string-pad - pad strings to a fixed width

=========================================

Synopsis
|
|
--------
|
|
|
|
.. BEGIN SYNOPSIS
|
|
|
|
::
|
|
|
|
string pad [(-r | --right)] [(-c | --char) CHAR] [(-w | --width) INTEGER] [STRING...]
|
|
|
|
.. END SYNOPSIS
|
|
|
|
Description
|
|
-----------
|
|
|
|
.. BEGIN DESCRIPTION
|
|
|
|
``string pad`` extends each STRING to the given visible width by adding CHAR to the left. That means the width of all visible characters added together, excluding escape sequences and accounting for $fish_emoji_width and $fish_ambiguous_width. It is the amount of columns in a terminal the STRING occupies.
|
|
|
|
The escape sequences reflect what *fish* knows about, and how it computes its output. Your terminal might support more escapes, or not support escape sequences that fish knows about.
|
|
|
|
If ``-r`` or ``--right`` is given, add the padding after a string.
|
|
|
|
If ``-c`` or ``--char`` is given, pad with CHAR instead of whitespace.
|
|
|
|
The output is padded to the maximum width of all input strings. If ``-w`` or ``--width`` is given, use at least that.

Examples

.. BEGIN EXAMPLES
|

abc
|
|
abcdef
|
|
|
|
>_ string pad --right --char=🐟 "fish are pretty" "rich. "
|
|
fish are pretty
|
|
rich. 🐟🐟🐟🐟
|
|
|
|
>_ string pad -w$COLUMNS (date)
|

|
- The :ref:`printf <cmd-printf>` command can do simple padding, for example ``printf %10s\n`` works like ``string pad -w10``.
|
|
|
|
- :ref:`string length <cmd-string-length>` with the ``--visible`` option can be used to show what fish thinks the width is.
