What is core.autocrlf and core.safecrlf?

Question

git

Please explain the purpose of these commands below with different options. How do they work?
core.autocrlf true (false, inline)
core.safecrlf true (false, warn)

Answer 1

Setting core.autocrlf with "true" and "input" makes all line translations of text files in the main repository the same.
core.autocrlf true - git automatically converts CRLF->LF on commit and back to LF->CRLF when checking out code from the repository to the file system (used on Windows).
core.autocrlf input - convert CRLF to LF on commits only (used on Mac/Linux).
If core.safecrlf is set to "true" or "warm", Git checks if the transformation is reversible for the current core.autocrlf setting.
core.safecrlf true - rejects irreversible lf<->crlf conversion. Useful when specific binaries look like text files.
core.safecrlf warn - Print only a warning, but accept an irreversible transition.
