Question

我正在自动执行某些任务。

我想知道是否有可能从中间的不同文件替换每一行将需要指导者和源文件中的日期

每一行的结构都是

blahblahblah....string_I_need_to_replace....blahblahblah

我使用sed命令提取我需要替换的字符串，因为它需要从data1,data2,data3,转到data1-description; data2 - description; data3 - description

data1,data2,data3并非始终相同，只保证data1在行中

这一行

blahblah....mentor will be required.",Collaboration,Analytical Skills,Integrity & Ethics,3/1/17 20:04 ... blahblah

需要

blahblah....mentor will be required.","Collaboration-description;Analytical Skills - description; Integrity & Ethics - description " 3/1/17 20:04 ....blah blah blah

在我的解析文件的第一行包含

Collaboration-description;Analytical Skills - description; Integrity & Ethics - description

我使用sed命令在单独的文件中提取每行的内部部分Collaboration-description;Analytical Skills - description; Integrity & Ethics - description。

在我有兴趣更改的数据之前和之后有很多,和;和数字，并且计数因行而异，所以替换第n个，这将是一个问题三，当data2和data3为空时，outfile2和outfile3处理最后删除的原因

#!/bin/bash
unset LANG
cat export-14.csv | sed -n -e 's/^.*mentor will be required.",//p' > outfile
sed 's/[0-9].*//'  outfile > outfile2
sed 's/,$//'       outfile2 > outfile3
sed 's/,$//'       outfile3 > outfile4
sed 's/,/;/g'      outfile4 >outfile5
sed 's/Analytical SKills/Analytical Skills - identifying and solving problems/' outfile5 > outfile6
sed 's/Adaptability/Adaptability - embracing opportunities for improvement and resilience/' outfile6 > outfile7
sed 's/Collaboration/Collaboration - working with others/' outfile7 > outfile8
sed 's/Technology/Technology - employing current and emerging software\/tools/' outfile8 > outfile9
sed "s/Communication/Communication - articulating one\'s self/g" outfile9 > outfile10

Answer 1

您的问题I would like to know if it is possible to substitute each line from a different file in between mentor will be required and the date in the source file的答案是是，但没有简洁，可测试的样本输入和预期输出，这些信息的确可以提供尽可能多的信息。

话虽如此 - 您当前的一系列sed脚本可以重写为单个awk脚本：

awk 'sub(/^.*mentor will be required.",/,"") {
    sub(/,{1,2}[0-9].*/,"")
    gsub(/,/,";")
    sub(/Analytical SKills/,"Analytical Skills - identifying and solving problems")
    sub(/Adaptability/,"Adaptability - embracing opportunities for improvement and resilience")
    sub(/Collaboration/,"Collaboration - working with others")
    sub(/Technology/,"Technology - employing current and emerging software/tools")
    sub(/Communication/,"Communication - articulating one\047s self")
}' export-14.csv > outfile10

无论你想做什么，这都是一个更好的起点。
