Perc2

/bin/perc2

An attempt to do a script that would show percentage bar with 1/8 of single char resolution, using some unicode block chars

#U+2588	█	Full block                  100  %
#U+2589	▉	Left seven eighths block    87.5 %
#U+258A	▊	Left three quarters block   75   %
#U+258B	▋	Left five eighths block     62.5 %  
#U+258C	▌	Left half block             50   %
#U+258D	▍	Left three eighths block    37.5 %
#U+258E	▎	Left one quarter block      25   %
#U+258F	▏	Left one eighth block       12.5 %

For a usage and tests see the beginning of the script.

Example output

for i in $(seq 0 0.1 100) ; do echo -ne "$i\t"; perc2 $i 100; done
27.0	███████████████████████████
27.1	███████████████████████████▏

27.6	███████████████████████████▋
27.7	███████████████████████████▊

Usage examples

perc2 90 10 
# int or float, int

should give 90 percent over the range of 10 chars (10 chars is 100%).

perc2 10

should give 10 percent over the range of terminal width (tput cols).

Enabling info (info=”1”) in script should give you some basic debug info, like so

perc2 12
█████████████████▋full=17 perc=62.5 asci=▋

where full is fullchars, perc is last block in percentage and asci is the closest representation of that percentage.
