How to get only modified files?

$ git whatchanged --since="since time" --name-only --oneline | grep -v '^.\{9\}\s' | uniq

Let's say we are in a branch called ba and we have another branch called bb. How to watch for all modified files in bb since 2 weeks ago?

$ git whatchanged  bb --since="2 weeks ago" --name-only --oneline | grep -v '^.\{9\}\s' | uniq

grep -v is used to remove lines with sha (9 chars).

How can I see branch bb modified files in a range:

$ git whatchanged  bb commitsha1..commitsha2 --name-only --oneline | grep -v '^.\{9\}\s' | sort -u

How to change line breaks to blank spaces in Unix like systems?

$ awk '{ printf "%s ", $0; } END { printf "\n"; }'

END in this case has a line break for convenience. It'll only run once, similar to if I had put a BEGIN.

How to remove more than one file using grep?

$ grep -v -e filea -e fileb -e filec

How to get modified files from a branch called bb?

$ git checkout bb -- $(git whatchanged bb commitsha1..commitsha2 --no-merges --author="snlucas" --committer="snlucas" --name-only --oneline | grep -v '^.\{9\}\s' | sort -u | awk '{ printf "%s ", $0; } END { printf "\n"; }' | tr '\n' ' ')

In this case I get all modified files using git whatchanged and used git checkout in bb branch to get these files. Also, it's important to use --, once it tells git that you're dealing with files in this part of the command, helping you avoid some headaches.

In flags --author and --committer change "snlucas" to your Git username.

Ok, I got some errors with my $ git checkout -- files

Sometimes you face some errors with some files. If it's ok, you can avoid these files:

$ git checkout bb -- $(git whatchanged bb commitsha1..commitsha2 --no-merges --author="snlucas" --committer="snlucas" --name-only --oneline | grep -v '^.\{9\}\s' | sort -u | grep -v -e errorfile1 -e errorfile2 -e errorfile3 | awk '{ printf "%s ", $0; } END { printf "\n"; }' | tr '\n' ' ')

Working with Salesforce and need help to create a package. We can use sfdx delta

$ sfdx sgd:source:delta --to commitsha2 --from commitsha1 --output manifest
