Fancy progress bar for terminal

pbar : Fancy progress bar for TUI/CLI

Usage

pbar [-b <character_block>] [-c <0-7>] [-t <title>] [-s <total_size>] [<input_file>]

Options

-b passed which block to repeat. Must contain only one printable character. Default: Full block

-c pass a number from 0 to 7 denoting the color of the progress bar. 0=Black; 1=Red; 2=Green; 3=Yellow; 4=Blue; 5=Cyan; 6=Magenta; 7=White. Default: 2

-t pass title to display

-s pass the maximum that the input numbers would reach; i.e. the value at which progress would be 100%. Default: 100

Input

Either provide an input file (normal file or pipe) as argument or input is read from stdin. Input file, if any, is deleted by pbar on exit. Input is given in the format:

index status

index status

..

index status

final display string

Index is a number whose ratio with the total_size or maximum determines the progress percentage.

Status is any inline string (containing no new line character) to be displayed below the progress bar at the given percentage.

The final display string is a string to be displayed after progress is complete.

Example

1. Pipe based

for i in $(seq 1 10);do
  echo "$i Step: $i"
  ((i!=10)) && sleep 1 || echo Done
done | pbar -s 10 -c 4 -t "Progress Bar"

2. Command substitution based

pbar -s 5 <(for i in `seq 1 5`; do echo $i; sleep 1; done)

3. File based. The file is deleted by pbar at the end.

pbar -b '#' /tmp/input &
{ for i in `seq 1 100`; do echo $i; sleep 0.05; done; echo Done;} > /tmp/input
