Lists or filters file system objects (eg files)
f lists or filters lists of file system objects, such as files, directories, etc.
f provides a quick way to output file system items that confirm to specific criteria.
You define this criteria by using +flags (eg
+s for all symlinks) and optionally then restricting that criteria with -flags (eg
-x to remove all executable items). All flags supported as
+ are also supported as a
f will return no results. You need to include +flags.
Output is a JSON array as this format preserves whitespace in file names.
f: options -> <stdout> <stdin> -> f: options -> <stdout>
Return only directories:
Return file and directories but exclude symlinks:
f: +fd -s
Filter out files in a list (eg created by
g) using conditions set by
g: '*.go' -> f: +f rx: '\.(txt|md)' -> f: +fw
