ff: Just my own fork of [fd] with many incompatible changes. (unstable)
cargo install ff-find
ff lets you search for files and directories with a glob pattern.
bash
ff $HOME '*.txt'
More power (and danger) come with the --regex switch to use regex patterns.
bash
ff --regex $HOME '\.txt$'
Unicode support:
```bash ff . '?' # doesn't match filename π ff --unicode . '?' # matches filename π
ff --regex . '^.$' # doesn't match filename π ff --regex --unicode . '^.$' # matches filename π ```
This is because the pattern matches byte strings by default.
If you have a disk or partition for backup service, use the --mount flag to prevent deletion for files on it:
```bash
ff $HOME .DS_Store --mount --exec rm -v --
ff $HOME .DS_Store --mount -0 | xargs -0 rm -v -- ```
To exclude arbitrary directories or files, try the advanced features:
```bash
ff / name c++ type directory,symlink \ !path '/usr/include/' !path '/usr/bin/'
ff / name c++ and type directory,symlink \ and not path '/usr/include/' and not path '/usr/bin/'
ff $HOME iname '.chm' or iname '.pdf' or iname '*.epub'
ff $HOME iname '*.{chm,pdf,epub}' ```
```
USAGE:
ff [OPTIONS] [
OPTIONS: -g, --glob Match file paths with a glob pattern. This is the default behavior.
-r, --regex
Match file paths with a regex pattern.
-u, --unicode
Turn on Unicode support for search patterns.
Character classes are not limited to ASCII. Only valid UTF-8 byte
sequences can be matched by the search pattern.
-i, --ignore-case
Perform a case-insensitive search.
-s, --case-sensitive
Perform a case-sensitive search.
This is the default behavior.
-p, --full-path
Match the absolute path instead of only the file name or directory
name.
-L, --follow
Follow symlinks and traverse the symlinked directories.
-M, --mount
Do not descend into directories on another disk or partition, as a
symlink or normal directory may lead to a file on another file
system.
-0, --print0
Each search result is terminated with a NUL character instead of a
newline (LF) when printed.
This option does not affect --exec.
-A, --absolute-path
Relative paths for output are transformed into absolute paths.
An absolute path may not be the real path due to symlinks.
-S, --sort-path
The search results are sorted by pathname before output.
Sort by lexicographically comparing the byte strings of path
components. The search depth is also taken into comsideration.
This option also forces --exec to use a single thread for
processing.
-a, --all
All files and directories are searched.
By default, files and directories of which the names start with a
dot "." are ignored in the search.
Files ignored by patterns in .(git)ignore files are still excluded.
-I, --no-ignore
Show search results from files and directories that would otherwise
be ignored by .(git)ignore files.
-m, --multiplex
Multiplex stdin of this program so that every executed command
shares the same input.
Interactive input is disabled by caching, even if the commands run
sequentially.
-t, --type <filetype>
Filter the search by type (case-insensitive): [default: any]
directory or d: directories
file or f: regular files
symlink or l: symbolic links
executable or x: executable files
Executable files are regular files with execute permission bits set
or are symlinks pointing to the former, which means they are likely
programs that can be loaded and run on the operating system.
-d, --max-depth <number>
Limit the directory traversal to a given depth.
-c, --color <when>
Declare when to use color for the pattern match output:
auto: use colors for interactive console [default]
never: do not use colorized output
always: always use colorized output
-j, --threads <number>
The number of threads to use for searching and command execution.
0 means [default: number of available CPU cores]
--max-buffer-time <milliseconds>
The amount of time (in milliseconds) for the search results to be
buffered and sorted before streaming.
This option is mostly a stub for testing purpose.
-x, --exec <program [argument]... [;]>
Run the given command for each search result.
The search result can be represented by a pair of braces {} in the
command. If the command does not contain any {}, then a {} is
appended as an argument to the program. A single semicolon ;
terminates the argument list.
With --threads=1 commands are run sequentially. If multi-threading
is enabled and multiplexing is not enabled, commands do not receive
input from an interactive console.
If not running with a single thread, each output of the command is
buffered, reordered (printed to stdout before stderr) and
synchronized to avoid overlap.
-v, --verbose
Show warnings about file permissions, loops caused by symlinks, I/O
errors, invalid file content, etc.
-h, --help
Print help information.
Use --help to show details and full list of options.
-V, --version
Print version information.
ARGS:
<PATTERN | FILTER CHAIN>...
A regex or glob pattern for matching files. [optional]
The default patterns for regex and glob are ^ and * respectively.
The expression can also be a chain of filters with syntax as
follows:
Ordered in order of decreasing precedence:
* Grouped expression:
"(" expr ")"
* Negated expression:
"NOT" expr
"!" expr
* Both expr1 and expr2 are true:
expr1 "AND" expr2
expr1 expr2
expr2 is not evaluated if expr1 is false.
* One and only one of expr1 and expr2 is true:
expr1 "XOR" expr2
Both expressions are evaluated.
* At least one of expr1 and expr2 is true:
expr1 "OR" expr2
expr2 is not evaluated if expr1 is true.
* Only return the value of expr2:
expr1 "," expr2
Both expressions are evaluated.
Operator names are case-insensitive.
Expressions (unchained):
* Perform a case-sensitive match on file names.
name <glob pattern>
* Perform a case-insensitive match on file names.
iname <glob pattern>
* Perform a case-sensitive match on (relative) file paths.
path <glob pattern>
regex <regex pattern>
* Perform a case-insensitive match on (relative) file paths.
ipath <glob pattern>
iregex <regex pattern>
* Match specified file types.
type <file type[,file type]...>
* Always true.
true
* Always false.
false
* Always true; print the result followed by a newline.
print
* Always true; print the result followed by a NUL character.
print0
The head of a predicate is case-insensitive.
"print" and "print0" are both predicates and actions.
If no action is specified in the filter chain, all matched results
are printed on the standard output with the line terminator
determined by the option --print0.
--exec is forbidden while using a filter chain.
Please view the man page for example usage. (TODO)
NOTE: If the value of environment variable PWD is the path of a symlink pointing to the current working directory, it is used for resolving the absolute path of a relative path. ```
\<char> drops the \ and removes special
effect of a character ANYWHERE.Please note that the nitty-gritty of supported syntax may change in the future. There are still some todos noted in the source code.
