It is used to match zero or more characters in a file name or a path. It seemed like I did (with some unexpected behavior with grep as I explained above). In the Bash command line interface (CLI), the wildcard character is the asterisk ( ). not -path './flash_drive_data*' I was getting nothing related to flash_drive_data. Finally, the objective of what I was doing above was to make sure that when I ran find. Why? Then, when I did grep "**" I believe I got all the files (or at least I think I did).

The 3/flas at the end is being highlighted.Ģ. ![]() local/lib/python3.7/site-packages/jedi/third_party/typeshed/third_party/2and3/flask/json/tag.pyi You can certainly wildcards in grep but they probably behave a little differently than you expect and you will probably only need them if you want to match. local/lib/python3.7/site-packages/jedi/third_party/typeshed/third_party/2and3/flask/json We’ll look at how to write those patterns in a later lesson, but in the meantime we can make good use of grep to search for lines containing a specific text string. ![]() grep is a program for searching files to find lines that match a certain pattern. If this option is used multiple times or is combined with the -e (-regexp) option, search for all. ![]() local/lib/python3.7/site-packages/jedi/third_party/typeshed/third_party/2and3/flask/sessions.pyi The easiest ways to give multiple files will be to use wildcards. f FILE, -fileFILE Obtain patterns from FILE, one per line. Is it possible to Replace wildcard strings For example, given this FIND string entered in Find and Replace. Simple search mode for literal strings, when not using regexes. local/lib/python3.7/site-packages/jedi/third_party/typeshed/third_party/2and3/flask/templating.pyi Regex syntax is a common subset of Perl, PHP and Java (see the Regex Reference). local/lib/python3.7/site-packages/jedi/third_party/typeshed/third_party/2and3/flask/signals.pyi local/lib/python3.7/site-packages/jedi/third_party/typeshed/third_party/2and3/flask/cli.pyi local/lib/python3.7/site-packages/jedi/third_party/typeshed/third_party/2and3/flask If a character vector of length 2 or more is supplied, the first element is used with a warning.
