 # tqdm
 
-> Create a progress bar.
+> 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 --null`
+`{{seq 10000000}} | tqdm --total 10000000 | {{command}}`
-`{{seq 10000000}} | tqdm --total 10000000 | {{command}}`
+`{{seq 10000000}} | tqdm --total {{10000000}} | {{command}}`
-`{{seq 10000000}} | tqdm --total 10000000 | {{command}}`
+`{{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 {{backup.zip}} {{dir}} | tqdm --total $(find {{dir}} | wc -l) --unit files --null`
-`zip -r {{backup.zip}} {{dir}} | tqdm --total $(find {{dir}} | wc -l) --unit files --null`
+`zip -r {{path/to/archive.zip}} {{path/to/directory}} | tqdm --total $(find {{path/to/directory}} | wc -l) --unit files --null`
-`zip -r {{backup.zip}} {{dir}} | tqdm --total $(find {{dir}} | wc -l) --unit files --null`
+`zip -r {{backup.zip}} {{dir}} | tqdm --total $(find {{dir}} | wc -l) --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) --unit files --null`
-`zip -r {{backup.zip}} {{dir}} | tqdm --total $(find {{dir}} | wc -l) --unit files --null`
+`zip -r {{backup.zip}} {{dir}} | tqdm --total $(find {{dir}} | wc -l) --unit files --null`
