Creating animated 2018 on the terminal

In the post "Creating 2018 on the terminal" we created 2018 on the terminal. Here is a small extension to the same, to make it appear on character at a time giving it the effect of an animation.

#!/bin/bash #create 2017 on terminal using any user specified character str_dwn() { rows=$1 s_start=$2 char=$4 str_st_row=$3 rows_end=$((str_st_row+rows)) for((i=str_st_row;i<rows_end;i++)) do tput cup $i $s_start printf "$char " done echo"" } backslash() { b_st_row=$1 b_st_cols=$2 b_char=$3 b_r_end=$((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 " ((b_st_cols++)) done echo"" } forward() { f_st_row=$1 f_st_cols=$2 f_len=$3 f_char=$4 f_r_end=$((f_st_row + $f_len)) for((i=f_st_row;i<f_r_end;i++)) do tput cup $i $f_st_cols printf "$f_char " ((f_st_cols--)) done echo"" } horizontal() { hrow=$2 hstart=$1 hcols=$3 char=$4 end=$((hstart + hcols)) for((i=hstart;i<=end;i++)) do tput cup $hrow $i printf "$char" done echo"" } gen_rand() { num1=$1 if [ $num1 -eq 0 ] then temp=$(($RANDOM % 2)) rand=$((temp + 2)) else temp=$(($RANDOM % 5)) rand=$((temp + num1)) fi } two() { hstart_2=$1 hrow_be=$2 hcols_2=$3 char=$4 color=$5 set_color horizontal $hstart_2 $hrow_be $hcols_2 "$char" st_row_2=$((hrow_be+1)) f_st_cols_2=$((hstart_2+hcols_2)) forward $st_row_2 $f_st_cols_2 5 "$char" $color hstart_2_lo=$start hrow_2_lo=$((hrow_be+6)) hcols_2_lo=5 horizontal $hstart_2_lo $hrow_2_lo $hcols_2_lo "$char" } zero() { set_color hstart_0=$((f_st_cols_2 +4)) hcols_0=5 horizontal $hstart_0 $hrow_be $hcols_0 "$char" str_dwn_col_0=$hstart_0 str_dwn_row_0=$((hrow_be + 1)) str_dwn 6 $str_dwn_col_0 $str_dwn_row_0 "$char" hstart_0_lo=$((f_st_cols_2 +4)) hcols_0_lo=6 hrow_0_lo=$((hrow_be+6)) horizontal $hstart_0 $hrow_0_lo $hcols_0 "$char" str_dwn_col_rig_0=$((hstart_0 +5)) str_dwn_row_rig_0=$((hrow_be + 1)) str_dwn 6 $str_dwn_col_rig_0 $str_dwn_row_rig_0 "$char" } one() { set_color str_dwn_col_1=$((str_dwn_col_rig_0 + 4)) str_dwn_row_1=$((hrow_be)) str_dwn 7 $str_dwn_col_1 $str_dwn_row_1 "$char" } eight() { set_color set_color hstart_8=$((str_dwn_col_1 +4)) hcols_8=5 horizontal $hstart_8 $hrow_be $hcols_8 "$char" str_dwn_col_8=$hstart_8 str_dwn_row_8=$((hrow_be + 1)) str_dwn 6 $str_dwn_col_8 $str_dwn_row_8 "$char" hstart_8_lo=$((f_st_cols_2 +4)) hcols_8_lo=6 hrow_8_lo=$((hrow_be+6)) horizontal $hstart_8 $hrow_8_lo $hcols_8 "$char" str_dwn_col_rig_8=$((hstart_8 +5)) str_dwn_row_rig_8=$((hrow_be + 1)) str_dwn 6 $str_dwn_col_rig_8 $str_dwn_row_rig_8 "$char" hstart_8_lo=$((f_st_cols_2 +4)) hcols_8_lo=6 hrow_8_lo=$((hrow_be+3)) horizontal $hstart_8 $hrow_8_lo $hcols_8 "$char" } set_color(){ color=$RANDOM color=$((color%6)) tput setaf $color } cols=`tput cols` mid=$((cols/2)) start=$((mid-16)) echo "What character do you want to use" read char tput clear rows=5 begin_row=2 num_cols=6 two $start $begin_row $num_cols "$char" $color; sleep 2 zero sleep 2 one sleep 2 eight sleep 2 ; tput setaf 7 tput cup 9 0

Save the script as animated_2017.sh and run it in the terminal

bash animated_2017.sh

You should see 2017 appear one character at a time on the terminal.

Creating 2018 on the terminal

Here is a bash script which can be used to create the text 2018 on the terminal using any characher of your choice.

#!/bin/bash #create 2017 on terminal using any user specified character str_dwn() { rows=$1 s_start=$2 char=$4 str_st_row=$3 rows_end=$((str_st_row+rows)) for((i=str_st_row;i<rows_end;i++)) do tput cup $i $s_start printf "$char " done echo"" } backslash() { b_st_row=$1 b_st_cols=$2 b_char=$3 b_r_end=$((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 " ((b_st_cols++)) done echo"" } forward() { f_st_row=$1 f_st_cols=$2 f_len=$3 f_char=$4 f_r_end=$((f_st_row + $f_len)) for((i=f_st_row;i<f_r_end;i++)) do tput cup $i $f_st_cols printf "$f_char " ((f_st_cols--)) done echo"" } horizontal() { hrow=$2 hstart=$1 hcols=$3 char=$4 end=$((hstart + hcols)) for((i=hstart;i<=end;i++)) do tput cup $hrow $i printf "$char" done echo"" } gen_rand() { num1=$1 if [ $num1 -eq 0 ] then temp=$(($RANDOM % 2)) rand=$((temp + 2)) else temp=$(($RANDOM % 5)) rand=$((temp + num1)) fi } two() { hstart_2=$1 hrow_be=$2 hcols_2=$3 char=$4 color=$5 set_color horizontal $hstart_2 $hrow_be $hcols_2 "$char" st_row_2=$((hrow_be+1)) f_st_cols_2=$((hstart_2+hcols_2)) forward $st_row_2 $f_st_cols_2 5 "$char" $color hstart_2_lo=$start hrow_2_lo=$((hrow_be+6)) hcols_2_lo=5 horizontal $hstart_2_lo $hrow_2_lo $hcols_2_lo "$char" } zero() { set_color hstart_0=$((f_st_cols_2 +4)) hcols_0=5 horizontal $hstart_0 $hrow_be $hcols_0 "$char" str_dwn_col_0=$hstart_0 str_dwn_row_0=$((hrow_be + 1)) str_dwn 6 $str_dwn_col_0 $str_dwn_row_0 "$char" hstart_0_lo=$((f_st_cols_2 +4)) hcols_0_lo=6 hrow_0_lo=$((hrow_be+6)) horizontal $hstart_0 $hrow_0_lo $hcols_0 "$char" str_dwn_col_rig_0=$((hstart_0 +5)) str_dwn_row_rig_0=$((hrow_be + 1)) str_dwn 6 $str_dwn_col_rig_0 $str_dwn_row_rig_0 "$char" } one() { set_color str_dwn_col_1=$((str_dwn_col_rig_0 + 4)) str_dwn_row_1=$((hrow_be)) str_dwn 7 $str_dwn_col_1 $str_dwn_row_1 "$char" } eight() { set_color set_color hstart_8=$((str_dwn_col_1 +4)) hcols_8=5 horizontal $hstart_8 $hrow_be $hcols_8 "$char" str_dwn_col_8=$hstart_8 str_dwn_row_8=$((hrow_be + 1)) str_dwn 6 $str_dwn_col_8 $str_dwn_row_8 "$char" hstart_8_lo=$((f_st_cols_2 +4)) hcols_8_lo=6 hrow_8_lo=$((hrow_be+6)) horizontal $hstart_8 $hrow_8_lo $hcols_8 "$char" str_dwn_col_rig_8=$((hstart_8 +5)) str_dwn_row_rig_8=$((hrow_be + 1)) str_dwn 6 $str_dwn_col_rig_8 $str_dwn_row_rig_8 "$char" hstart_8_lo=$((f_st_cols_2 +4)) hcols_8_lo=6 hrow_8_lo=$((hrow_be+3)) horizontal $hstart_8 $hrow_8_lo $hcols_8 "$char" } set_color(){ color=$RANDOM color=$((color%6)) tput setaf $color } cols=`tput cols` mid=$((cols/2)) start=$((mid-16)) echo "What character do you want to use" read char tput clear rows=5 begin_row=2 num_cols=6 two $start $begin_row $num_cols "$char" $color;zero;one;eight tput setaf 7 tput cup 9 0

We have entered "&" as the character, and you should see the output as shown below.

There was error copying file to media... error splicing file.

While copying a large file into a pen drive or any other external storage system if you get the error

There was error copying file to media... error splicing file.

As shown in the image below.



The error is because FAT filesystem does not seem to support copying files which are too large. So to work around this problem you will have to make the pen drive into a NTFS file system. Which can be done easily using the command mkfs.ntfs

Connect the pendrive and find out the partition number using the command

sudo fdsik -l



From the list of partitions, note the partition number of the pen drive that has to be converted to NTFS. Be very careful cause of you use the wrong partition you will loose all the data in it. Let us assume the partition is /dev/sdb1

unmount the partition using umount

sudo umount /dev/sdb1

Now to convert it to ntfs

sudo mkfs.ntfs /dev/sdb1

Creating NTFS partition might take some time depending on the size of the disk. Once the formatting is done, any file size can be copied into it.
