sed shell 變數替換 變數含有空格以及單引號問題

阿新 • • 發佈：2019-01-19

首先假設我想要echo 一個string帶有單引號怎麼實現呢？

[[email protected] ~]# echo '1'
1

[[email protected] ~]# echo "\'1\'"
\'1\'

[[email protected] ~]# echo ''\''1'\'''
'1'

但是假如我在shell中以變數的形式傳遞呢？

看下面的指令碼

[[email protected] freshexp]# more sedexptry.sh 
#!/bin/bash
file=$1          #export file
mapping=$2       #mapping config
while IFS="|" read flag old new
do
    echo "flag is "$flag
    echo $old
    echo $new
    sed s/"\($flag  ..\?\)  $old"/"\1  $new"/ $file > $file.tmp
done<$mapping
[
 
[email protected] freshexp]# more mapping.cfg 
asselv|'1'|'11111'
[[email protected] freshexp]# sh -x sedexptry.sh test.txt mapping.cfg 
+ file=test.txt
+ mapping=mapping.cfg
+ IFS='|'
+ read flag old new
+ echo 'flag is asselv'
flag is asselv
+ echo ''\''1'\'''
'1'
+ echo ''\''11111'\'''
'11111'
+ sed 's/\(asselv  ..\?\)  '\''1'\''/\1  '\''11111'\''/' test.txt
+ IFS='|'
+ read flag old new
[
 
[email protected] freshexp]#


看到沒，他的echo竟然是echo ''\''1'\'''

然後在sed中竟然是sed 's/\(asselv  ..\?\)  '\''1'\''/\1  '\''11111'\''/' test.txt

其實我想要的是        sed s/"\(asselv  ..\?\)  '1'"/"\1  '11111'"/ test.txt

其實我的目的是想將檔案

中的asselv  =  '1'   替換為 asselv  =  '1003'

在不能解決上面的單引號的問題的時候我想了另一種解決方法：

[[email protected] freshexp]# more sedexport.sh 
#!/bin/bash
file=$1          #export file
mapping=$2       #mapping config
while IFS="|" read flag old new
do
    echo $flag
    echo $new
    sed s/"\($flag  ..\?  '\)$old"/"\1$new"/ $file > $file.tmp
    mv $file.tmp $file
done<$mapping

一開始執行的不錯，但是後來發現了問題，很隱蔽，看一下執行之後的檔案就能想到錯誤錯在哪裡

[[email protected] freshexp]# ^C

mapping檔案如下 
[[email protected] freshexp]# more mapping2.cfg 
asselv|1|11111
asselv|5|55555
[[email protected] freshexp]#

看來還是的精確生成如下的sed才行 
sed s/"\(asselv  ..\?\)  '1'"/"\1  '11111'"/ test.txt

但是裡面的單引號讓我頭疼不已！！！！

----一個小測試：
