tqdm

Show progress over time of a command. More information: https://tqdm.github.io/.

• Show iterations per second and use stdout afterwards:

{{seq 10000000}} | tqdm | {{command}}

• Create a progress bar:

{{seq 10000000}} | tqdm --total {{10000000}} | {{command}}

• Create an archive out of a directory and use the file count of that directory to create a progress bar:

zip {{[-r|--recurse-paths]}} {{path/to/archive.zip}} {{path/to/directory}} | tqdm --total $(find {{path/to/directory}} | wc {{[-l|--lines]}}) --unit files --null

• Create an archive with tar and create a progress bar (system agnostic, GNU tar uses stdout while BSD tar uses stderr):

tar vzcf {{path/to/archive.tar.gz}} {{path/to/directory}} 2>&1 | tqdm --total $(find {{path/to/directory}} | wc {{[-l|--lines]}}) --unit files --null
