我有一个出价电子表格，我必须替换一些值，匹配用逗号分隔的非规则模式(即 1)。 在其最小模式中，它可以是 1,1，但它可以更高，最多 10 次复制(即 1,1,1,1,1,1,1,1,1,1,1,1,1,1...)。我想将系列缩小到 1。
以下是数据框的示例：

sed尝试：
sed -i -r 's/b1,w+/1/g' file.txt
sed -i -r 's/b1.*/1/g' file.txt
我理想的输出是这样的：

我想你正在寻找类似的东西
sed -r 's/b1(,1)+b/1/g'
即匹配1后跟一个或多个,1。
看起来你想要awk '$28=1' input-file
但也许你想过滤一点并做
awk '$28 ~ "^1(,1)*$" {$28=1} 1' input-file
第一个只是用1替换第 28 列，而第 2 列仅在与正则表达式匹配时才用1替换第 28 列^1(,1)*$
