cut:tldr:8f400
This command combines the use of two commands in a Unix-like operating system:
-
${command}
: This is a placeholder for a specific command that will be used as input for the next command in the pipeline. It can be any valid command or program that produces output. -
|
(pipe operator): This symbol is used to redirect the output of the previous command as input to the next command. In this case, the output of${command}
will be passed as input to thecut
command. -
cut
command: This is a command-line tool used to extract specific columns or fields from a file or input stream. It allows you to specify a delimiter and select certain columns to extract. -
-${select}
: This parameter determines the delimiter used by thecut
command. It specifies the character or field position to use as the delimiter for cutting. -
${select1}
: This parameter specifies the field or column to extract from the input usingcut
. It can be a single field number, a range, or a comma-separated list of field numbers.
So, overall, this command is used to take the output of ${command}
, set the delimiter with -
, and then extract the desired field or column using ${select1}
. This can be useful for data manipulation and filtering.
