輸出的樣本，其中包括了額外的不利線：

`

我不想要包含S1B或identifier或title的行。例如。在我s1_gg.txt文件中的實際類型的輸出我想：

<str name="filename">S1A_IW_GRDH_1SDV_20161112T060623_20161112T060648_013905_01661B_ECEF.SAFE</str> 

Answer 1

有幾個缺點在你的腳本：執行後

• grep掛起，必須由CTRL + C中終結
• 您的報價非常接近。 \的行爲是爲了逃避以下字符，在特殊字符的情況下將其視爲文字，或者在正常字符的情況下將其視爲字符類。
  • 你寫了"\>而不是\">。當你寫\S\"時，你逃過了字母S和以下"字符。
  • 你應該wirtten：grep "=\"filename\">" | grep "S1A_" | grep "GRDH" fileout >> s1_gg.txt
• 你通過輸入文件到您的第3 grep電話。
  • 你應該寫：< fileout grep "=\"filename\">" | grep "S1A_" | grep "GRDH" >> s1_gg.txt
  • 這最後修正爲您提供了正確的輸出，解決了grep
