How to use grep to find a file?
The grep command searches through the file, looking for matches to the pattern specified.
To use it type grep , then the pattern we're searching for and finally the name of the file (or files) we're searching in.
The output is the three lines in the file that contain the letters 'not'.
To list files in Linux:
The easiest way to list files by name is simply to list them using the ls command. Listing files by name (alphanumeric order) is, after all, the default.
You can choose the ls (no details) or ls -l (lots of details) to determine your view.
Which command have more searching options to search a file in file system in Linux?
Grep is a Linux / Unix command-line tool used to search for a string of characters in a specified file. The text search pattern is called a regular expression.
When it finds a match, it prints the line with the result.
The grep command is handy when searching through large log files.
grep is a command-line utility for searching plain-text data sets for lines that match a regular expression.
Its name comes from the ed command g/re/p (globally search for a regular expression and print matching lines), which has the same effect.
To grep recursively in a directory:
To recursively search for a pattern, invoke grep with the -r option (or --recursive ). When this option is used grep will search through all files in the specified directory, skipping the symlinks that are encountered recursively.
