Even More Useful Linux Examples
Continuing my series on “Useful-Linux-Examples”, yet another eclectic collection of useful things in Linux
Run commands for every line in a file (with parallelism)
Example running du -s
for each line
parallel -a list-of-file-paths.txt -k du -s {}
Important flags:
-a
reading from the file, line by line-k
preserves order
Monitor the progress of a file lines being generated
watch wc -l my-updating-file.txt
Important flags:
-n
interval in seconds-d
highlight difference
Git
A safer version of git push -f
/ git push --force
git push --force-with-lease
Add a template repo as a remote to continue to pull updates with their commit messages
git remote add template [template repo]
git fetch --all
git merge template/[branch name] --allow-unrelated-histories
Alternatively, if the template repo is a cookiecutter repo, the following might be better
Get new updates from cookiecutter repo
Check out cruft
Even if the repo was originally started from vanilla cookiecutter, cruft can take over with just the commit of the template repo
