Find and Replace

Search & Replace some patterns within your files with the speed and robustness of Rust.

Installation (Linux)

You need to have Rust and Cargo installed on your machine to run this tool. Official installation steps here.

git clone https://github.com/Rayanworkout/Find-and-Replace.git
cd Find-and-Replace
cargo build --release

sudo mv target/release/fnr /usr/local/bin

You can now call the binary from anywhere in your terminal.

Some examples

Find a pattern 'hello' in files of the current folder without replacing it.

fnr hello new

Find a pattern 'hello' in files of the current folder (recursively) and replace it with 'new'.

fnr hello new --write

For any lookup or replacement, you can activate verbose mode.

Note the use of "_" to indicate that we only want to perform a lookup.

fnr hello _ --verbose # or -v

You can also perform a case-insensitive search / replacement.

fnr hello new --ignore-case  # or -i

Note that ignored path(s) should be absolute path(s), otherwise it won't be taken into account.

Find a pattern 'hello' in files of the current folder, excluding the 'Desktop' folder and replace it with 'new'.

fnr hello new --omit ~/Desktop  # or -o ~/Desktop

You can also omit multiple folders.

fnr hello new --omit ~/Desktop/ ~/Another/

Including hidden files in your search.

fnr hello new --hidden --omit ~/Desktop/ ~/Desktop/foo

Only search for files with a specific extension (use glob patterns) inside the home directory.

fnr hello _ ~ --type *rs  # or -t *rs

You can also check for a specific pattern using one or 2 wildcards. Here we search only in files with the name ending with "some.txt".

fnr old_pattern new_pattern ~/Desktop/ -t "*some.txt"

Wildcards can be used in many ways. Here we search within files starting with "d" and ending with "e.txt".

fnr old_pattern new_pattern ~/Desktop/ -t "d*e.txt"

Ignore files with a specific extension.

fnr hello new --type-not *rs  # or -T *rs

You can also search / ignore multiple file types or patterns. Here, we allow only files with .rs and .toml extension.

fnr old new --type *rs *toml

As an example, the equivalent to the following find command

find ~/Desktop/ -type f -name "*txt" -exec cat {} \; | grep hello

would be

fnr hello _ ~/Desktop/ -t *txt

At any moment, feel free to hit

fnr --help

to get a list of all available options.

Usage

fnr [OPTIONS] <PATTERN> <NEW_PATTERN> [PATH]

# or if you prefer

fnr <PATTERN> <NEW_PATTERN> [PATH] [OPTIONS]

⚠️ Binaries and non UTF-8 files are skipped.

If no path is provided, the tool will search in the current folder.

All options have a short version, excluding --write and --hidden flags.

All options:

      --write
          Write changes to disk.

  -v, --verbose
          Print additional information about files searched or errors.
  -i, --ignore-case
          Perform a case-insensitive search. Default is case-sensitive.
  -t, --type [<SELECTED_FILE_TYPES>...]
          Only search files matching <file_type> or glob pattern.
  -T, --type-not [<IGNORED_FILE_TYPES>...]
          Ignore files matching <file_type> or glob pattern.
