# 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`
