sed - “未知命令"用文件内容替换模式时 [英] sed - "unknown command" when replacing pattern with contents of file
问题描述
我尝试操纵一些模板化"文本文件.这意味着文件包含一些令牌".需要由一些实际字符串替换 - 硬编码或从其他文件中读取.
I try to manipulate some "templated" text files. Meaning that the files contain some "tokens" which need to be replaced by some actual strings - either hard coded, or readable from other files.
我有以下两行:
sed -r -e 's_<!-- cssintern -->_<style type="text/css">\n<!-- cssintern -->\n</style>\n_' -i "$out_dir_aca/books_1by1/independent/$(basename "$aca_frag").html"
sed -e '^<!-- cssintern -->^' -e '{r '"$src_dir_frags_struct/styles1.css.frag" -e 'd}' -i "$out_dir_aca/books_1by1/independent/$(basename "$aca_frag").html"
第一个工作正常.问题是第二个生成了一个未知命令".错误,我想不出如何修复它.调试输出如下(最后一行的错误文本):
The first one works fine. The problem is that the second one generates an "unkown command" error, and I ran out of ideas how to fix it. The debugging output is the following (error text on last line):
+ for aca_frag in $out_dir_aca/frags_1by1/*

sed: -e expression #1, char 1: unknown command: `^'
我用于分隔符^
、_
、/
,我在all"中播放;带有简单和双引号的方法,以及我在互联网上找到的所有其他内容.错误仍然存在这一事实没有任何改变.
I used for separators ^
, _
, /
, I played in "all" ways with simple and double quotation marks, and everything else that I found on the internet. Nothing changes the fact that the error remains.
过去我用过这条线
sed.exe -i -e '/%%H/{r ..\/##_frags_##\/out\/%%H' -e 'd}' .\out\out.frag
在 Windows cmd
脚本中,并且工作正常.(%%H
引用文件名,当用for
解析文件夹中的所有文件时).我实际上是在 Linux 中重写旧脚本,作为练习 - 希望增加简单性和额外功能.
in a Windows cmd
script, and worked fine. (%%H
references the name of the file, when parsing all the files in the folder with a for
). I am actually rewriting the old scripts in Linux, as exercize - hopefully to add simplicity and extra features.
我打算修改以下 sed
命令:
I intend to adapt the following sed
command:
sed -e '/<TEXT1>/{r File1' -e 'd}' -i File2
满足我的特殊需求.
注意:我提供了确切的文件名和路径,认为它们可能会提供一些见解.
Note: I provided the exact file names and paths, thinking that they might provide an insight.
注意:我在虚拟机中使用 Debian 10.7.
Note: I use Debian 10.7 in a virtual machine.
注意:脚本文件以#!/bin/bash -xv
开头.-xv
显然只在调试时使用,否则会丢失.
Note: the script file starts with #!/bin/bash -xv
. -xv
is obviously used only when debugging, otherwise missing.
推荐答案
The语法是(我的评论):
[2addr] {editing command # No newline between '[2addr]' and '{'!
editing command
...
}
其中 [2addr]
是例如 /filtering/
表达式.选项 -e
确实(强调我的):
Where [2addr]
is for example the /filtering/
expressions. The option -e
does (emphasis mine):
如果指定了任何 -e 或 -f 选项,则编辑命令的脚本最初应为空.每个 -e 或 -f 选项指定的命令应按指定的顺序添加到脚本中.每次添加时,如果前一次添加(如果有)来自 -e 选项,则 <newline>应插入在新添加之前.生成的脚本应具有与操作数部分中描述的脚本操作数相同的属性.
If any -e or -f options are specified, the script of editing commands shall initially be empty. The commands specified by each -e or -f option shall be added to the script in the order specified. When each addition is made, if the previous addition (if any) was from a -e option, a <newline> shall be inserted before the new addition. The resulting script shall have the same properties as the script operand, described in the OPERANDS section.
当 [2addr]
和 {
之间有换行符时,脚本无效:
When there is a newline between [2addr]
and {
the script is invalid:
$ sed -e '/something/' -e '{' -e '}' /dev/null
sed: -e expression #1, char 11: missing command
$ sed '
/something/
{
}' /dev/null
sed: -e expression #1, char 13: unknown command: `
'
将 {
与 [2addr]
一起放置可以解决问题,因为它删除了换行符:
Putting the {
with [2addr]
fixes the problem as it removes the newline:
$ sed -e '/somethimg/{' -e '}' /dev/null
所以把它和过滤表达式放在一起:
So put it with the filtering expression:
sed
-e '\^<!-- cssintern -->^{'
# ^^ ^^ here '{' is with /expression/
# or just: -e '/<!-- cssintern -->/{'
-e 'r blabla/styles1.css.frag'
-e d
-e '}' -i 'blabla/12.17 - Acatistul Sfantului Proroc Daniel.frag.html'
应该没问题.
