git-check-ref-format - Linux
Overview
git-check-ref-format
verifies whether a given string matches the correct format for a reference name in Git. It’s useful for validating reference names in scripts or ensuring that references follow Git’s naming conventions.
Syntax
git check-ref-format <refname>
Options/Flags
None.
Examples
Verifying a Simple Reference Name:
git check-ref-format master
Validating a Reference Name with Special Characters:
git check-ref-format refs/tags/v1.0.0-rc1
Common Issues
- Invalid Characters: Reference names must not contain
/
,*
,?
,[
,]
, or^
. - ** Leading and Trailing Slashes:** Reference names cannot start or end with a
/
. - Case Sensitivity: Git treats reference names as case-insensitive, so
refs/heads/main
andrefs/heads/Main
are considered the same.
Integration
git-check-ref-format
can be used with other commands to validate reference names before performing operations:
# Create a new branch if the reference name is valid
if git check-ref-format $new_branch; then
git branch $new_branch
else
echo "Invalid branch name: $new_branch"
fi
