Bash sed：没有输入文件

我有一个脚本，我从一个“输入文件”中读取数据列，然后使用这些来更改另一个文件中的一些变量

这是我的脚本，标题为

如您所见，它将列表中的前几行注释误认为是命令。这里有我遗漏的东西吗？

问题是

sed -i \
  ...
  -e "s/^\([[:blank:]]*photo_directory\).*/\1 = 'photos\/photos_${fields[0]}'/i" \ 
  #-e "s/^\([[:blank:]]*RSP_alfa\).*/\1 = ${fields[6]}/i" \
  "$mesa_inlist"

在这里，列表中

$mesa\u之前的注释也注释掉了行末尾的
\
。因此，命令在该注释处结束，并且
sed-i
抱怨没有给出任何文件。之后，
bash
尝试执行
“$mesa\u inlist”
（即
inlist\u rsp\u RR\u Lyrae
）作为命令，但失败

要解决此问题，只需删除注释行


顺便说一句：使用此功能，您可以显著提高脚本的可读性

sedi() {
 mapfile -t args < <(printf -- '-e\ns/^\([[:blank:]]*%s\).*/\\1 = %s/i\n' "$@")
 sed -i "${args[@]}" "$mesa_inlist"
}

。。。由

sedi \
  photo_interval 1000 \
  profile_interval 1 \
  history_interval 1 \
  terminal_interval 4000 \
  max_num_profile_models -1 \
  RSP_max_num_periods "$max_num_periods_2"

。。。其他
sed
命令也是如此。
