I want grep to grep one word which is having spaces it
提问by Sai Srikanth
I would like to grep the word “s a i”(which has spaces in it) in a xyz.txtfile which is saved in another directory. I tried to find an answer but I didn't manage to find any. I have to use the grepcommand only.
我想在另一个目录中保存的文件中grep 单词“sai”（其中有空格）xyz.txt。我试图找到答案，但我没有找到任何答案。我只需要使用grep命令。

You can escape the space with a backslash:
您可以使用反斜杠转义空格：
grep My\ Documents

Just add quotes around your grepcommand:
只需在grep命令周围添加引号：
grep "s a i" "another directory/xyz.txt"

You can use regular expression:-
您可以使用正则表达式：-
grep -E "(s a i)" a.txt
