It acts as a temporary storage location for the <a href=\"..\/SHA-1\/\">SHA-1<\/a> hashes of the branch tips retrieved from the remote server.<\/p><p>When a developer performs a <a href=\"..\/GIT-PULL\/\">GIT-PULL<\/a>, Git internally executes a fetch and records the results in this file. The first entry in <code>FETCH_HEAD<\/code> is typically the branch that was intended to be merged into the current <a href=\"..\/HEAD-REFERENCE\/\">HEAD-REFERENCE<\/a>. This mechanism allows the subsequent <a href=\"..\/GIT-MERGE\/\">GIT-MERGE<\/a> or <a href=\"..\/GIT-REBASE\/\">GIT-REBASE<\/a> to proceed even if the remote tracking branches have not been explicitly updated in the local <a href=\"..\/GIT-REFS\/\">GIT-REFS<\/a> hierarchy.<\/p><p>Detailed technical specifications regarding the format of this file can be found in the <a href=\"https:\/\/git-scm.com\/book\/en\/v2\/Git-Internals-Git-References\">Git Internals documentation<\/a>. It contains the commit ID, a merge status flag, and the source identity. This file is crucial for <a href=\"..\/GIT-PLUMBING\/\">GIT-PLUMBING<\/a> commands that require direct access to the latest fetched data without traversing the entire object database.<\/p><ul><li><a href=\"..\/GIT-REFS\/\">GIT-REFS<\/a><\/li><li><a href=\"..\/GIT-REMOTE\/\">GIT-REMOTE<\/a><\/li><li><a href=\"..\/HEAD-REFERENCE\/\">HEAD-REFERENCE<\/a><\/li><li><a href=\"..\/GIT-PLUMBING\/\">GIT-PLUMBING<\/a><\/li><\/ul>",
