- 程序一:
- 彩色显示文件程序,每个字符的颜色都不一样,随机变化,让你看花眼睛^_^:
- 程序代码:
- #! /usr/bin/awk
- # Write by dbcat
- # EMail:[email protected]
- # run : awk -f ColorCat.awk YourFile
- BEGIN{
- srand()
- }
- {
- split($0,Myth,"")
- ColorPrint(Myth,length($0))
- }
- function ColorPrint(Myth,xlen)
- {
- for(i=1;i<=xlen;i++)
- {
- Color="\033[1;"int(31+7*rand())
- printf "%s;3m%s\033[0m",Color,Myth[i]
- }
- printf "\n"
- }
- 程序二:
- 彩色作图程序,有点像Gnuplot,可以作出圆形,正弦图,抛物线等等。
- 例如:
- 圆: awk 'BEGIN{while(k<10){print sin(k),cos(k);k=k+0.01}}' | awk -f ColorPlot.awk
- 正弦线: awk 'BEGIN{while(k<10){print sin(k),k;k=k+0.01}}' | awk -f ColorPlot.awk
- 抛物线: awk 'BEGIN{k=-10;while(k<10){print k^2,k;k=k+0.01}}' | awk -f ColorPlot.awk
- 直线: paste <(seq 1 0.01 10) <(seq 1 0.01 10) | awk -f ColorPlot.awk
- 如果你有想象力的话还可以作出很多意想不到的图形,比如:
- 圆盘: awk 'BEGIN{while(k<100){print sin(k),rand()*cos(k);k=k+0.01}}' |awk -f ColorPlot.awk
- 花圈: awk 'BEGIN{srand()
- while(k++<20000){
- x=2-3*rand()
- y=2-4*rand()
- if(x^2+y^2>0.6&&x^2+y^2<1||x^2+y^2<0.3&&x^2+y^2>0.1)
- print x,y
- }
- }' | awk -f ColorPlot.awk
- 菱圈: awk 'BEGIN{srand()
- while(k++<20000){
- x=1-2*rand()
- y=1-2*rand()
- if(x+y<=1&&x-y<=1&&-x+y<=1&&-x-y<=1&&x^2+y^2>=1/2)
- print x,y
- }
- }' | awk -f ColorPlot.awk

- for(i=1;i<=Len;i++)
- {
- X_Label[i]=int((X_Label[i]-X_Min)/(X_Max-X_Min)*(xlen-1) + 1)
- Y_Label[i]=int((Y_Label[i]-Y_Min)/(Y_Max-Y_Min)*(ylen-1) + 1)
- Myth[X_Label[i],Y_Label[i]]=int(40+60*rand())
- }
- }
- function PrintGraph(Myth,i,j)
- {
- for(i=1;i<=xlen;i++)
- {
- for(j=1;j<=ylen;j++)
- {
- color="\033[1;"int(31+7*rand())
- printf " %s;1m%c\033[0m",color,Myth[i,j]
- }
- printf "\n"
- }
