bash script to check if the current git branch = "x"
提问by Alexander Mills
I am very bad at shell scripting (with bash), I am looking for a way to check if the current git branch is "x", and abort the script if it is not "x".
我在 shell 脚本（使用 bash）方面非常糟糕，我正在寻找一种方法来检查当前的 git 分支是否为“x”，如果它不是“x”，则中止脚本。
#!/usr/bin/env bash
CURRENT_BRANCH="$(git branch)"
if [[ "$CURRENT_BRANCH" -ne "master" ]]; then
echo "Aborting script because you are not on the master branch."
return; # I need to abort here!
fi
echo "foo"
but this is not quite right
但这并不完全正确

Use git rev-parse --abbrev-ref HEADto get the name of the current branch.
使用git rev-parse --abbrev-ref HEAD来获得当前分支的名字。
Then it's only a matter of simply comparing values in your script:
那么这只是简单地比较脚本中的值的问题：
BRANCH=$(git rev-parse --abbrev-ref HEAD)
if [[ "$BRANCH" != "x" ]]; then
echo 'Aborting script';
exit 1;
fi
echo 'Do stuff';

One option would be to parse the output of the git branchcommand:
一种选择是解析git branch命令的输出：
BRANCH=$(git branch | sed -nr 's/\*\s(.*)//p')
if [ -z $BRANCH ] || [ $BRANCH != "master" ]; then
exit 1
fi
But a variant that uses git internal commands to get just the active branch name as suggested by @knittl is less error prone and preferable
但是使用 git 内部命令仅获取@knittl 建议的活动分支名称的变体更不容易出错且更可取

You want to use exitinstead of return.
您想使用exit而不是return.
