itrs (it
)
itrs is a simple command line tool that provides command-line access to some
useful Rust iterator and string methods. These may be more memorable subtitute for
some quick awk
commands or common command-line idioms like sort | uniq
.
itrs provides a single executable that can access the various subcommands by name.
Installation
Installation requires cargo
cargo install itrs
Usage
After installation you should have a binary called it
avaliable. This can be
used to access the subcommands. For example, triming the leading and trailing
whitespace from a file called input.txt
and write the output to the stdout.
it trim input.txt
This could also be acomplished using awk
with something like:
awk '{$1=$1;print}' input.txt
However using the it trim
command may be more memorable, and is more performant
in most cases.
A common idiom in shell scripts is sort | uniq
for getting only the unique
lines of an input. This can be replaced by the it unique
command, which works
even on unsorted data. Under the hood this uses the Rust itertools
library's
unique method on iterators. This command can also be accessed with the alias
it uniq
(many of the subcommands have useful aliases).
More subcommands, their aliases, and their descriptions can be shown with it help
