如何在搜索字符串后准确删除 1 个单词？我可以删除搜索词，但不能删除之后的词，即“utf8”

# echo "varchar(255) CHARACTER SET utf8,"
varchar(255) CHARACTER SET utf8,

# echo "varchar(255) CHARACTER SET utf8," |  sed 's/ CHARACTER SET[^ ]* / /g'
varchar(255) utf8,

预期输出：

varchar(255) ,

你是这个意思吗？

echo "varchar(255) CHARACTER SET utf8," |  sed 's/ CHARACTER SET[ a-z0-9,]*/ /g'

输出 

varchar(255)

这可能对您有用（GNU sed）：

echo "varchar(255) CHARACTER SET utf8," |  sed 's/ CHARACTER SET \w*/ /g'
