Question

我正在尝试完成以下任务：

sed "s/{{HELP}}/$(dist/forge-cli.phar --no-ansi)/g" < post-build-hooks/readme.md.template > readme.md

此处的目标是从dist/forge-cli.phar获取结果，该结果显示该命令的帮助页面，并将其写入我的readme.md文件。但是，我收到以下错误：

sed: 1: "s/{{HELP}}/Console Tool ...": unescaped newline inside substitute pattern

dist/forge-cli.phar的输出包含多行。输出在这里：

Console Tool

Usage:
  [options] command [arguments]

Options:
  --help           -h Display this help message.

所以这是最后一个问题。我怎样才能消毒＆＃34;我的phar命令的输出是否正确地为sed命令转义它？

Answer 1

使用以下命令工作！

sed "s/{{HELP}}/$(dist/forge-cli.phar --no-ansi | gsed "s/$/\\\/g") /g" post-build-hooks/readme.md.template > readme.md

Answer 2

假设{{HELP}}在文件中位于其自己的行上，您可以使用awk执行此操作：

awk -v h="$(dist/forge-cli.phar --no-ansi)" '/{{HELP}}/{print h;next}1' in > out

当输入文件中匹配/{{HELP}}/时，请打印变量h的内容，然后跳到下一行。否则，最后的1只表示awk打印该行。

这只需要调用awk一次并打印h的内容，无论它是否包含shell可能解释的任何其他字符。

sed Sanitize Muti-Line Substitution
