I would create a function for that

How would this function work exactly?

Well something like this to give you an idea:
Code:
RED="\e[0;31m"
BLUE="\e[0;34m"
GREEN="\e[0;32m"
NOCOLOR="\e[0m"

formatprint() {
  printf "${3}%${2}s\n${NOCOLOR}" "$1"
}

formatprint "Hello World"
formatprint "Hello World" 16
formatprint "Hello World" 24
formatprint "Hello World" 30 "$RED"
formatprint "Hello World" 36 "$GREEN"

If you are using bash 4 or ksh93 (my favorite for shell scripts) you can use associative array elements for the colors instead of variables

Thank you for this. Associative arrays are very nice, but cannot use them when running my scripts on some clusters I have available, which is a pity.

As an addition, I am constructing some mnemonic keywords from which I can quickly extract information. I use three attributes: s, v, and d.

Mnemonic examples:
Code:
1s             one option
2s             two options
3s             three options
1sv           one option with value
1s2v         one option with two values
2sv           two options with value
2svd         two options with value and description

I want to determine the total number of attributes in the string as follows:
Code:
1s              nAtrb=1
2s              nAtrb=2
3s              nAtrb=3
1sv            nAtrb=2
1s2v          nAtrb=3
2sv            nAtrb=3
2svd          nAtrb=4
