In a bash script, you can get the current branch's name programmatically thus:
#!/bin/bash
branch_name=$(git symbolic-ref -q HEAD)
echo $branch_name
branch_name=${branch_name##refs/heads/}
echo $branch_name
branch_name=${branch_name:-HEAD}
echo $branch_nameBeware, to find a branch name (whether checked out or not) according to a pattern:
#!/bin/bash
git checkout production.release.4.2
production_branch=`git branch | grep "production"`
# May not give the expected result:
# the character $ is being treated as a wildcard and will be expanded, so that the output may include all files in the directory:
echo $production_branch
# Using double quotes solve the problem:
echo "$production_branch"Issues related to this page:
