About the concept

• Commands that were not likely.
• A command written in a Bash script.
• Specializing in command line operation.
• Complex processing can be expressed with just a few characters.

Installation

Dependencies

• bash>=5.0
• awk
• sed(GNU)
• grep(GNU)
• coreutils(GNU)
• findutils(GNU)

Tips: Install the above and install it with the command corresponding to each of the following after passing through PATH.

MacOS users

# Install
$ brew tap redpeacock78/tools
$ brew install exutils

# Update
$ brew update && brew reinstall exutils
(In the future, we plan to migrate from "brew reinstall" to "brew upgrade" command.)

# Uninstall
$ brew uninstall exutils

Linux users

# Install
$ git clone https://github.com/redpeacock78/exutils.git
$ cd exutils
$ ./install.sh

# For zsh, yash, fish, etc., change the .bashrc part accordingly.
$ echo export PATH='$HOME/.exutils/bin:$PATH' >> ~/.bashrc
$ source ~/.bashrc

# Update
$ cd exutils
$ git pull
$ ./install.sh --update

# Uninstall
$ cd exutils
$ ./install.sh --uninstall

### It is possible to install as above, but if you use Linuxbrew you can install it in the same way as MacOS. ###

Docker users

When installing using Docker, there is no need to install Dependencies.

# Install
$ docker pull redpeacock78/exutils

# Write the following function in .bashrc etc.
exutils(){
  [ -t 0 ] && T="t" || T=""
  docker run -i$T --rm docker.io/redpeacock78/exutils "$@"
}
export -f exutils

# Run!
$ source ~/.bashrc
$ exutils prim -v
prim 0.0.1

# Update
$ docker pull redpeacock78/exutils && docker rmi -f $(docker images | grep docker.io/redpeacock78/exutils | grep none | awk '{print $3}')

# Uninstall
$ docker rmi -f $(docker images | grep docker.io/redpeacock78/exutils | grep latest | awk '{print $3}')

I want to use it easily without installing :-)

When using without installation, the following items are required in addition to Dependencies at installation.

Dependencies

• Internet connection
• curl

# If you want to use it permanently.
# Write the following in .bashrc etc.
exutils(){
  if [[ "${1}" == help ]] || \
     [[ "${@}" == version ]]; then
    bash <(curl -s "https://raw.githubusercontent.com/redpeacock78/exutils/master/docker/bin/${1}") "${2}"
  else
    bash <(curl -s "https://raw.githubusercontent.com/redpeacock78/exutils/master/bin/${1}") "${@:2}"
