Recently I got a chance to taste the fish and I must say it's awesome even though I am totally into bash till now. This Fish Shell is a fully-equipped command line shell that is smart and user-friendly.
There are multiple reasons to say that it is the best tool and some of them are:
- Intelligent Auto Suggestions
- Themes support
- Scripting support -
Let's talk about it more!!!
You can find a hell number of articles about this, but I wanted to stress more on customizing your existing Fish shell.
One of my biggest questions when I initially started using Fish was how to migrate my existing bash profile to Fish Shell?.
The answer is Fairly Simple - Easy peasy!!!
~/bash_profile:
alias idea='open -a "`ls -dt /Applications/GoLand.app|head -1`"'
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home
function .runElasticSearch() {
docker run -p 9200:9200 -p 9300:9300 --name elastic -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.4.0
docker run --link elastic:elasticsearch -p 5601:5601 {docker-repo}:{version}
}
function .runZookeeper() {
cd /Users/vasubabujinagam/Documents/softwares/zookeeper/bin
./zkServer.sh start
}
function .stopZookeeper() {
cd /Users/vasubabujinagam/Documents/softwares/zookeeper/bin
./zkServer.sh stop
}
function .runKafka() {
cd /Users/vasubabujinagam/Documents/softwares/kafka_2.11
./bin/kafka-server-start.sh config/server.properties
}
This is how fish functions looks like:
Fish: ~/.config/fish/config.fish
alias idea='open -a "`ls -dt /Applications/GoLand.app|head -1`"'
set -x JAVA_HOME /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home
function .runElasticSearch
docker run -p 9200:9200 -p 9300:9300 --name elastic -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.4.0
docker run --link elastic:elasticsearch -p 5601:5601 {docker-repo}:{version}
end
function .runZookeeper
cd /Users/vasubabujinagam/Documents/softwares/zookeeper/bin
./zkServer.sh start
end
function .stopZookeeper
cd /Users/vasubabujinagam/Documents/softwares/zookeeper/bin
./zkServer.sh stop
end
function .runKafka()
cd /Users/vasubabujinagam/Documents/softwares/kafka_2.11
./bin/kafka-server-start.sh config/server.properties
end
You can see there are not much differences from Bash to Fish. Happy Fishing!!!
