如果[和]确实只出现在最后一列中，那么您可以使用tr删除所有[和]，据我所知，tr不算 * 通用脚本语言 *，让file.txt内容为

然后

tr -d '[]' < file.txt

给出输出

说明：我将file.txt输入到tr的stdin，并指示删除以下字符：一个月八个月一个月，一个月九个月。
然而，如果[和]可能出现在列中而不是最后一列，那么您可以按照以下方式使用GNU AWK，让file.txt内容为

[HelloWorld] 1 [Name]
Hello        2 [Name]
World        3 [Name]

然后

awk 'BEGIN{FS="[[:space:]]"}{gsub(/\[|\]/,"",$NF);print}' file.txt

给出输出

[HelloWorld] 1 Name
Hello        2 Name
World        3 Name

说明：我通知GNU AWK字段分隔符（FS）是单个空白字符，然后对于每一行，我全局地（因此gsub）使用空字符串替换文字[或（|）文字]，即在最后一个字段（$NF）中删除它

• （在gawk 4.2.1中测试）*

这个sed应该可以替换输入中任意位置的[和]：

sed -E 's/[][]//g' file

但是，如果只想从最后一个字段中删除[和]，则用途：

sed -E 's/\[([^]]*)\]$/\1/' file

为什么不使用tr：

Prompt> cat file.txt | tr -d "[" | tr -d "]" >result.txt

-d开关用于删除上述字符。
