Bash 从输入文件中回显附加数据

Question

我目前有数千个 .jdx 文件，我设法找到一种方法将文件中需要的行回显到新文件中。我似乎无法做的是获取需要回显的额外数据。

这就是我希望的最终结果。

visible: true

* CAS REGISTRY NO=591-95-7
* MOLFORM=C5H8
* MW=137.3

到目前为止我想出的批处理文件是这个。

#!/bin/bash
while read -r line; do
echo \r --- > new.txt;
 echo \r visible: true >> new.txt;
        if [[ $line =~ TITLE ]] ; then echo \ title: $$line > new.txt; fi
        if [[ $line =~ DATA ]] ; then echo \ $$line >> new.txt; fi
        if [[ $line =~ CAS ]] ; then echo \ $$line >> new.txt; fi
        if [[ $line =~ MOLFORM ]] ; then echo \ $$line >> new.txt; fi
        if [[ $line =~ MW ]] ; then echo \ $$line >> new.txt; fi
 done<*.jdx
yourfilenames=`ls *.jdx`
for eachfile in $yourfilenames
do
   echo \ \($eachfile\)\[$eachfile\] >> new.txt; done

现在我似乎无法让它发挥作用。在我变得更加灰心之前，有没有人能帮助我？

谢谢

现在，我似乎无法让它发挥作用。

echo \r它并没有像你想象的那样发挥作用。

使用以下方法检查代码ShellCheck – shell脚本分析工具并修复错误/警告：

$ shellcheck myscript

Line 3:
echo \r --- > new.txt;
     ^-- SC1012: \r is just literal 'r' here. For carriage return, use "$(printf "\r")" instead.

Line 4:
 echo \r visible: true >> new.txt;
      ^-- SC1012: \r is just literal 'r' here. For carriage return, use "$(printf "\r")" instead.

Line 11:
yourfilenames=`ls *.jdx`
              ^-- SC2006: Use $(..) instead of legacy `..`.
                  ^-- SC2035: Use ./*glob* or -- *glob* so names with dashes won't become options.

Line 14:
   echo \ \($eachfile\)\[$eachfile\] >> new.txt; done
            ^-- SC2086: Double quote to prevent globbing and word splitting.

好的。终于搞定了……

抱歉，我不知道如何使用这个地方。

#!/bin/bash
echo --- > new.txt;
 echo visible: true >> new.txt &&
while read -r line; do
        if [[ $line =~ TITLE ]] ; then echo \ title: \'$line\' >> new.txt; fi
        if [[ $line =~ DATA ]] ; then echo \ --- >> new.txt; fi
        if [[ $line =~ DATA ]] ; then echo \ $line >> new.txt; fi
        if [[ $line =~ CAS ]] ; then echo \ $line >> new.txt; fi
        if [[ $line =~ MOLFORM ]] ; then echo \ $line >> new.txt; fi
        if [[ $line =~ MW ]] ; then echo \ $line >> new.txt; fi
 done<*.jdx
echo -en '\n' >> new.txt
echo -en '\n' >> new.txt

yourfilenames=`ls *.jdx`
for eachfile in $yourfilenames
do
   echo Download JDX \ \($eachfile\)\[$eachfile\] >> new.txt; done
        sed -i 's/##DATA TYPE/ * DATA TYPE/g' *.txt
