I am wondering if there is a way to display the entire line in a data file containing specific characters in linux? For example searching for "577789999" in a file.txt should display me the line such as below
我想知道是否有办法在包含linux中特定字符的数据文件中显示整行？例如，在file.txt中搜索“577789999”应该显示如下所示的行
577789999 adef YTM 777888

that's what grep is for
这就是grep的用途
grep 577789999 file.txt
you might want to restrict the pattern to occur only in the beginning of the line:
您可能希望将模式限制为仅在行的开头发生：
grep ^577789999 file.txt

Generaly, you might use grep like that : grep "the researched string" "filename"
通常，你可以使用这样的grep：grep“研究字符串”“文件名”
It'll tells you at which line you're string is, and if you search it on "*" (All files in the current dir), it tells you in which file you're string is ;)
它会告诉你你在哪一行你是字符串，如果你在“*”（当前目录中的所有文件）上搜索它，它会告诉你你在哪个文件中是字符串;）
