.* different.

web/*

del(['web/*', '!web/sub1/1.js']) -> under web/ removed, web/sub1/1.js removed well del(['web/*', '!web/3.js']}) -> under web/ removed except 3.js keeped

web/**

del(['web/**', '!web/sub1/1.js']), del(['web/**', '!web/3.js']) -> result of 2 forms same, web/ removed

web/**/*

del(['web/**/*', '!web/sub1/1.js']) -> under web/ removed del(['web/**/*', '!web/3.js']}) -> under web/ removed except 3.js keeped

web/**/*.*

del(['web/**/*.*', '!web/sub1/1.js']) -> files under web/ removed except web/sub/1.js , directory construction keeped del(['web/**/*.*', '!web/3.js']}) -> files under web/ removed except 3.js , directory construction keeped

after done above test, i'm totally confused, can't summarize rule out of above test. , can't find detailed documentation explaining these. can help here??

node del uses node-glob matching targets , rimraf removing matched targets. matched targets passed rimraf , rimraf remove file or remove directory recursively. reply question targets matched patterns.

web/*

all kid items matched: web/sub1, web/3.js. removed, !web/sub1/1.js not exclude anything. !web/3.js excludes file, web/sub1 removed recursively.

web/**

the directory , nested items matched: web, web/sub1, web/sub1/1.js, web/3.js. because directory removed recursively files exclusions not efficient.

web/**/*

all nested items matched: web/sub1, web/sub1/1.js, web/3.js. web/sub1 removed recursively , exclusion !web/sub1/1.js not matter. exclusion !web/3.js keeps file.

web/**/*.*

only nested files matched: web/sub1/1.js, web/3.js. no directories removed , exclusion of file keeps it.
