Examples

Demo

Simple use: # lines or seconds is known

# when the approx number of lines output is known
# e.g. first do a rsync --dry-run to check how many files have to be trasferred
# and then use this number in the actual operation
$ expected_lines=$(rsync --dry-run <from> <to> | awk 'END {print NR}')
$ rsync <from> <to> | progressbar lines "$expected_lines"

# similarly: when the approx number of seconds is known
$ <do_something_for_1_hour> | progressbar seconds 3600

Auto-estimate lines/seconds

# the first time the script learns the expected # lines/seconds for operation '40-pings-to-google'
$ ping -c 40 www.google.com | progressbar lines 40-pings-to-google
45 lines / 39 secs …

# the following times, it can use this information to show a 0-100% progressbar
$ ping -c 40 www.google.com | progressbar lines 40-pings-to-google
[############################--3---------4---------5---------6---------7---------8---------9--------] 28% / 11 secs … 

# can also be used with different progress bar format (here: short)
$ ping -c 40 www.google.com | progressbar -b short lines 40-pings-to-google
[##-------] 28% / 11 secs … 

# use '|' as character for 'done' time
$ ping -c 40 www.google.com | progressbar -c '|' lines 40-pings-to-google
[|||||||||||||||||||||||||||||||||||-----4---------5---------6---------7---------8---------9--------] 35% / 14 secs … 


# for instance, to use it with rsync, first do a --dry-run (rather fast) to get the estimated # of lines
$ rsync --dry-run -avz source/ destination/ | progressbar lines long-rsync-operation

# and then run the actual operation, which will take much longer, but will output +- the same # of lines
$ rsync -avz source/ destination/ | progressbar lines long-rsync-operation
