h4sh5 / rcut

rcut

A rust implementation of cut, with full string delimiters

Main differences:

• the delimeter -d supports strings, not just single characters

• -n can be used to print out the index of each field next to it, like so:

$ echo a + b + c + d | rcut -d ' + ' -n
[1]a [2]b [3]c [4]d

installation

The clean way

You need cargo and rust installed on your system first

cargo install --git https://github.com/h4sh5/rcut

The untamed way

(if you don't have cargo but have python... look, its all RCE anyway)

curl https://h4sh5.github.io/rcut/setup.py | python3

or from github raw

curl https://raw.githubusercontent.com/h4sh5/rcut/main/setup.py | python3

wget

wget -O-  https://h4sh5.github.io/rcut/setup.py | python3

The slow way

Download compiled binary from https://github.com/h4sh5/rcut/releases

usage

usage is pretty much the same as cut, and the only currently supported flags are -d and -f (as well as the new -n)

example usage:

rcut -d , -f 1 test.csv

getting the field/column number of each field (useful for finding the field number of data in files with many columns)

It will be displayed next to the field like [1]fieldone [2]fieldtwo [3]abc

rcut -d, -n test.csv

multiple fields (output default sep'd by space)

rcut -d , -f 1,2,3 test.csv

using a string as delim

rcut -d "----" -f 2 something.txt

it also reads stdin when you don't give it a file

cat /etc/passwd | rcut -d : -f 2

compile with rust

install rust, then run cargo build and find the rcut binary somewhere in target/

building with cosmopolitan libc

to build with cosmopolitan libc (to make an actual portable executable that can run on both linux, windows, mac and BSDs):

• install cosmopolitan into libcosmo

mkdir libcosmo
cd libcosmo
wget https://justine.lol/cosmopolitan/cosmopolitan.zip
unzip cosmopolitan.zip
ls -al
# should have cosmopolitan.a, ape.lds etc.
cd ../

• install rust toolchains

# on Debian / Fedora, do this
rustup toolchain install nightly-x86_64-unknown-linux-gnu
rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu
# on Alpine Linux / any with musl instead of glibc, you may need to do
rustup toolchain install nightly-x86_64-unknown-linux-musl
rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-musl

• run ./cosmo_build.sh
