我们有一种ASCII艺术,如下所示
ART _____
ART | __ \
ART | |__) |__ ___ _ __
ART | ___/ _ \/ _ \ '__|
ART | | | __/ __/ |
ART |_| \___|\___|_|
ART
ART
我们有一个变量${art}=“123456”,并希望用${art}替换art,因此系统将按如下方式打印标准输出
123456 _____
123456 | __ \
123456 | |__) |__ ___ _ __
123456 | ___/ _ \/ _ \ '__|
123456 | | | __/ __/ |
123456 |_| \___|\___|_|
123456
123456
我已经按照这篇文章的建议试过了
sed -i "s/ART/${art}/g" ascii-art
显示以下错误消息:
sed: -e expression #1, char 6: unterminated `s' command

有什么想法吗?

最佳答案
如果$art
包含/
,则可能需要反斜杠或使用其他分隔符。
或者,使用Perl:
perl -i -pe 's/ART/$ENV{art}/g' -- file
当导出
$art
时,这将起作用,如果不是,只需为命令导出它:art=$art perl ...
