column:tldr:6e25e
This command uses the printf
and column
commands to format some text into a table.
Here's a breakdown of the command:
-
printf "header1 header2\nbar foo\n"
: This uses theprintf
command to format a string with two lines of values. The first line contains headers "header1" and "header2", separated by a space. The second line contains values "bar" and "foo", also separated by a space. The\n
represents newlines. -
|
: The vertical bar (pipe) symbol is used to connect the output of theprintf
command to the input of thecolumn
command. This is called a pipe and allows us to pass the output of one command as the input to another command. -
column --table
: This uses thecolumn
command with the--table
option to format the input data into a table. The--table
option arranges the input as a table, with appropriate spacing and alignment.
So, when the command is executed, the printf
command generates the text with headers and values, and then pipes it to the column
command, which formats it into a neat table. The output will display a two-column table with headers "header1" and "header2" and corresponding values "bar" and "foo".
