gdu:tldr:a8201
The command you provided is using the gdu
command with the --ignore-dirs-pattern
option and the argument '${-*[abc]+}'
.
gdu
is a tool used for disk usage analysis, similar to the du
command. It displays summarized and sorted information about the disk space usage in a directory tree.
The --ignore-dirs-pattern
option allows you to specify a regular expression pattern that matches directory names to be ignored during the disk usage analysis. In this case, the pattern is '${-*[abc]+}'
.
The pattern '${-*[abc]+}'
is a regular expression that matches directories whose names contain any combination of letters 'a', 'b', and 'c'. The *
indicates that there can be zero or more characters before and after the pattern.
When this command is executed, it will perform a disk usage analysis using gdu
, excluding directories whose names match the given regular expression pattern.
