BBEdit Grep/Regex 查找并替换破折号后的部分

pet*_*tsk 3 regex grep bbedit

当我想要查找并删除文章编号列中以破折号 (-) 开头的部分以及其后的所有内容时,正则表达式应该是什么样子?

我正在使用 BBEdit 搜索并替换制表符分隔的 CSV 文件中的字符串(示例如下)。

"Article number"    "Name"  "Third Column"
"Shorts Artic"  "Swa..."    "2018-07-28"
"Shorts Artic-1"    "Swa..."    ""
"Shorts Artic-2-1"  "Swa..."    "https://test-domain.com/..."
"Shorts Artic-2-2-1"    "Sw..." ""
"Shorts Artic-2-2-2-2-1"    "Ba..." "-asd"
"Shorts Artic-2-2-2-2-2-1"  "Nus..."
"Shorts Artic-2-2-2-2-2-1-1"    "Lek.."
"0858-1"    "Jacket Blue.."
"0858-2-1"  "Jacket Re.."
"0858-2-2-1"    "Int..."
"0858-2-2-2-1"  "In..."
"0858-2-2-2-2-1"    "Int..."
"0858-2-2-2-2-2-1"  "Int..."
"0858-2-2-2-2-2-2-1"    "Int..."
"0858-2-2-2-2-2-2-2-1"  "In..."
"0858-2-2-2-2-2-2-2-2"  "In..."
"0858-2-2-2-2-2-2-2-1"  "In..." "6 107-124 cm"
"stl 31-35-1-1-1-1-2-2-2-1-1"   "In..."
