Type filter

pls allows the user to only list specific node types in the output.

Arguments

--typ/-t can be used to select the node types the user wants to see. The flag can be specified multiple times to enable multiple file types. Each time it can take one of these values.

Value	Description
dir	regular folder
symlink	symbolic link
fifo	named pipe
socket	file-based socket
block_device	block special device file
char_device	character special device file
file	regular file
none	shorthand: no node types
all	shorthand: all node types

Caution

Type filtering is not applicable when listing a specific node.

Mechanism

When parsing the --typ/-t flag, values are read from the CLI, in order, and added to a vector of node types till we encounter a shorthand value. If the shorthand value is none, the vector is cleared. If the shorthand value is all, the vector is filled with all the node types.

For example, consider the pls invocation below.

pls --typ=symlink --typ=all --typ=none --typ=dir

• symlink is added to the list.
• All the file types are added to the list, including the already existing symlink.
• All entries so far are dropped when none is encountered.
• dir is added to the list.

The final set contains only dir and so pls will only list the directories.

Examples

pls # or --typ=all or --t=all

​  dir/
󰌹  block_dev@ 󱞣 /dev/disk0
󰌹  char_dev@ 󰁔 /dev/null
   fifo|
   file
   socket=
󰌹  sym@ 󰁔 ./dir

 

pls --typ=dir --typ=symlink # or -t=dir -t=symlink

​  dir/
󰌹  block_dev@ 󱞣 /dev/disk0
󰌹  char_dev@ 󰁔 /dev/null
󰌹  sym@ 󰁔 ./dir

 

pls --typ=dir --typ=symlink fifo # `--typ` has no effect
