Just get rid of cat and provide the list of files to grep:
只需摆脱cat并提供grep的文件列表:
grep Ya_Mahdi *.txt
While this would generally work, depending on the number of .txt files in that folder, the argument list for grep might get too large.
虽然这通常有效,但根据该文件夹中.txt文件的数量,grep的参数列表可能会变得太大。
You can use find for a bullet proof solution:
您可以使用find作为防弹解决方案:
find --maxdepth 1 -name '*.txt' -exec grep -H Ya_Mahdi {} +
