fcc is a command line utility for file concatenation (with some advanced options). Besides, it also provides a library that exposes the same functionality at the command line.
By default, fcc reads input files from <STDIN> and writes the concatenation result to <STDOUT>. You can alter this behaviour by passing command line arguments. When concatenating, you can skip lines from either start or end, enforce the presence of end-of-file newline, and etc.
See fcc --help for more help information on how to use this command line utility.
Assumes we have three tabular csv files that contain identical headers. We want to join all the contents of them and preserve only one header (-H). Meanwhile, we want to make sure all files should end with a newline (-n).
bash
find [1-3].csv | fcc -nH
or
bash
echo [1-3].csv | fcc -nH
or
bash
fcc -nH -i 1.csv 2.csv 3.csv
will print the following to stdout
(header)
(contents of 1.csv)
(contents of 2.csv)
(contents of 3.csv)
For detailed documentation on how to use fcc as a library, see https://docs.rs/fcc.
Binaries for Windows, Linux and macOS are available from Github.
You can also compile the binary from source using Cargo:
bash
git clone git://github.com/mapkts/fcc
cd fcc
cargo build --release
Compilation will probably take a few minutes depending on your machine. The
binary will end up in ./target/release/fcc.
