USAGE: ff [FLAGS] [OPTIONS] <PATTERN> [ROOT_PATH] FLAGS: -s, --case-sensitive Search case sensitively. By default, files are searched case insensitively. -D, --exclude-dir-paths Exclude paths from the search result which are directories and not files. -h, --help Prints help information -G, --ignore-gitignore Ignore searching files and directories specified in .gitignore. By default, the files and directories specified in .gitignore are included in the search results. -H, --ignore-hidden Ignore searching hidden files and directories. By default, hidden files and directories are included in the search results. -V, --version Prints version information OPTIONS: -x, --exclude <exclude> Exclude files and directories matching this regular expression from the search results. -L, --level <level> Recursively search only given level directories deep. By default no depth restriction is imposed. A value of 0 would always yield zero results. A value of 1 searches for the direct children in the given path. -j, --threads <threads> The approximate number of threads to use. A value of 0 (which is the default) results in thread count set to available CPU cores. ARGS: <PATTERN> Find files whose name (path) matches this substring or the regular expression. <ROOT_PATH> Path to the directory to search files inside.[default: `$PWD`]
