    grep to display folders which contain files which contain a string

    As I understand it, in general terms you want to list which folders contain regular files called dev/*/* which themselves contain the string "MY_Output" (case sensitive).

    More precisely, since the "*" pattern does not match files or directories starting with a ".", you would also want to search for dev/*/*, dev/.??*/*, dev/*/.??* and dev/.??*/.??* . This is a detail that is missing from secretmike's and Brian Showalter's solutions.

    Using these four patterns ensures that you process all the files you want and that you don't get extra matches from other (deeper or shallower) files. Normally the list of matching files can be accomplished simply by running:

    The 2>/dev/null part is there to ignore errors such as when you try reading from files without permissions, like you seem to be doing (based on your answer to Imre L's answer). For best results you may want to run this command as root.

    grep search current directory

    When you want to search in all the files of the current directory, regardless of their name or extension, you can use the wildcard character after your grep command as follows:

    For example:

    Note that this command does not search in subdirectories. Instead, it tells you that model1 and model2 are directories and that they are not searched.

    grep search current directory and subdirectories

    To search within the current directory and all subdirectories, you can use the recursive -r flag as follows:

    For example:

    ‍

    As you can see,  instead of stating that model1 and model2 are subdirectories, they have been searched and two results have appeared in files within each.

    grep -r is different from grep -R

    Note that the -r flag is slightly different from  the -R flag. While -r searches all files that are present in the current directory and all subdir

    How to use "grep" command to find text including subdirectories

    (GNU or BSD)

    You can use tool to search recursively the current folder with parameter, like:

    Note: - Recursively search subdirectories.

    To search within specific files, you can use a globbing syntax such as:

    Note: By using globbing option (), it scans all the files recursively with specific extension or pattern. To enable this syntax, run: . You may also use for all files (excluding hidden and without extension) or any other pattern.

    If you've the error that your argument is too long, consider narrowing down your search, or use syntax instead such as:

    Alternatively use .

    If you're working on larger projects or big files, you should use instead, like:

    Checkout the docs, installation steps or source code on the GitHub planerat arbete page.

    It's much quicker than any other tool like GNU/BSD, , , , , or similar, since it fryst vatten built on top of Rust's regex engine which uses finite automata, SIMD and agg
