STRING-PAD(1)

NAME
string-pad - pad strings to a fixed width

SYNOPSIS
string pad [-r | --right] [(-c | --char) CHAR] [(-w | --width) INTEGER]
           [STRING ...]

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

>_ string pad -w 10 abc abcdef
       abc
    abcdef
>_ string pad --right --char=🐟 "fish are pretty" "rich. "
fish are pretty
rich.  🐟🐟🐟🐟
>_ string pad -w$COLUMNS (date)
# Prints the current time on the right edge of the screen.

SEE ALSO

•   The printf command can do simple padding, for example printf %10s\n works like string pad -w10.

•   string length with the --visible option can be used to show what fish thinks the width is.
