To print how many times (count) given keyword present in file using grep command in Linux
To search for exact match of given keyword in a file using grep command in Linux
To print the line no. of matches of given keyword in a file using grep command in Linux
To search a given keyword in multiple files using grep command in Linux
To suppress file names while search a given keyword in multiple files using grep command in Linux
To search multiple keywords in a file using grep command in Linux
To search multiple keywords in multiple file using grep command in Linux
To only print file names which matches given keywords using grep command in Linux
To get the keywords/pattern from a file and match with a another file using grep command in Linux
To print the matching line which start with given keyword using grep command in Linux
To print the matching line which end with given keyword using grep command in Linux
Suppose we have 100 files in a directory (dirA) and we need to search a keyword in all the files using grep command in Linux
We can use egrep command for the multiple keywords search using grep command in Linux
If you just wanna search but don't want to print on terminal or If you want to suppress error message using grep command in Linux
