问题

英文:
I do have two shell script , read the file(file1) and remove the first field of the file ( output result redirect to the file2)
, then second script again read above modified file (file2) then add extra field to each line (file3),
How to do this in single script without using two shell script .
#!/bin/bash# loop on all .txt filesfor i in File1.txt; do# remove first columncut -d' ' -f2- < $i > File2.txtdone#!/bin/bashfilename='File2.txt'while read line; do# reading each lineecho "$RANDOM $line" >> File3.txtdone < $filenameFile1.txtDate Field2 Field320111 aaaa bbbb33111 bbbb vvvv44444 cccc ggggFile2.txtField2 Field3aaaa bbbbbbbb vvvvcccc ggggFile3.txtNew Field2 Fileld31 aaaa bbbb2 bbbb vvvv1 cccc gggg

这是一段Shell脚本代码，它从file1.txt文件中读取内容，并按行处理。以下是代码的翻译部分：
一个想法：new="新的"while read -r ignore rest_of_linedoecho "$new $rest_of_line"new=$RANDOMdone < file1.txt > file3.txt
这段代码生成的输出如下所示：
$ cat file3.txt新的 Field2 Field329258 aaaa bbbb31885 bbbb vvvv15550 cccc gggg
注意： 目前不清楚输入和输出字段的分隔符是什么，所以我假设输入使用任何空白字符作为分隔符，而输出使用单个空格作为分隔符。根据需求，可以相对容易地进行修改。
英文:
One idea:
new="New"while read -r ignore rest_of_linedoecho "$new $rest_of_line"new=$RANDOMdone < file1.txt > file3.txt
This generates:
$ cat file3.txtNew Field2 Field329258 aaaa bbbb31885 bbbb vvvv15550 cccc gggg
NOTE: it's not clear (to me) what the input/output field delimiters are so for now I'm assuming any white space on input and a single space on output; should be (relatively) easy to modify per OP's requirement
