I was just wondering how you would echo out different length variables but still have them all line up. I tried putting tabs between the variables but that didn't work as planned.
For example this is in some loop, with different variables in it each time:
echo "$1 $2 $3 $4 $5"

Hi...I am trying to make a script like this:
mmc=123
echo "$mmc" > 123.txt
The variable "mmc" has to be declared right on the beginning of the script, so when I open 123.txt, I get:

wordwrap
WORDWRAP(3) 1 WORDWRAP(3)wordwrap - Wraps a string to a given number of charactersSYNOPSIS
string wordwrap (string $str, [int $width = 75], [string $break = "0], [bool $cut = false])
DESCRIPTION
Wraps a string to a given number of characters using a string break character.
PARAMETERS
o $str
- The input string.
o $width
- The number of characters at which the string will be wrapped.
o $break
- The line is broken using the optional $break parameter.
o $cut
- If the $cut is set to TRUE, the string is always wrapped at or before the specified $width. So if you have a word that is larger
than the given width, it is broken apart. (See second example). When FALSE the function does not split the word even if the $width
is smaller than the word width.
RETURN VALUES
Returns the given string wrapped at the specified length.
