How to find files that contain multiple keywords?
I’m looking for a way to list all files in a directory that contain the full set of keywords I’m seeking, anywhere in the file. So, the keywords need not to appear on the same line. One way to do this would be: Three keywords is just an example, it could just as well be two, or four, and so on.
How to find the file name and path?
Name is the file name with the extension, ie. File1.txt. BaseName is the file name without the extension, ie. File1. FullName is the path, ie. C:folderFile1.txt. You don’t have to loop thru the files you are searching for, you can check if the file is in the list with -contains.
How to find all files with name containing string?
find. -maxdepth 1 -name “*string*” -print It will find all files in the current directory (delete maxdepth 1 if you want it recursive) containing “string” and will print it on the screen. If you want to avoid file containing ‘:’, you can type: find. -maxdepth 1 -name “*string*” ! -name “*:*” -print
Which is the general form of a file name?
A path, the general form of a filename or of a directory name, specifies a unique location in a file system. It doesn’t even require an extension, as other mechanisms work out the filetype. Systems can use either absolute or relative paths.

How to find lines which are not present in another file?
By default, comm outputs 3 columns: left-only, right-only, both. The -1, -2 and -3 switches suppress these columns. So, -23 hides the right-only and both columns, showing the lines that appear only in the first (left) file.
How to find all keywords in a Python file?
I also experimented with a Python script using two strategies: searching for all keywords line by line, and searching in whole file keyword by keyword. The second strategy was faster in my case. But it was slower than just using grep, finishing in 33 seconds. Line by line keyword matching finished in 60 seconds.
How long does line by line keyword matching take?
Line by line keyword matching finished in 60 seconds. The script given by terdon finished in 54 seconds. Actually it took 39 seconds of wall time, because my processor is dual core. Which is interesting, because my Python script took 49 seconds of wall time (and grep was 29 seconds).
