column:tldr:d0efe
This command is used to format and display tabular data in a table-like structure in the terminal.
Here is the breakdown:
-
printf "header1,header2\nbar,foo\n"
: This command prints the specified text. In this case, it is printing the headers 'header1' and 'header2', followed by a line break (\n
), and then the values 'bar' and 'foo', again followed by a line break. This acts as the data to be formatted and displayed. -
|
: The pipe symbol (|
) is used to redirect the output of the preceding command (printf
) and pass it as input to the next command (column
). -
column
: This command is used to format the input into a table-like structure. By default, it aligns the columns by adjusting the spacing. -
--table
: This option is used to specify that the input should be formatted as a table. -
--separator ${,}
: This option sets the separator used between columns to be a comma (,
). The${,}
is shell syntax to expand the value of the,
variable, which is set to a comma.
In summary, the command takes the specified data, formats it as a table, and separates the columns using a comma as the separator. The resulting table is then displayed in the terminal.
