Merry Xmas & Happy New Year rel.2

Last year I prepared a virtual tree for the dba, so now it’s time to replicate this year for the systems engineers with best wishes for a merry Xmas and happy new year.

bash

[ecairo@localhost ~]$ cat ./tree.sh
#!/bin/bash

RED='\033[0;31m'
GREEN='\033[0;32m'
YELLOW='\033[1;33m'
NOCOLOR='\033[0m'
ROWS=11
COLUMNS=21

blanks() {
    for ((k=0; k<${1}; k++)) ; do
        printf " "
    done
}

printf "\n"; blanks $(((COLUMNS-1)/2)); printf "${YELLOW}X\v\b|\n"

for (( i=1; i <= ${ROWS}; i++ )); do
    BLANKS=$(( ( ( (COLUMNS-1) * (i-1) / (ROWS-1) + 1 ) / 2 ) * 2 + 1 ))
    blanks $(( (COLUMNS-BLANKS) / 2 ))

    for ((j=0; j<${BLANKS}; j++)) ; do
        printf "${GREEN}*"
    done

    printf "\n"
done

blanks $(( (COLUMNS-3)  / 2 )); printf "${RED}mMm\n"
blanks $(( (COLUMNS-3)  / 2 )); printf "${RED}mMm\n\n"
blanks $(( (COLUMNS-8)  / 2 )); printf "${YELLOW}Marry Xmas\n"
blanks $(( (COLUMNS-16) / 2 )); printf "${YELLOW}and Happy New $(( $(date +'%Y') + 1 ))\n\n${NOCOLOR}"

Here you are the result (of course it’s better with a dark background).

[ecairo@localhost ~]$ ./tree.sh

          X
          |
          *
         ***
        *****

      Marry Xmas
  and Happy New 2019
