Linux Find string __linux

If you want to find "hello,world!" in the current directory String, you can do this:

Grep-rn "hello,world!" *: Indicates all files in the current directory, or it can be a filename

-R is recursive lookup

-N is the line number displayed

-R Find all files contain subdirectories

-I ignores case

Here are some interesting command line arguments:

Grep-i pattern Files: case-insensitive search. The default case is case-sensitive,

Grep-l pattern Files: Only the matching file names are listed,

Grep-l pattern Files: Lists mismatched file names,

Grep-w pattern files: matches only the entire word, not part of the string (such as matching ' magic ', not ' magical '),

Grep-c number pattern files: matching contexts show [number] rows,

grep pattern1 | PATTERN2 files: Displays rows that match pattern1 or pattern2.

grep pattern1 Files | grep pattern2: Displays rows that match both PATTERN1 and pattern2.

Here are some special symbols for searching:

\< and > mark the beginning and end of the word separately.

For example:

grep man * will match ' Batman ', ' manic ', ' man ' and so on,

grep ' \
