如何打印字正则表达式后，但没有类似的词吗？ [英] How do i print word after regex but not a similar word?

问题描述

我想一个awk或sed的命令正则表达式后打印字。

I want an awk or sed command to print the word after regexp.

我想一个字，但不是词，类似于后找到的单词。

I want to find the WORD after a WORD but not the WORD that looks similar.

文件看起来是这样的：

 somethingsomething
 X-Windows-Icon=xournal
 somethingsomething
 Icon=xournal
 somethingsomething
 somethingsomething 

我想从一个说图标= Xournal之类Xournal之类。这是多远我来了，直到现在。我已经试过了AWK字符串太多，但它也是不成功的。

I want "xournal" from the one that say "Icon=xournal". This is how far i have come until now. I have tried an AWK string too but it was also unsuccessful.

cat "${file}" | grep 'Icon=' | sed 's/.*Icon=//' >> /tmp/text.txt

但我得到这么两种文本文件中给出了两个Xournal之类，我不想要的。

But i get both so the text file gives two xournal which i don't want.

推荐答案

使用 ^ 在该行的开头以固定的模式。你甚至可以做到直接在sed就grepping：

Use ^ to anchor the pattern at the beginning of the line. And you can even do the grepping directly within sed:

sed -n '/^Icon=/ { s/.*=//; p; }' "$file" >> /tmp/text.txt

您也可以使用awk中，我认为读好一点。使用 = 作为字段分隔符，如果场1 图标然后打印领域2：

You could also use awk, which I think reads a little better. Using = as the field separator, if field 1 is Icon then print field 2:

awk -F= '$1=="Icon" {print $2}' "$file" >> /tmp/text.txt
