Several groups of Shell-written progress bar programs

1. Add the $ symbol:
#! /Bin/sh
Echo | awk '{printf "^) ^", $1 }'
While sleep 1
Do
Echo "$" | awk '{printf "% s", $1 }'
Done

 

2 changed sticks:
#! /Bin/bash

I = 0
While [$ I-lt 10]
Do
For J in '-''//'' | ''/'
Do
Echo-ne "/033 [1D $ J"
Usleep 50000
Done
(I ++ ))
Done

 

3. display the progress bar:
#! /Bin/bash

I = 0
While [$ I-lt 20]
Do
(I ++ ))
Echo-ne "=>/033 [s"
Echo-ne "/033 [40; 50 H" $ (I x 5*100/100) % "/033 [U/033 [1D"
Usleep 50000
Done
Echo

 

4. display the progress bar and changed table names:
#! /Bin/bash

I = 0
Total = 53

percent = $ (echo "scale = 4; 100/$ total" | BC)
while [$ I-lt $ total]
DO
(I ++)
H = $ (echo "scale = 1; $ percent * $ I "| BC)
H = $ (echo" $ H + 0.5 "| BC | cut-D. -F1)
echo-ne "/033 [40; 1 hcopy table: T $ I ($ I/$ total) $ H %/033 [U/033 [1D "
usleep 50000
done
echo
