Question

我需要将分支名称中的任务代码添加到每个提交中。我们发现这应该通过钩子完成。

代码如下：

#!/bin/bash
# Include any branches for which you wish to disable this script
if [ -z "$BRANCHES_TO_SKIP" ]; then
BRANCHES_TO_SKIP=(master develop)
fi
# Get the current branch name and check if it is excluded
BRANCH_NAME=$(git symbolic-ref --short HEAD)
BRANCH_EXCLUDED=$(printf "%s\n" "${BRANCHES_TO_SKIP[@]}" | grep -c "^$BRANCH_NAME$")
# Trim it down to get the parts we're interested in
TRIMMED=$(echo $BRANCH_NAME | sed -e 's:\([a-z]\+\/\)*\([A-Z]\+-[0-9]\+\).\+:\2:')
# If it isn't excluded, preprend the trimmed branch identifier to the given message
if [ -n "$BRANCH_NAME" ] &&  ! [[ $BRANCH_EXCLUDED -eq 1 ]]; then
sed -i.bak -e "1s,^,$TRIMMED: ," $1
fi

现在发生了什么事

LG-132：LG-132：LG-132：LG-132：LG-132：LG-132：LG-132：将https://git.dw.com/scm/lg/webapp的分支“开发”合并为开发

因此，每次执行修订时，都会添加分支代码。现在，我正在尝试检查提交消息中是否包含分支代码，如果是，则将其中断/返回0。

这是我到目前为止所拥有的：

#!/bin/bash
# Include any branches for which you wish to disable this script
if [ -z "$BRANCHES_TO_SKIP" ]; then
  BRANCHES_TO_SKIP=(master develop)
fi
# Get the current branch name and check if it is excluded
BRANCH_NAME=$(git symbolic-ref --short HEAD)
BRANCH_EXCLUDED=$(printf "%s\n" "${BRANCHES_TO_SKIP[@]}" | grep -c "^$BRANCH_NAME$")
# Trim it down to get the parts we're interested in
TRIMMED=$(echo $BRANCH_NAME | sed -e 's:\([a-z]\+\/\)*\([A-Z]\+-[0-9]\+\).\+:\2:')
# If it isn't excluded, preprend the trimmed branch identifier to the given message
if [ -n "$BRANCH_NAME" ] && ! [[ $BRANCH_EXCLUDED -eq 1 ]]; then
  set BRANCH_NAME|find "$TRIMMED" >nul && shouldAddCode=true || shouldAddCode=false
  if $shouldAddCode; then
    echo "test"
  else
    sed -i.bak -e "1s,^,$TRIMMED: ," "$1"
  fi
fi

我在控制台中得到了这个

找到：“ LG-132”：没有这样的文件或目录

现在此代码不起作用。我使用此代码作为参考：

set "i=hello world"
set i|find "world" >nul && set test=yes || set test=no
echo %test%
pause

我想念什么？

您的参考文献看起来不像bash代码，而是像CMD脚本。

要在bash脚本中检查某个变量是否以特定字符串开头，通常的方法是使用case ... esac构造，例如：

case "$BRANCHNAME" in
"$TRIMMED"*)
  # yes, it's there
  echo "test"
  ;;
*)
  # no, it's not there; add it
  if ! [[ $BRANCH_EXCLUDED -eq 1 ]]; then
    sed -i.bak -e "1s,^,$TRIMMED: ," "$1"
  fi
  ;;
esac

请注意奇怪的case arm语法，该语法在模式后仅带有右括号，并以双分号结尾。

最终变得有点混乱，但这就是我想出的

#!/bin/bash
# Include any branches for which you wish to disable this script
if [ -z "$BRANCHES_TO_SKIP" ]; then
  BRANCHES_TO_SKIP=(master develop)
fi
# Get the current branch name and check if it is excluded
BRANCH_NAME=$(git symbolic-ref --short HEAD)
BRANCH_EXCLUDED=$(printf "%s\n" "${BRANCHES_TO_SKIP[@]}" | grep -c "^$BRANCH_NAME$")
# Trim it down to get the parts we're interested in
TRIMMED=$(echo $BRANCH_NAME | sed -e 's:\([a-zA-Z]\+\/\)*\([a-zA-Z]\+-[0-9]\+\).\+:\2:')
TRIMMED=${TRIMMED^^}
# If it isn't excluded, preprend the trimmed branch identifier to the given message
if [ -n "$BRANCH_NAME" ] && ! [[ $BRANCH_EXCLUDED -eq 1 ]]; then
  COMMIT_MESSAGE="$(cat "$1" | sed -E "s,^#.*|$TRIMMED: *,,g")"
  echo "$COMMIT_MESSAGE" >"$1"
  sed -i.bak -e "1s,^,$TRIMMED: ," "$1"
fi

在Windows bash中查找字符串的一部分
