colorful Christmas Tree on linux terminal

Here is a version 2 of the Christmas tree creation script. The script will create a colorful Christmas tree on the terminal. The colors of the tree will change on every run.

The script will take as input the character with which the tree has to be drawn, and any two characters that have to be used to decorated the tree.

Christmas_tree:

#!/bin/bash backslash() { b_st_row=$1 b_st_cols=$2 b_char=$3 deco=$5 b_r_end=$((b_st_row + 5 )) for((p=b_st_row;p<b_r_end;p++)) do tput setaf $4 tput cup $p $b_st_cols printf "$b_char " # sleep 1 if [ $p -eq $deco ] then temp=$((b_st_cols - 1)) tput cup $p $temp printf "$deco_char1" temp=$((temp - 2)) tput cup $p $temp printf "$deco_char2" fi ((b_st_cols++)) done echo"" } forward() { f_st_row=$1 f_st_cols=$2 f_char=$3 deco=$5 f_r_end=$((f_st_row + 5)) for((i=f_st_row;i<f_r_end;i++)) do tput cup $i $f_st_cols tput setaf $4 printf "$f_char " if [ $i -eq $deco ] then temp=$((f_st_cols + 1)) tput cup $i $temp printf "$deco_char1" temp=$((temp + 2)) tput cup $i $temp printf "$deco_char2" fi # sleep 1 ((f_st_cols--)) done echo"" } horizontal() { hrow=$2 hstart=$1 hcols=$3 char=$4 end=$((hstart + hcols)) for((i=hstart;i<=end;i++)) do # sleep 1 tput setaf $5 tput cup $hrow $i printf "$char" done echo"" } base(){ start=$1 tput setaf $4 f_st_cols=$((start - 2)) b_st_cols=$((start + 2)) rows=$2 st_row=$((rows+1)) char=$3 forward $st_row $f_st_cols "$char" $4 1000 backslash $st_row $b_st_cols "$char" $4 1000 hrow=$((st_row + 4)) hcols=12 hstart=$((start - 6)) horizontal $hstart $hrow $hcols "$char" $4 } gen_rand() { num1=$1 #num2=$((num1 + 5)) if [ $num1 -eq 0 ] then temp=$(($RANDOM % 2)) rand=$((temp + 2)) else temp=$(($RANDOM % 5)) rand=$((temp + num1)) fi } cols=`tput cols` start=$((cols/2)) echo "What character do you want to use" read char echo "Enter the first character to be used for decoration" read deco_char1 echo "Enter the second character to be used for decoration" read deco_char2 tput clear rows=5 # char="*" j=1 for((k=0;k<3;k++)) do st_row=$((k*6)) f_st_cols=$((start - k*3)) color=$RANDOM color=$((color % 6)) gen_rand $st_row forward $st_row $f_st_cols "$char" $color $rand b_st_cols=$((start + k*3)) gen_rand $st_row backslash $st_row $b_st_cols "$char" $color $rand hrow=$((j * 5 + k)) hstart=$((5+3*k)) hstart=$((start - hstart)) hcols=$((10 + k*6)) horizontal $hstart $hrow $hcols "$char" $color ((j++)) # deco $st_row $hstart $hcols done base $start $hrow "$char" $color tput setaf 4 tput cup 10 10 printf "**MERRY**" tput cup 10 90 printf "**CHRISTMAS**" tput setaf 0 end=$((hrow + 5)) tput cup $end 0

Save the script as christmas_tree.sh, give it execute permission and execute it.

$ chmod 777 christmas_tree.sh $ ./christmas_tree.sh What character do you want to use * Enter the first character to be used for decoration o Enter the second character to be used for decoration !
